Whether it is classified as bipolar or by some other name, yes, dogs can be depressed in many forms. Some dogs can miss their owners so much they will become lethargic, chew their paws, their hair may fall out or they may chew at their fur and have patches missing. It is important that ANY dog gets lots of loving and lots of exercise. Generally when a dog becomes aggressive and moody in nature there is a physical cause for it. Example: My next door neighbors had a Golden Retriever pup and I gave the pup it's first toy. I would go over and play with the pup right up until it became an adult. Without warning the dog became extremely aggressive in nature and would bite. I refused to go over to visit because of the dog. Most owners will say 'Oh he/she won't bite' but no one knows their pet that well and I knew this one would. The owners treated the dog well. When the dog was 10 it had to be put to sleep and it turned out the dog had a cancerous tumor on the brain.
