Do Dogs Remember Each Other?

do dogs remember each other

Dogs have amazing memories. They’re smarter than we often give them credit for, and they can remember more than we think. So, do dogs remember each other? Believe it or not, they do.

Do Dogs Remember Their Mother And Their Siblings?

All dogs remember their mother and their littermates. So even though puppies are often separated from their mother and each other at eight weeks old, they’ll retain their mother.

The puppies will remember their mother, but they’ll not forget everything their mother taught them. Instead, they’ll remember all of this for the rest of their life.

On the other hand, puppies may forget their littermates over time. However, if they see their siblings often enough, they may remember that they were from the same litter. 

Dogs mostly remember people, places, and events based on smell. So, if they haven’t seen their littermate in a while, they might recognize them by their scent.

However, if you allow your dog to meet with their siblings often enough, your dog will soon recognize them by scent and react to their name, getting excited to see them.

For example, if you bring your dog to the dog park or doggy daycare regularly (once or twice a week), they’ll surely remember certain dogs that they see there.

Do Mothers Remember Their Litters?

Yes, mother dogs remember their litters. However, they’ll only remember their puppies for up to two years.

Unless the puppies visit their mother often, the mother will forget about her puppies over time.

It’s not known why this happens. It could be because they have multiple litters, or it could be because of the time lost.

Also, puppies are separated from their mothers two months after birth. So, they don’t get a whole lot of time together, to begin with.

Do Dogs Remember Other Dogs They Pass By Daily?

Unless you allow your dog to stop and sniff the other dog for a minute or two, your dog most likely won’t remember other dogs you happen to pass by while taking a walk.

Again, dogs remember most things by scent. So, if you happen to take a walk at the same time as your neighbor every day, then your dog will see the other pup and think they’re seeing the other dog for the first time.

This is why they may bark and react upon seeing the other dog.

If you allow the two of them to get to know one another for a minute or two by sniffing each other, they’ll get a good idea of the other dog’s scent.

So, the next day, if you go on a walk and meet that dog again. Your doggo will slightly remember them. Let them sniff each other for another minute or two, and eventually, the two dogs will recognize each other every day. 

Signs That Dogs Recognize Each Other

Dogs can communicate in many ways. First, of course, they bark and growl, but they also share using body language with each other. 

If your pup recognizes a doggy friend, whether it’s at the dog park or you’re going on a walk, then they’ll show their excitement in a few ways.

For instance, some of the body language that dogs will show off are as follows:

  • Whining (because they can’t contain their excitement)
  • Jumping up
  • Wagging their tail
  • Sniffing the other dog
  • Ears up
  • Spinning around
  • Rolling on their belly
  • Excited behavior
  • The dogs begin to play together (for example, they’ll play bow to each other)

On the other hand, if they recognize the dog but they’re not friendly with each other, there are other signs that they’ll show. 

For instance, they might whine nervously. They may put their tail between their legs, or their ears may go down.

You Can Train Your Dog To Remember Other Dogs

Of course, you can’t make it so that your dog likes certain other dogs. You also can’t control what they can and can’t remember. However, you can help train them to recognize certain dogs.

For example, if you’re going to have another dog at your home for some time, you can train your dog to get used to their scent before they come over.

The way you can do this is:

  • Bring over a blanket or toy that belongs to the other dog so your pup can sniff it and get used to the scent
  • Meet the other dog with your pup on a walk in a neutral area so they can get reaquantined 
  • Bring them both to the dog park and allow them to get to know each other
  • Praise both dogs whenever they’re excited to see one another

When letting dogs remember each other, you’ll want them to see each other regularly. For example, you can set up puppy playdates once a week or every other week. Once your dog goes a month without seeing their friend, they may forget about them. 

Dogs Can Be Great Friends With Each Other

So, it can be a hit or miss if a dog remembers another dog. However, if they recognize the scent and get close to the dog and their smell often enough, they’ll remember each other.
