What is lost dog syndrome?

Lost dog syndrome or missing dog syndrome refers to a dog's behavior when they go missing. It usually shows itself as:

Increased fear and nervousness around people

Disinterest in people and even owners

Sole focus on finding food and shelter

Hiding

Lost dogs can switch very quickly into this 'survival mode', which is an instinct that helps them cope with severe stress and fear. This sometimes means that when you find your lost pet, they may not even recognize you or come to you. But don't panic—this is temporary!

Why does lost dog syndrome happen?

The reason this happens is because of a sudden increase in stress, leading to a quick depletion in a hormone called serotonin. This directly impacts your dog's behavior, triggering their fight-or-flight instinct and even affecting their short-term memory.
The fight-or-flight instinct is something all animals, including humans, experience. It's the way our bodies cope and survive extreme emotions and experiences. So, when a dog finds itself in unknown territory, with no idea how to find their way back home, they'll start to panic.

How to help your dog when they return home

When your dog returns home, sometimes they won't be able to snap out of this survival mode instantly. This can be understandably disheartening for owners, especially if their pup doesn't recognize them or want to be near them. But a little patience is all that's needed to help your pup overcome missing dog syndrome.

Respect their boundaries

Pushing your dog's boundaries can actually worsen the situation. The more pressure and discomfort they feel, the more likely they are to retreat further and struggle to trust you.
It's important to read your dog's body language and let them have the time and space they need to fully relax. Without the opportunity to relax, they will remain in fight-or-flight mode.
Some important pointers for a distressed dog's body language include:

Rigid body

Baring teeth

Puckered lips

Squinting eyes

Tail down

Body lowered

Ears back

🤓
Expert Insight: While all you want to do will be to give them a big cuddle, it's definitely worth waiting until they are settled back into their normal self. Without considering this, you put yourself and your dog in danger.

Create a safe space

Your dog's instinct will be to hide, and if they don't have a safe space to retreat to, their stress levels and fear will increase. Choosing one room dedicated to your dog's rest and recovery is essential for their wellbeing. In this room, make sure you:

Provide hiding places: Ensuring there are plenty of nooks and crannies that your dog can squeeze into can help them regulate their stress and fear. Under beds, cardboard boxes, and covered dog beds can all be great options.

Put your dog's favorite toys in there: Your dog's favorite toys will smell like home and can help comfort and relax your pup and trigger their memory, helping them return to their normal state.

Provide familiar-smelling blankets and clothes: Scent is very important to our pups, and the most comforting smell will be of their territory and pack. That's you! So blankets, clothes, and bedding are a good way to relax your pup and remind them that your home is safe.

Provide food and water: Your dog's survival instincts will be telling them to find food and water, so to calm them down, ensure there is fresh food and water available. You can also offer a few of your pup's favorite treats!

Choosing one room dedicated to your dog's rest and recovery is essential.

Keep the house calm and secure

A safe and secure environment is essential for helping your beloved dog overcome their missing dog syndrome. To make your home a relaxing and welcoming environment, do the following:

Don't have visitors over: Introducing more people into your dog's territory, especially strangers, is a surefire way of adding to their stress. For a few days, or until your dog is back to normal, ensure only family are in the house.

Keep noise levels down: Loud noises can startle your pup and trigger their survival mode. To prevent this, avoid playing loud music, having construction work done, and hosting parties.

Don't have other pets in the house: Other pets and animals create a stressful environment for your dog. Not only will they have to avoid the people in the house, but they will also want to avoid the pets, making it difficult for them to feel safe and comfortable. Keep existing pets in a separate room.

Keep doors and windows closed: Because your dog's fight-or-flight instinct is still triggered, they may try to escape again. This is the last thing you need! Be sure to keep the house secure and block any potential escape routes.

Give them all they need

To stop your dog from panicking and to help them relax, you should try to anticipate their needs and meet them all. This will also help destress your pup. Make sure they have:

Fresh food and water

Toys

A dog bed

Company when they want it

Space when they want it

Their grooming needs met

💡
Top Tip: It's important you observe your dog's behavior during this time. Any changes are important to note and it's essential you take them to the vet as soon as they need more attention.

Physically search for them

The most effective way to find a lost pet is through a thorough physical search. It's unlikely your dog has gone too far away from where you last saw them, so it's possible you'll be able to locate them.
Try the following tips:

Bring treats, toys, and blankets: The strong smell of their territory on their toys and blankets can help your dog find you. Similarly, the smell of their favorite treat is likely to lure them back to you!

Check quiet places: Your dog has likely found an isolated and quiet place to hide from potential predators and other people, so be sure to check abandoned buildings, sheds, garages, and bushes.

Check your neighbors' backyards: If your pup disappeared from your home, it's likely they haven't gone too far. Thoroughly searching your neighbor's backyards and even houses is a good place to start!

Search at dawn and dusk: It's much more effective to search at quieter times of the day, as it's more likely your dog is out and about and exploring.
