Many owners find it hard to tell whether their pet is at a healthy weight. A few extra pounds can creep on gradually, and pets of the same breed can have very different builds. Veterinarians often use a hands-on method called body condition scoring to assess weight. Learning the basics can help you notice changes between checkups.
What body condition scoring is
Body condition scoring uses sight and touch to estimate how much fat a pet is carrying. A commonly used system runs from 1 to 9, where 1 is very thin, 9 is severely overweight and the middle of the scale, around 4 to 5, represents an ideal condition for many pets. Some clinics use a 1 to 5 scale instead. Either way, the goal is the same: an objective way to describe body shape, rather than relying on weight alone.
How to check your pet at home
Use these three checks, with your pet standing comfortably:
- Ribs: Run your hands along the sides of the chest. In an ideal pet, you should be able to feel the ribs easily with light pressure, under a thin layer of fat, without them being sharply visible. If you have to press hard to find them, your pet may be carrying extra weight. If they stick out prominently, your pet may be too thin.
- Waist from above: Look down at your pet from above. You should see a visible waist behind the ribs, narrowing before the hips.
- Abdominal tuck from the side: Look from the side. Many dogs at a healthy weight have a belly that tucks up behind the ribs. Cats often have a small belly pouch, called a primordial pouch, which is normal and not a sign of fat on its own.
Thick coats can hide a lot, so rely on touch for fluffy pets.
Why a healthy weight matters
Excess weight in pets has been linked to joint problems, including arthritis, as well as diabetes, particularly in cats, breathing difficulties and reduced stamina. Keeping pets lean may help them stay more comfortable and active as they age. On the other hand, unexplained weight loss can signal illness and should be checked by a veterinarian promptly.
Helping your pet reach a healthy weight
If your pet needs to lose or gain weight, work with your veterinarian on a plan. Your vet can calculate a target weight and daily calorie needs, and rule out medical causes. General habits that often help include:
- Measuring food with a measuring cup or kitchen scale instead of estimating.
- Counting treats as part of the daily calories.
- Using part of the daily food for training rewards and food puzzles.
- Increasing activity gradually, with walks for dogs and play sessions for cats.
- Weighing your pet regularly, or stopping by the clinic for weight checks.
Avoid rapid weight loss, especially in cats. Cats that stop eating or lose weight too quickly can develop serious liver problems. Any diet change for a cat should be guided by a veterinarian.
Ask your vet to show you your pet’s score at your next visit. Once you know what ideal feels like, monthly hands-on checks at home become quick and easy.
