For a long time, it was believed in scientific circles that dogs were incapable of experiencing complex human emotions due to their limited development.
However, reality does not quite fit with this theory.
Surely many owners have learned from their own experience that dogs sometimes behave in very strange ways.
Despite the fact that jealousy is usually considered a complex emotion, dogs have the ability to experience it. Experts note that this is due to many factors.
First of all, it is worth noting that we begin to get to know and care for the pet mainly from an early age. As a result, the dog begins to perceive the owners as parents. And such loved ones cannot be "shared" with anyone else. Therefore, it is not surprising that the dog is not embarrassed to demonstrate jealousy and fight for the love of a loved one.
Sometimes animals can fight for their love for their owner very actively, which causes a lot of inconvenience. For example, a dog can hinder new relationships, demonstrating disrespect for the chosen ones and trying to drive them away in every possible way.
Dogs can also be jealous of other animals - in this case, the dog may even bite your new pet.
If jealousy causes obvious inconvenience, then it should not be encouraged. Sometimes a jealous pet seems funny and cute, but you cannot "praise" for bad behavior.
Try to demonstrate to the animal the fact that you are the main one in your relationship.
