Helping Pets Stay in Shape: How to Maintain a Healthy Weight for Cats and Dogs

For many of us, pets are more than companions—they’re family. The deep bond we share with our cats and dogs often finds expression in the way we care for them, especially through food and treats. A tasty snack becomes a symbol of love and a reward for good behaviour, an increased portion of food shows our affection and makes them happy. But in our efforts to reward or spoil them just a little, we may unintentionally put their health at risk. Maintaining a healthy weight is one of the most important things we can do to ensure our cats and dogs live long, active, and happy lives.

Why a Healthy Weight Matters

Being overweight can seriously impact a pet’s health. It increases the risk of diabetes, joint problems, heart and respiratory issues, and can even shorten their lifespan. For cats, excess weight can also reduce mobility and grooming ability. For dogs, it may affect their stamina, behaviour, and overall wellbeing. Keeping pets at an ideal weight not only supports physical health—it helps them feel more energetic and comfortable in their daily lives.

Spotting the Signs: Is My Pet Overweight?

It is crucial to check your pet’s weight regularly, but monitoring a number on a scale might not be enough. Body condition scoring (BCS) in addition to body weight measurement is a quick method that considers your pet’s shape and any layers of fat over their contours, to give you an idea of whether they are underweight, at ideal weight, or overweight. This hands-on and visual check looks at features like the visibility of ribs and waistline. At a healthy weight:

Cats should have a visible waist behind the ribs when viewed from above, and a slight tummy tuck when viewed from the side.
Dogs should have ribs that can be felt (but not seen) easily and a defined waist and abdominal tuck.

Handy visual charts prepared by the World Small Animal Veterinary Association (WSAVA) can guide you in evaluating your pet’s status. If you’re unsure, your vet can help assess your pet’s body condition and provide tailored advice.

Top Tips for Maintaining a Healthy Weight

Feed the Right Amount
Use feeding guidelines on pet food packaging as a starting point, adjusting based on your pet’s activity level, age, and health. Use a scale or measuring cup to stay consistent.
Watch the Treats
Treats should be no more than 10% of your pet’s daily energy intake. Consider healthier options or use part of their daily food ration as treats.
Stay Active Together
Regular activity is essential. Daily playtime for cats and walks or play sessions for dogs help burn calories and strengthen your bond.
Weigh Regularly
Monitor your pet’s weight routinely—monthly is ideal. Small changes can be managed more easily than major weight loss efforts later on.
Choose the Right Food
A complete and balanced diet formulated for your pet’s life stage and lifestyle is key. Light or “weight management” foods can help in some cases, especially for pets prone to weight gain.

Every Pet is Unique

What works for one cat or dog may not be right for another. Always talk to your vet if you have concerns about your pet’s weight or diet. Together, you can create a plan that suits their individual needs.

Helping our pets maintain a healthy weight is one of the most meaningful ways we can care for them. With a little attention and consistency, you can keep your four-legged friend happy, healthy, and full of life.
