How To Tell If Your Dog Is Underweight

The most obvious way to tell if your dog is underweight is to look at their body. If you can see their ribs and their pelvis sticking out, then they are probably overweight. If your dog has longer fur and it is hard to do a visual check, you can feel their ribs and hips, if there is no layer of tissue over their ribs and pelvis and you can feel their skeleton easily, they are probably underweight. There are some other signs too. Your dog’s coat will be matted or dull or their grooming isn’t as thorough. They will also have less energy and avoid exercise and physical activity.
