When watching a dog sleep, there's nothing more adorable when their paws twitch as they mimic running or they let out a tiny bark.
As owners, we would like to think they're dreaming about snugging up with us on the sofa or running in an open filed surrounded by their four-legged friends.
To answer everybody's questions, Dr Deirdre Barrett, a clinical and evolutionary psychologist at Harvard Medical School, has released a study about what dogs dream about.
She said it is likely dogs dream about their everyday experiences, just like humans, meaning there's a good chance they are dreaming about their owners.
She told People : “Humans dream about the same things they’re interested in by day, though more visually and less logically. There’s no reason to think animals are any different.

"Since dogs are generally extremely attached to their human owners, it’s likely your dog is dreaming of your face, your smell and of pleasing or annoying you.”
Although there's no way to know for sure what a dog is dreaming about, Dr Barrett says it is likely they are dreaming about running when their paws or legs begin to twitch or interacting with another dog or human when they start barking.
She says most animals have similar sleep cycles to humans, going through light, deep and REM sleep stages.
It is during REM (Rapid Eye Movement) sleep when dreams occur for humans, making this the best guess as to when other animals would also experience dreams.
In humans, REM sleep typically begins 90 minutes into a nap and last between five to 15 minutes, with each cycle getting longer throughout the night.
Dr Barrett says owners can try to improve their dog's dreams by exposing them to "happy daytime experiences" and providing them with a safe and comfortable environment to rest on a night.
But when it comes to nightmares the American Kennel Club advises owners to "let sleeping dogs lie" because they could react aggressively towards the person who wakes them up.
A statement reads: " Not all human dreams are good. We infer that dogs can have nightmares, too. These nightmares are hard to watch.
"It can be tempting to wake your dog to comfort her, as you would a child, but there are some risks associated with doggy nightmares that you should share with your family.
"If you’ve ever been woken from a scary dream, you know that it can take a minute to remember where you are and whom you are with.
"Like some people, dogs can react aggressively toward the person waking them. This can be dangerous, especially for children.
"The best thing that you can do for a dog you think is having a bad dream is to wait for your dog to wake up and be there to comfort him."
