Does your dog bark non stop when you are not home? Do they get nauseated during car rides? Is your dog scared of loud noises such as fireworks or thunderstorms? If yes, then these are signs of anxiety. Just like humans, dogs too experience anxiety; and when left unchecked it can affect the overall quality of your dog’s life. Even if you think that your dog’s behavior is manageable in the beginning, it’s not likely to improve without help.
