Does your dog's whole body wiggle when you come home? A loose, wiggly body—sometimes including the entire back end—is a classic sign of excitement and positive emotion.
If your dog chooses to rest near you, follows you around or checks in with you regularly, it may reflect attachment and social comfort.
A consistent appetite, normal energy and enthusiasm for everyday activities can be positive signs—but appetite changes should not be ignored.
A happy dog doesn't have to be constantly excited. Sometimes happiness is simply feeling safe, comfortable and connected to you.
