While a vet should tell you if your dog is overweight or obese, there are some telltale signs that will tell you. The most obvious sign of an overweight or obese dog is a lack of a waist (between hips and ribcage), giving them a rounded, barrel-like look. If your dog is more than a few pounds overweight, the hips and ribcage will be completely invisible.
The second sign is inactivity, especially in breeds that enjoy exercising and have naturally higher levels of activity. Dogs are playful by nature, even breeds that don’t necessarily love running around all day. If your dog is too lazy for exercise or struggles to make it down the street without being exhausted, your dog might have a weight problem.
Another sign of overweight problems or obesity is diet. How much are you feeding your dog? Does he or she get a lot of people’s food or dog treats? These are a few of many questions you’ll have to answer if you suspect your dog is overweight. Many dog owners don’t know that they’re most likely overfeeding their dogs, so it’s crucial to feed your dog a diet that reflects his or her body size and activity levels.
