Why a Healthy Weight Matters: Add Years to Your Pet’s Life

Did you know an estimated 60% of dogs and cats are consideredoverweight or obese in the US? While those extra pounds might seem harmless, or even cute, the truth is that carrying excess weight puts your pet at increased risk of serious chronic illness and candrastically shorten their life.

The Health Risks of Pets Being Overweight:

Overweight pets face a higher risk of:

  • Diabetes
  • Arthritis and joint pain
  • Heart and respiratory disease
  • Certain types of cancer
  • High blood pressure
  • Kidney disease

And the consequences go beyond health issues. Studies show:

Weight Isn’t the Only Number That Matters

Just like humans, two pets of the same breed and weight can have very different health profiles. Instead of focusing only on the number on the scale, veterinarians recommend assessing your pet’s Body Condition Score (BCS).

It's a standard visual system that looks at body shape and fat distribution. It’s a more accurate measure of overall health than weight alone, and it can help catch early signs of unhealthy weight gain or loss. This is why Body Condition Score is a better indicator of whether your pet is at a healthy weight.

Here are helpful visual guides:

Research Confirms the Risk: BCS and Lifespan in Dogs & Cats

A 2023 study in Frontiers in Veterinary Science analyzed the relationship between Body Condition Score (BCS) and life expectancy in dogs and cats. This study used a5-point BCS scale, but it is the same principle as the more common 9-point scale, where:

  • 1 is very thin
  • 2 is thin
  • 3 is ideal
  • 4 is overweight
  • 5 is obese

The study tracked lifespan based on BCS in both dogs (Chart A) and cats (Chart B):

What the data shows:

  • Dogs and cats with a BCS of 3 consistentlylived longer across all age groups.
  • Even pets with a BCS of 4 (overweight) had reduced lifespan.
  • Pets with a BCS of 5 (obese) had theshortest life expectancy, regardless of age.
  • The trend held true regardless of the age at which pets were assessed.

These findings make one thing clear: Maintaining a healthy body condition is one of the most powerful things you can do to help your pet live a longer, healthier life.
