Carrying a few extra pounds might seem harmless, even cute—but for pets, those added pounds can lead to a shorter, less comfortable life. Pet obesity is a growing concern in veterinary medicine, increasing the risk of arthritis, diabetes, heart disease, and even cancer.

At Arcata Animal Hospital, we believe in helping your pets live longer, happier lives through proactive care—and that starts with managing their weight. In this guide, we’ll explain the impact of obesity, how to spot it, and practical steps to help your pet stay healthy and mobile for years to come.

Why Pet Obesity Is a Serious Health Risk

Just like in people, excess weight puts added stress on every part of a pet’s body—from joints and organs to energy levels and emotional well-being.

Health Issues Linked to Obesity:

  • Joint pain and arthritis
  • Reduced mobility
  • Increased risk of diabetes (Not So Sweet: Diabetes in Pets)
  • Heart and respiratory problems
  • Skin conditions
  • Decreased lifespan

The good news? Pet obesity is highly manageable and often reversible with the right plan.

How Do I Know if My Pet Is Overweight?

Many pet parents don’t realize their pet is overweight because weight gain happens gradually—and can be hard to see through thick fur or over time.

A Body Condition Score (BCS) assessment at your pet’s next check-up can help, but you can also look for signs like:

  • A lack of a visible waistline
  • Difficulty feeling ribs without pressing
  • Slower movement or reluctance to jump
  • Panting more easily after activity

How Much Should I Feed My Pet?

Feeding guidelines on pet food packaging are just a starting point. Many pets need fewer calories than listed, especially if they are spayed/neutered or less active.

1. Check the can or bag. How much does it say to feed for your pet’s weight?
2. Consider your pet’s lean weight. The amount you feed should be targeting the lean weight, not their actual (slightly chubby) weight.
3. Use the Pet Calorie Calculator and double check that your calorie goal is correct.
4. Don’t forget to subtract out your normal amounts of treats or other little extras your pet gets through the day. Those calories add up fast!
