Looking at your dog from above, if you notice that the pup looks rather rotund and oval-shaped, it's likely that your dog is fat. If, on the other hand, you notice that your dog has a defined waist toward the rear and a straight build down the sides, then they're probably at a healthy weight.
How do I know if my dog is at a healthy weight?
Ideally you will be able to see its waist tucked behind the ribs. If you can see the outline of your dog's individual ribs and the waist is noticeably more narrow than its ribcage, then your pet is underweight; however, if the waist is in line with the ribs or bulges out past them then it is overweight.
How can you tell if your dog is overweight or underweight?
Stand your canine chum up and run your hands over their sides. If you can't feel their ribs – or if you can't feel them very well – there's too much fat and you have an overweight dog. If there's too much rib, i.e. you can't feel much between your dog's skin and its ribs, you have an underweight dog.
