There are several signs that can indicate if your dog is overweight. These include visibly not being able to feel the ribs easily, having no defined waist when viewed from above, a sagging abdomen, and less visible or no tuck-up (the tuck of the abdomen up into the rear flank area). Additionally, if you notice your dog is less active, tires easily, or has difficulty breathing, these could also be signs of being overweight. It's important to consult with your veterinarian to determine if your dog is overweight and to create a plan to help them achieve a healthy weight.
