Patricia McConnell, PHD, Certified Animal Behaviorist and author of several books related to dog behavior, believes that dogs remember their previous owners, however they don't remember in the same capacity as people do.
The word so far is dogs have short-term memories, but with so much interest in the canine mind, new studies have come to light suggesting our wise woofers have a memory system similar to humans. They call it episodic memory and it means they can remember people theyv'e known in the past.
The American Kennel Club says changing owners can be traumatic for dogs. Losing their owners can make dogs stop eating, lose weight, lose interest in physical activity, and exhibit symptoms of canine depression. That's why you must take any decision to re-home dogs seriously.
Once you get your new fur-baby home, there will be signs of their former life, as being abandoned opens up a well of emotion, and it might take a little while to get some pooches to trust. Imagine being left to wander the streets or navigate life in the Everglades, where other animals make their home.
A dog can remember someone his entire life.
It's safe to say that your dog will not forget you after two weeks, a month, or even if you are gone for many years.
Signs Your Dog Recognizes You After A Long Time Apart. The fact of the matter is that your dog will almost always remember you, regardless of how long you're gone.
Memory Span
"Dogs forget an event within two minutes," reported National Geographic, citing a 2014 study performed on various animals from rats to bees. Other animals have long-term memories, such as dolphins, but dogs don't seem to have a long-term memory that lasts much beyond those two minutes.
The grief of rehoming tends to be layered with emotions such as guilt and shame. You may feel like you'll never forgive yourself for this decision. Giving a pet up for rehoming is never easy and there are very few people who can do this without any misgivings.
Dogs can actually start missing their owners from the moment they part ways, and keep missing them more up until two hours. Beyond two hours, the melancholy stays about the same until they're reunited with us.
Wondering what dogs so when you're not home? Most dogs spend a lot of their time catching some Z's. When you're not home to keep your pet busy, they'll likely find a comfortable place to cuddle up and take a siesta. If you're gone for a longer period of time, your pet might even take a few naps.
Beaver said major changes in a dog's life could lead to periods of depression. Those include moving into a new home, a new spouse or baby in the household, or adding another pet. Even a change in the dog's schedule, for instance a stay-at-home owner who takes a job, can cause a dog to get down.
There are some things we can do to help them settle and feel safe in those first few days. Keep in mind though, that it generally takes about three weeks for a dog or puppy to start to feel 'at home' and to show their true nature.
Getting your dog to trust you can take time, practice, and a lot of consistency. You can expect anything from 2 weeks-2 months for this to happen.
So as long as a dog can smell, has healthy eyes, and can hear, they will most likely remember you no matter how long you've been out of their life. If you are wondering if your dog misses you while you're gone they don't have any knowledge of time but can experience separation anxiety.
"It shows that our dogs remember events much like we do, and [it] blows out of the water the old way that most scientists would characterize animal memory," says Brian Hare, a dog cognition expert at Duke University in Durham, North Carolina, who was not involved in the study.
And “because dogs are highly social creatures,” Dr. Borns-Weil says, in most cases, “getting another dog is the right thing to do. Dogs in isolation are not happy.” Even if you are home with your dog much of the day, a second dog in the family might very well be the right choice.
Dogs spend much of their day snoozing, but in the hours they're awake, they probably spend time thinking about some of the same things that a 2- or 3-year-old child would: “Solving problems, what's for dinner, what's that over there?” Hare says.
They have the same feeling as a child towards their parents and so they are not just an animal but a child to us and for them we are family. If ever you wonder whether your pooch is just like your child or not, think again. For them you are their parents.
It is a heartbreaking situation, as being rehomed can exacerbate separation anxiety for a dog. Sometimes it is the only option. However, as long as a shelter or rescue is aware of the issue, they will do their best to find a foster or adopter who is able to both manage and address the separation anxiety.
When pets are abandoned, they will often be confused about being left behind, removed from the only family or “pack” that they have ever known. Besides the emotional toll, pets can experience severe health impacts from abandonment.
Be gentle with yourself and be willing to forgive yourself.
Accept what you had to do and let it go. Don't dwell on what-ifs. Pet rehoming guilt is real but, you can't change the past or the circumstances that led to this, so keeping it with you and holding onto the guilt will only make you feel worse.
Although dogs can't identify themselves in the mirror, they still have some level of self-awareness and ace other self-recognition tests. They can recognize their own odor, and recall memories of specific events, Earth.com reports.
Can Dogs Tell Time? Dogs have a sense of time but don't understand the 'concept' of time. Unlike humans, dogs don't have the ability to create actual measures of time, like the second, hour, and minute, and they don't know how to read clocks.
Studies have shown many physical and mental health advantages to owning a pet, and co-sleeping increases the amount of time spent with that pet, potentially increasing those benefits. For example, co-sleeping can increase the feelings of comfort and companionship your dog provides.
