Dogs can be jealous too!! Tests were made and carried out in Austria. They experiment with 2 dogs and owners. There are 2 ways and the first one works like this:

Both of the dogs will be rewarded with food if they hold out their paws, allowing their owners to shake them. If 1 dog did, and the other did not, the one with nothing will feel sad.

The second way is that the dogs will be separated they'll do their tasks alone. Then, the dogs will then shake their owner's hand continuously, even though there'll be nothing as a treat...

By doing this experiment, scientists can prove that dogs can sense if they are treated unequally.

Sometimes, it may happen due to the relationship between dogs and their owners.

Dogs get jealous like we do!! We are similar in a lot of ways!!!!
