People often say that dogs are man’s greatest friend, but they also get quite close to other dogs, especially their moms and puppies.
“Does my dog remember its mother or siblings?” is a question that many dog owners ask.
Yes, but only to a certain point.
Dogs use their sense of smell and their past experiences to remember things. The American Veterinary Society of Animal Behavior says that pups who spent more time with their families, especially between the ages of 2 and 16 weeks—when they were most likely to socialize—will remember them better.
Let’s talk about how dogs recognize their family, what influences their memory, and what this means for your pet.
A QUICK LOOK
- Dogs can recognize who is who in the family by their smell. Their nostrils can remember smells for a long time, especially their mothers’.
- The strongest ties are between the mother and the pup. Even after a lengthy time apart, dogs usually remember their mothers.
- Siblings forget who they are as time goes on. If puppies are separated before they are 12 weeks old, they might forget each other.
- It’s really vital to get your puppy used to being around other people and animals when they are between 2 and 16 weeks old. This time will stay with you for a long time.
- Dogs remember more than just family ties; they remember relationships. They can remember every person or dog they lived with.
- Science backs this up. Studies of animal cognition have found that dogs spend more time sniffing things they know than things they don’t.
- Your dog sees you as a member of the family. You are their home, secure refuge, and dearest friend.

How Dogs Know Who Their Family Is
1. The Smell: A Dog’s Superpower
Dogs can detect things that we couldn’t possibly think of. People think that their sense of smell is 10,000 to 100,000 times stronger than ours [AKC, 2022]. This is the main way they figure out who they are.
Just like we do with sight, dogs utilize smell to figure out who they are. Dogs can often scent something they know immediately, even if they haven’t seen it in years.

2. The Important Time for Socializing (2 to 16 Weeks)
Puppies make most of their memories and learn how to act for the rest of their lives during the first few months of their lives.
- Puppies learn how to get along with other dogs, how to control their bites, and how to talk to other dogs while they stay with their moms and siblings for at least 8 weeks.
- People get to know each other better and remember fragrances when they stay together for 12 to 16 weeks.
- Dogs that are separated too soon may not be able to recognize their siblings later because they didn’t have enough time to build these early relationships.
This early window is like a “bank” for memories. A dog’s brain retains memories throughout this phase that can change how they recognize things years later.

3. Knowing the Mother and Pup
A dog loves its mama very much. Research shows that mother dogs can still recognize their offspring despite being apart for two years [Applied Animal Behaviour Science, 2001].
Even after they are adults, puppies often remember how their mother smelled. The newborn associated the mother’s smell with safety, food, and warmth as it grew up.
4. Remembering Siblings Over Time
Dogs can tell their siblings apart, but this skill loses over time, especially if they were separated when they were young.
- Puppies that are separated at 8 weeks may forget each other faster than puppies that are kept together for a longer time.
- Dogs who lived with their littermates until they were 16 weeks old are more likely to remember them even years later.
But dogs don’t think about their siblings in the same way that people do. Smell and familiarity, not family ties, help them recognize others.
5. Knowing Other Dogs They Lived With
Dogs don’t just recall their family; they also remember the other dogs they lived with as puppies. If a puppy lived with a foster brother or another adult dog, they will be able to recognize and remember them for a long time.
Things That Can Change a Dog’s Memory
There are a lot of elements that can affect how well your dog remembers family members:
- The Environment and Bonding: A safe, loving, and stable location is excellent for memory. If dogs had fun with their family, they are more likely to remember them.
- The Dog’s Gender: Studies show that female dogs often recognize and prefer both male and female siblings, but male dogs tend to prefer same-sex siblings.
- Experiences in Socialization: Dogs that played with people and other dogs more when they were younger are better at recognizing other dogs, even if they aren’t family.
- Time Away: The longer a dog is away from its family, the less it will remember them. But a smell might still bring back memories after a long time.

In Real Life: Dogs Reuniting with Their Families
There are a lot of moving stories about dogs that remember their families after being apart for years.
One reported case showed that two adult littermates who hadn’t seen each other in more than two years knew each other and were happy and friendly when they encountered each other again [University of Lincoln, UK, 2015].
These anecdotes show how well dogs can detect things. A familiar smell can bring back memories of safety, play, and familial relationships, even if it isn’t smelled often.
What This Means for Your Dog
- To Enable Mothers and Puppies to Know Each Other:
Your dog probably knows its mother, and the mother presumably knows her puppies as well. These two animals have one of the strongest bonds in the world. The scent and early care make it stronger. - To Make Siblings Closer:
Your puppy can forget about its siblings over time if it was taken away from them when it was 8 weeks old.
If they were together until they were 16 weeks old, they might remember their siblings for the rest of their lives. But dogs don’t think of their siblings as family; they think of them as familiar playmates. - For Dogs That Aren’t Related:
Canines can also recall other dogs they lived with during this key phase for the rest of their life. A puppy that lived with a foster sibling or a family pet will always remember them, even if they don’t see them for a long time. - For Owners:
Your dog will never forget you! Dogs have a greater memory for people than family members do. Research indicates that dogs can retain the scent of their owner for years, even following relocation to a different residence [AKC, 2022].
How to Help Your Dog Remember Things and Get Along Better
Want your dog to remember things better and build more connections? You can do this:

- Scent Items: When you leave the house, leave your dog a blanket or toy that smells like you. It will make them feel better.
- Socialization: Let your puppy meet new people, dogs, and locations in the first several months.
- Consistency: Dogs create trust and make solid bonds when they have consistent routines.
