Do Dogs Get Jealous?

Dogs can get jealous when their owner pay attention to another dog, according to scientific research published on PLOS One in 2014. The study observed the behavior of several dogs as their owners focused attention on three different objects: talking sweetly to a stuffed-toy dog that could make sounds and move its tail, a jack-o-lantern bucket, and a children's book that was read aloud. From the study, the dogs exhibited jealousy through more aggressive behavior such as biting towards to toy dog; as well as attention seeking behaviors like getting between the owner and the toy. The study suggests that jealousy is a primal emotion that evolved to maintain social bonds between pack animals.

More about dog behavior:

  • Dogs release the chemical hormone oxytocin, which is released during both love and jealousy expressions.

  • Dogs can develop a phobia of thunder. Symptoms of phobia include pacing, shivering, and drooling during thunderstorms.

  • It's natural for dogs to eat feces as the waste contains protein.

Dog behaviors can be quite interesting, especially considering how some of it models human behavior. For example, though we obviously won't get jealous if our friend has a new stuffed animal, jealousy can derive if they hang out with a friend too much. From our perspective, envy might even derive from our attempt to maintain social bonds with our groups, in the same way that dogs try to maintain social bonds between pack animals.


To be honest, I'm not surprised that dogs can develop a phobia of thunder, as that's perfectly understandable. In my opinion, this is considering how they might even develop the phobia at a young age, as is the case with people too. In fact, have you also noticed that most people have phobias because of something that happened to them during their childhood, myself included? Basically, when we're all growing up, whatever happens to us at a young age shapes us into who we are, directly and indirectly.


Wow, I didn't know that dogs could get jealous, as I certainly find that to be interesting. Also, this is especially in the sense that many don't associate animals to have emotions, at least not on the level of people. However, in this case, dogs are definitely an exception. Not only do they have some of the same feelings that humans have, but even more so, the fact that they can get jealous really shows how much they care about their owner(s).
