How can I tell if my dog's weight is healthy?

It's important to know what a healthy body weight looks like for your dog from a young age. It's easy to check at home while you are simply observing and petting your dog and referring to a body condition score chart is a helpful way to assess it. Regularly checking your dog's body condition score and body weight allows you to identify weight changes quickly making it easier for you to act in partnership with your veterinarian and help your dog achieve and maintain a healthy weight.

Regularly weighing your dog on a scale is an important monitoring tool that will help you to detect small weight changes before they become visible, but this method alone doesn't tell you if your dog has a healthy body composition.

A body condition score helps to estimate how much body fat a dog has, through simple touch and visual assessment of their shape.

Typically, a dog body condition score is used by veterinarians to evaluate whether your dog is under (too little fat), over (excessive fat) or at (a healthy amount of body fat) their ideal body condition. 

How to use a body condition score

Body condition score is typically assessed using a 9-point system. Scores range from 1, indicating your dog is severely underweight, to 9 at the other end of the scale, which indicates severe obesity.  

The ideal body condition score for a dog, is 4 or 5 on the 9-point system. For a dog to score a 4 or 5 this means you can easily feel their ribs, identify a visible waist from above and can see their abdomen tuck up behind their rib cage when looking at your dog from the side. 

 

Assessing your dog's body condition score

Follow our easy-to-use dog body condition score strategy below to understand whether your dog is underweight, overweight or at an ideal weight.

Step 1 - Look

When assessing a body condition score, look at your dog from above and from the side. Compare their body shape against those highlighted under each score, from 1 to 9, to see which best matches your dog's physical appearance.

Step 2 - Feel

Using your fingers, feel over your dog’s ribs while gently applying a small amount of pressure. You should be able to easily feel the ribs of a dog with an ideal body condition. If you are struggling to feel their ribs without applying a significant amount of pressure this could be a sign that the dog is overweight.

Step 3 - Weigh

Check your dog's weight on an appropriate scale. Along with their body condition score, body weight is a valuable piece of information about the health of your dog. Your veterinarian will be able to address your dog's nutritional needs based on their current and ideal body condition.

It's great news if your dog is already an ideal and healthy weight, and you should aim to maintain your healthy feeding habits. Continue to feed your dog the correct portion sizes, avoid giving them too many treats and ensure they receive daily exercise as recommended by your veterinarian. Keeping on top of these factors will help your dog's weight remain stable.

As your dog ages, remember that feeding and exercise habits may need to be adapted. Regular check-ups with your veterinarian will provide opportunities to discuss changes to your dog's diet and how their activity levels should be altered.
