Fact Checked

Key statistics

Nearly 65% of U.S. shelters are now considered no-kill, up from just 24% in 2016.

The national shelter save rate is 83-85%, meaning 4 out of 5 pets now make it out of shelters alive.

689,000 dogs and cats were still euthanized in U.S. shelters in 2023 — down from 2.6 million in 2011 and 15 - 20 million in the 1970s.

Texas, California, North Carolina, Florida, and Louisiana have the highest euthanasia rates

Delaware and New Hampshire are the only official no-kill states, maintaining a 90%+ save rate statewide.

Austin, TX has maintained a 95%+ live release rate for over a decade.

Shelters experiencing overcrowding have euthanasia rates up to 3x higher than those with steady adoption and intake balances.

Pit Bulls make up 30–40% of shelter dog intakes and have lower adoption rates. In some areas, up to 93% of Pit Bulls are euthanized due to breed bans, low adoption demand, and stigma.

Shelters with strong community funding and volunteer programs are 40% more likely to reach no-kill status than underfunded shelters.

Fostering just 2% more pets nationwide could completely eliminate euthanasia for space-related reasons, preventing thousands of unnecessary deaths.

Only 20% of U.S. states require shelters to publicly report euthanasia statistics.

85% of people support no-kill shelters, yet only 40% adopted their last pet from a shelter.

Germany, Sweden, and the UK have achieved de facto no-kill through strict pet ownership laws and strong sterilization programs.

Taiwan made shelter euthanasia illegal in 2017, while the U.S. still has no federal no-kill law.

Imagine walking into a shelter where every pet has a second chance. Every corner holds a hopeful little face, every cat's purr is a promise of a future home, and every wagging tail is a celebration. Just a few decades ago, this was far from reality - millions of animals never made it out alive.
Today, the no-kill movement is rewriting history. Across the U.S., shelters have drastically reduced euthanasia, saving millions of dogs and cats through adoption programs, spay and neuter efforts, and community initiatives. But the fight isn't over yet.
What's working? Where are we falling short? And how can we finally reach a future where no pet loses its life in a shelter?
Despite progress, nearly 1 million shelter pets are still euthanized every year. Some states have reached no-kill status, while others struggle with overcrowding, underfunding, and outdated policies. We're in 2025, and the question remains: Has America achieved no-kill status? Will this be the year that no healthy, adoptable pet is euthanized?
In this article we really wanted to take a close look at the numbers, exploring how euthanasia rates have dropped, which shelters are making the biggest impact, and what's still needed to make no-kill a reality across the country.

The Evolution of No-Kill Shelters in the U.S.

The journey toward a no-kill nation didn't happen overnight. For many years shelters across the U.S. euthanized millions of animals because they were overcrowded, underfunded, and following outdated policies. But thanks to advocacy, smarter shelter strategies, and a shift in public attitudes, things have changed in a big way.

Here's how the no-kill movement has evolved:

📌 1970s–1990s: The Crisis and First Signs of Change
✔ 15–20 million shelter animals euthanized annually in the 1970s, with minimal efforts to rehome or provide alternatives.
✔ The first high-volume spay/neuter programs launch, helping reduce unwanted litters.
✔ 1984: Best Friends Animal Society is founded, later becoming a national leader in no-kill advocacy.
✔ 1994: San Francisco becomes the first U.S. city to commit to no-kill policies, proving large-scale lifesaving was possible.
📌 2000s–2010s: The No-Kill Movement Gains Momentum
✔ Nationwide adoption campaigns and “Adopt, Don't Shop” messaging become mainstream.
✔ 2004: The Asilomar Accords introduce standardized data tracking, helping shelters measure progress.
✔ 2010: The Humane Society of the U.S. (HSUS) declares that high euthanasia rates are “no longer acceptable.”
✔ 2019: Delaware becomes the first official no-kill state, proving statewide success is achievable.
📌 2020s: The Race to 2025
✔ Nearly 65% of shelters in the U.S. are now no-kill (up from 24% in 2016).
✔ The U.S. shelter save rate has risen to 83–85%, a historic high.
✔ Best Friends Animal Society leads the national push for No-Kill 2025, aiming to ensure a 90%+ save rate nationwide.
✔ More cities and states, like Austin, TX, and New Hampshire, sustain long-term no-kill success.
Decline in U.S. Shelter Euthanasia Rates

Where the U.S. Stands Today: Shelter Stats and Trends

The no-kill movement has made incredible progress, but where do things stand right now? While the numbers are encouraging, there's still work to be done to ensure every adoptable pet has a chance at a safe and loving home.

The No-Kill Benchmark: Are We There Yet?

For a shelter to be considered no-kill, it must achieve a 90% save rate, meaning at least 9 out of 10 animals leave alive through adoption, rescue transfers, or reunification with their owners.
As of 2023:
Nearly 65% of U.S. shelters are now no-kill, a massive increase from just 24% in 2016.
The national save rate has climbed to 83–85%, meaning about 4 out of 5 shelter pets are making it out alive.
✔ Some states, like Delaware and New Hampshire, have fully reached no-kill status, while others - particularly in the South - are still working to close the lifesaving gap.

How Many Pets Are Still Being Euthanized?

Shelter euthanasia has dropped over 90% since the 1970s, but nearly 689,000 dogs and cats were still euthanized in shelters in 2023. While this number is the lowest in history, it's still too high.
📌 The goal? Reduce preventable euthanasia to near-zero by making lifesaving programs accessible to every shelter in the country.

What's Driving the Progress?

The decline in shelter euthanasia is the result of many efforts that have reshaped the way shelters operate:
Widespread Spay/Neuter Programs – Fewer unwanted litters mean fewer pets entering shelters in the first place.
Increased Shelter Transparency and Data Tracking – Organizations like Best Friends Animal Society and Shelter Animals Count have made it easier to identify problem areas and improve outcomes.
Growing Public Support for Adoption – The "Adopt, Don't Shop" movement has shifted public attitudes, making shelter adoption more mainstream.
Rescue Transfers and Transport Programs – Moving pets from overcrowded, high-risk shelters to areas with more adopters has saved thousands of lives.
Foster Programs and Community Engagement – More shelters are relying on foster homes to keep animals out of cages and in loving temporary homes until they find permanent families.

How the U.S. Compares to Other Countries in No-Kill Efforts

While the U.S. has made significant strides toward becoming a no-kill nation, other countries have already achieved it. Looking at global shelter policies, we can see what's working elsewhere and what lessons we can apply to save even more animals.
Shelter Euthanasia Rates Around the World

🔍 What No-Kill Countries Did Right

They Enforced No-Kill Laws
Countries like Germany and Taiwan enforce legal no-kill policies, ensuring that euthanasia is only used for medical or severe behavioral cases. In contrast, the U.S. relies primarily on voluntary efforts and nonprofit initiatives.
They Made Spay/Neuter a National Priority
Nations with low euthanasia rates have strong mandatory spay/neuter laws or well-funded sterilization programs. In contrast, the U.S. still struggles with stray populations, particularly in Southern states with lower spay/neuter rates.
They Changed Public Perception of Shelter Pets
In many European countries, adopting from shelters is the norm, and buying pets from breeders or pet stores is less common. Meanwhile, in the U.S., public education campaigns have improved adoption rates, but some communities still hesitate to adopt shelter animals due to outdated stigmas.
They Found Humane Solutions for Feral Cats
India and other no-kill nations embraced TNR (Trap-Neuter-Return) programs instead of euthanizing community cats. India's focus on sterilization has stabilized populations without mass culling. Expanding TNR in the U.S. could drastically reduce feline euthanasia rates.
📌
Why This Comparison Matters: These examples show that a no-kill nation is possible. With stronger policies, better public education, and increased funding for lifesaving programs, the U.S. could join the ranks of countries where shelter euthanasia is a thing of the past. If other countries have achieved no-kill, the U.S. can too.

What's Stopping More Shelters from Going No-Kill?

Many shelters face major hurdles that prevent them from reaching a 90% save rate. Truth is, not all shelters have the same resources, support, or policies in place to ensure that every adoptable pet gets a second chance.
Some shelters are overcrowded and underfunded, struggling to care for the sheer number of animals that arrive each day. Others face low adoption rates, making it difficult to move pets into homes quickly enough to keep up with incoming strays and surrenders. In some areas, breed-specific legislation, limited spay/neuter access, and outdated euthanasia policies create additional roadblocks.
Becoming no-kill depends on community involvement, legislative action, and access to resources.
Here's a closer look at the biggest challenges still standing in the way of a fully no-kill nation:

1.Overcrowding and Limited Space

Many shelters - especially open-admission municipal shelters - are forced to take in every stray, surrendered, or abandoned pet, regardless of their capacity. When kennels are full, difficult decisions have to be made.
🐾 What this means for shelters:
✔ High-intake shelters in crowded urban areas or regions with loose spay/neuter laws often struggle to keep up.
✔ Without serious foster programs or adoption initiatives, pets may be euthanized simply due to space constraints.
✔ Rural areas often have fewer adopters and fewer transport networks, making it harder to move pets to areas with higher demand.
📊
A 2023 report found that shelters with overcrowding issues have euthanasia rates up to 3x higher than those with steady adoption and intake balances.

2. Funding and Staffing Shortages

The reality is that many shelters operate on very tight budgets, especially government-run shelters that rely on taxpayer dollars. Without funding, shelters can't afford to expand, improve facilities, or hire enough trained staff.
🐾 What this means for shelters:
✔ Low-budget shelters often lack veterinary care, making it difficult to treat minor medical issues and keep animals adoptable.
✔ Understaffed shelters can't provide enrichment, training, or behavioral rehabilitation, leading to more pets being labeled as “unadoptable.”
✔ Shelters with limited marketing budgets struggle to attract adopters, leaving pets sitting in kennels for months.
📊
Shelters with strong community funding and volunteer programs are 40% more likely to reach no-kill status than underfunded shelters.

3. Low Adoption and Foster Rates in Some Regions

Adoption rates vary significantly across the U.S. In some states, pet adoption is so successful, while in others, shelters struggle to find enough homes.
🐾 What this means for shelters:
✔ Areas with lower pet adoption rates experience longer shelter stays, increasing the risk of euthanasia.
✔ In some rural areas, fewer people spay/neuter their pets, leading to constant intake of unwanted litters.
✔ Some shelters don’t have strong community outreach programs, meaning fewer people even know about the adoptable pets waiting for homes.
📊
In 2023, the five states with the highest shelter euthanasia rates (Texas, California, North Carolina, Florida, and Louisiana) accounted for over 50% of shelter pet deaths nationwide.

4. Breed-Specific Challenges and Misconceptions

Certain breeds, especially large dogs and bully breeds, face higher euthanasia rates due to stigma, restrictive laws, and lower adoption demand.
🐾 What this means for shelters:
✔ Many cities still ban breeds like Pit Bulls, making it nearly impossible to adopt them out.
✔ Large dogs generally have longer shelter stays compared to smaller breeds.
✔ Public misconceptions about certain breeds make adopters hesitant, even when dogs have no behavioral issues.
📊
Pit Bulls make up nearly 30–40% of shelter dog intakes, yet in some regions, 93% of them are euthanized due to low adoption rates.

5. Lack of Spay/Neuter Access in Certain Areas

While many states have successful spay and neuter programs, others still struggle with high rates of pet overpopulation.
🐾 What this means for shelters:
✔ Unaltered pets reproduce rapidly, increasing shelter intake year after year.
✔ Some areas lack low-cost spay/neuter clinics, making it difficult for owners to fix their pets.
✔ Without TNR (Trap-Neuter-Return) programs for feral cats, shelters end up euthanizing thousands of kittens every year.
📊
In states with mandatory spay/neuter programs for shelter pets, intake rates are 25% lower than states without these policies.

6. Gaps in Shelter Policies and Legislation

Unlike some countries where shelter euthanasia is strictly regulated, the U.S. has no federal law requiring shelters to prioritize life-saving efforts. Policies differ wildly between states.
🐾 What this means for shelters:
✔ Some states require shelters to hold animals for a certain period before euthanasia, while others allow euthanasia within hours of intake.
✔ Transparency laws vary. Some shelters report euthanasia numbers publicly, while others do not.
✔ Some states have no laws requiring shelters to work with rescues, meaning adoptable pets are sometimes euthanized despite available alternatives.
📊
Only 20% of U.S. states require shelters to publicly report euthanasia statistics, making it difficult to track nationwide progress.

7. Public Misconceptions and Awareness Gaps

Even though no-kill shelters are growing, many people still don't fully understand what no-kill means or how they can help.
🐾 What this means for shelters:
✔ Some people assume “no-kill” means shelters never euthanize animals, when in reality, a no-kill shelter can still euthanize up to 10% of pets for severe medical or behavioral issues.
✔ Potential adopters may not realize how many shelter pets need homes, leading them to buy from breeders instead.
✔ Many people believe only mixed-breed pets end up in shelters, but purebred dogs and cats make up nearly 25% of shelter populations.
📊
Surveys show that 85% of people say they support no-kill shelters, yet only 40% of pet owners adopted their last pet from a shelter.
No-kill shelters have made amazing progress, but the final push toward a no-kill nation requires tackling these remaining challenges:
✔ More funding & resources
✔ Widespread spay/neuter & TNR programs
✔ Public education & adoption awareness
✔ Legislative action to standardize shelter policies
By addressing these barriers, we can save even more lives and ensure that every adoptable pet gets a second chance.

The No-Kill Success Stories: Cities and Shelters Leading the Way

While some shelters are still working toward no-kill status, others have already proven that it’s possible. Across the country, cities and organizations have transformed their shelter systems, proving that with the right approach, high save rates can be achieved.

🏆 Austin, TX – The Largest No-Kill City in the U.S.

Austin became the largest no-kill city in America in 2011 and has maintained a live release rate (LRR) of over 95% for more than a decade. This success is largely due to its citywide ordinance requiring the municipal shelter to maintain a 90%+ save rate and its partnership with Austin Pets Alive!, an innovative nonprofit that specializes in saving at-risk animals.
What made it work?
✔ A city ordinance mandating no-kill policies
✔ Heavy investment in foster care and adoption programs
✔ Specialized rescue efforts for medical and behavioral cases
✔ Strong collaboration between public and private organizations
🔹 What other shelters can learn: Legislative support + public-private collaboration = a sustainable no-kill model.

🏆 Kansas City, MO – From High-Kill to No-Kill in Record Time

In 2012, Kansas City's shelter had a 63% save rate and was overcrowded, underfunded, and struggling. But after KC Pet Project nonprofit took over operations, the city turned things around fast. By 2018, Kansas City reached a 96% save rate and became a leading example of a well-run, high-volume no-kill shelter.
What made it work?
✔ Transitioning shelter operations from the city to a nonprofit
✔ Expanding community involvement with volunteer and foster programs
✔ Increasing adoption events and marketing campaigns
✔ Offering behavior rehabilitation programs for hard-to-adopt dogs
🔹 What other shelters can learn: Nonprofit management + community engagement = lifesaving impact.

🏆 Portland, OR – A No-Kill Network That Works

Portland took a regional approach to no-kill, forming the Animal Shelter Alliance of Portland (ASAP), a coalition of municipal shelters, private rescues, and veterinary clinics. Together, they achieved a 94% save rate and ensured that no healthy, adoptable pet is euthanized in the region.
What made it work?
✔ A regional coalition of shelters and rescues working together
✔ A shared database system to track and manage shelter animals across multiple facilities
✔ Community-wide spay/neuter efforts to reduce intake
✔ Relocation and transport programs to move animals to areas with higher adoption demand
🔹 What other shelters can learn: Collaboration across multiple shelters = greater lifesaving capacity.

🏆 Jacksonville, FL – No-Kill Through a Citywide Effort

Jacksonville has been a no-kill city since 2014, thanks to a coordinated effort between Jacksonville Humane Society, Jacksonville Animal Care & Protective Services, and First Coast No More Homeless Pets. Their approach focused on high-volume spay/neuter services, strong adoption marketing, and safety-net programs to keep pets out of shelters.
What made it work?
✔ Large-scale low-cost spay/neuter programs to prevent unnecessary intake
✔ A strong safety net for pet owners, including food assistance and vet care subsidies
✔ Free and low-cost adoption events to encourage placement of shelter animals
✔ Strong public engagement campaigns and citywide advocacy
🔹 What other shelters can learn: Investing in spay/neuter + community support = fewer animals entering shelters.

🏆 Tompkins County, NY – The First No-Kill County in the U.S.

Back in 2001, Tompkins County, New York, became the first county in the U.S. to achieve no-kill status. The SPCA of Tompkins County transformed its shelter system under the leadership of no-kill advocate Nathan Winograd, proving that even an open-admission shelter can reach a 90%+ save rate.
What made it work?
✔ Leadership that committed fully to no-kill policies
✔ A strong community-driven foster and adoption network
✔ Proactive pet retention programs to reduce owner surrenders
✔ Strong fundraising efforts to improve shelter resources
🔹 What other shelters can learn: Leadership + commitment to no-kill principles = a shelter system that saves lives.

🔥 Common Themes of No-Kill Success Stories:

Public-private partnerships between government shelters and nonprofit rescues

Proactive spay/neuter programs to reduce intake

Community-supported foster programs to free up shelter space

Innovative adoption campaigns to move animals out faster

Leadership that commits to lifesaving, even when it's difficult

These cities and shelters are making an impact and proving that a no-kill nation is within reach.

The Future of No-Kill: What's Needed to Get to 100%?

While nearly 65% of shelters in the U.S. have reached no-kill status, hundreds of thousands of adoptable pets are losing their lives each year simply because shelters lack space, resources, or community support.
Reaching a fully no-kill nation requires lifesaving programs, advocating for smarter policies, and ensuring that every pet has the opportunity to find a loving home - no matter where they are.

Here is what we at PetRadar think it will take to close the gap and create a future where every healthy and treatable pet has a chance at a home:

1. Expanding High-Impact Lifesaving Programs

Many shelters struggling to reach no-kill don't lack the will, but lack the means. Expanding proven programs that prevent unnecessary euthanasia is of huge importance.
More Spay/Neuter Initiatives – Reducing the number of unwanted litters remains one of the most effective ways to decrease shelter intake. Expanding free and low-cost spay/neuter clinics, particularly in underserved areas, will prevent overcrowding before it starts.
Community Cat TNR (Trap-Neuter-Return) Programs – The majority of shelter euthanasia still involves cats, especially unweaned kittens. Instead of bringing in feral or free-roaming cats that aren't adoptable, shelters need more support for TNR programs, which allow these cats to live safely in the community while preventing future litters.
Foster Programs to Reduce Overcrowding – If more people opened their homes, even temporarily, fewer animals would be at risk. Fostering takes pressure off shelters, gives pets a stress-free environment, and increases their chances of adoption. Encouraging even short-term “weekend fostering” programs can help keep shelters from reaching capacity.
Improved Pet Retention Efforts – Many pets are surrendered due to solvable problems such as medical costs, housing restrictions, or minor behavioral issues. Offering pet food banks, financial aid for veterinary care, and free training resources could prevent countless pets from entering the shelter system in the first place.

2. Expanding High-Impact Lifesaving Programs

No-kill shelters are thriving in some parts of the country, while others are still struggling. Why? In many cases, it's a policy problem.
Mandatory Shelter Transparency – Only a few states require shelters to report their euthanasia numbers. Nationwide tracking and public reporting would identify the areas that need the most help and hold shelters accountable for improving outcomes.
More States Passing No-Kill Laws – Some states, like Delaware, have implemented laws requiring shelters to exhaust all rescue and adoption options before euthanizing an animal. Expanding these laws nationwide could create a safety net for shelter pets.
Stronger Tenant Protections for Pet Owners – One of the top reasons pets are surrendered to shelters is housing restrictions - landlords not allowing pets or charging excessive fees. Encouraging pet-friendly housing policies (or banning breed-based restrictions) could prevent thousands of unnecessary surrenders.
Incentives for No-Kill Compliance – Shelters that reach a 90%+ save rate should receive state or federal grants to continue improving their programs. Providing funding for no-kill initiatives will make lifesaving efforts sustainable

3. Public Awareness & Cultural Shifts

A no-kill nation isn't just about what shelters do, but it's also about what WE do. The more people understand and support no-kill efforts, the faster we'll get there.
Changing How People Get Pets – Shelters and rescues need to be the first stop for potential pet owners. Promoting “Adopt, Don't Shop” and making the shelter adoption process easier and more accessible will help more pets find homes.
Breaking the Myths About Shelter Pets – Many people still believe shelter pets are “broken” or that specific breeds are bad family dogs. Public education campaigns (especially in areas with high euthanasia rates) are needed to shift perspectives and increase adoption rates.
Community Engagement & Volunteering – Many no-kill shelters rely on volunteers and foster networks. The more people willing to help, the more animals that can be saved. Encouraging people to foster, donate, or volunteer at their local shelter can make a direct impact.
Stronger Social Media & Networking for Pets in Need – The power of social media in rehoming pets has never been stronger. Promoting shelter animals online, making adoption stories go viral, and using digital tools to connect pets with potential adopters could save countless lives.

A Nationwide No-Kill Commitment

The U.S. is closer than ever, but getting to 100% no-kill nationwide requires a lasting commitment.

If every shelter in the U.S. implemented proven no-kill programs, expanded foster and adoption efforts, and had the funding to sustain these changes, the U.S. could reach full no-kill status within a few years 🐾

If just 2% more pet-owning households fostered or adopted from shelters, euthanasia for space could be eliminated entirely 🐾

If state and local governments prioritized no-kill policies and funding, even struggling shelters could transform into lifesaving organizations 🐾

The No-Kill Future is in Our Hands!
No adoptable pet should lose its life due to lack of space or resources. Every shelter, every community, and every pet parent has a role to play in making no-kill a nationwide reality.
The U.S. has already come so far, and now, it's about closing the gap and ensuring every single pet gets the second chance they deserve, because in the end, the goals is not about the numbers but about the lives we save.❤️🐾
