Dogs howl for a number of different reasons. Sometimes it’s because they’re sad, lonely or sad, other times it’s because they’re hurt.
However, the most common reason why dogs howl is to make their presence known and to bond with other dogs. Which is why when dog howls, others copy them.
This video shows a beautiful dog howling at the TV. The dog in the animated film howls, setting the dog watching the film off howling.
It’s cute, but it also shows how dogs can’t tell the difference between real dogs and animated dogs. Now, I’m not saying dogs are stupid, but you wouldn’t catch a cat doing that.
