Dogs always seem happy as long as they are around their owners. It looks like you can go anywhere with your dog and he will still feel at home. This, however, isn’t always the case. Dogs, just like humans, get homesick. Our furry friends are creatures of routine and habit. Disrupting their routine might have some adverse results in their behavior. They also tend to get used to the smells, sounds, and visuals around them. They might even get attached to a favorite toy. One of the common triggers for homesickness in dogs is traveling. Spending too much time away from home might cause your dog to start missing home. Leaving your dog at a dog sitter’s house might also bring homesickness to the pooch.
