A few extra pounds on your pet might not seem like a big deal—maybe even a little cute. But in reality, excess weight can quietly take a serious toll on their health, energy, and quality of life.

Obesity is one of the most common health issues affecting pets today, and it often goes unnoticed until it starts causing real damage. Let’s break down what pet obesity really means—and why it’s something every pet owner should take seriously.

Just how common is pet obesity?

According to a 2025 study of over 4.9 million dogs and cats, 52.9% of dogs and 61.1% of cats in the U.S. are classified as overweight or obese (ScienceDirect, 2025). These numbers line up with data from the Association for Pet Obesity Prevention, which also reports that more than half of U.S. pets are carrying extra weight (APOP, 2022).

Despite how common it is, many pet owners still don’t realize when their pets are overweight—meaning the risks often go unnoticed until they start to impact quality of life.

Why extra weight is more dangerous than it looks

Joint damage and arthritis

Every additional pound increases stress on your pet’s joints—especially knees, hips, and the spine. Over time, this leads to chronic joint inflammation, arthritis, and reduced mobility. If your pet is limping, struggling to get up, or no longer enjoys walks or play, weight could be a factor.

Heart disease and breathing problems

Overweight pets are at a much higher risk of heart conditions and respiratory issues. Fat around the chest and abdomen can compress the lungs, making it harder to breathe, especially during activity or sleep.

Diabetes and metabolic disease

Pets with obesity are far more likely to develop type 2 diabetes, which can require insulin treatment and ongoing medical care. This disease is particularly common in overweight cats.

Reduced lifespan

This one’s hard to hear, but it’s important: studies show that overweight pets may live up to 2.5 years less than their healthy-weight counterparts. That’s a lot of missed fetch sessions, snuggles, and adventures.

Energy, mood, and behavior changes

Excess weight doesn’t just affect physical health—it drains your pet’s energy. Many overweight pets become more lethargic, moody, and less interested in play. What seems like “just getting older” might actually be a side effect of weight gain.

Could there be something else going on?

While overfeeding and treats are common culprits, obesity can also be a symptom of an underlying health issue. Conditions like hypothyroidism, Cushing’s disease, or even certain medications can cause unexpected weight gain.

That’s why we recommend speaking with your vet if your pet seems to be gaining weight without a clear reason. Every pet is different, and it's important to rule out anything more serious going on beneath the surface.

Quick at-home checks you can do

Wondering if your pet might be overweight? Here are a few simple things you can check:

Ribs: You should be able to feel (but not see) your pet’s ribs without pressing hard.
Waistline: Viewed from above, there should be a visible waist behind the ribs.
Belly tuck: From the side, the belly should tuck upward behind the ribcage, not hang down.

These quick checks are helpful, but a professional weigh-in gives a much clearer picture of your pet’s body condition.

A couple of ways to start helping at home

We always recommend talking to your vet before making any major diet or exercise changes. That said, here are two simple steps that can make a difference:

Watch the treats. Treats should make up no more than 10% of your pet’s daily calories. Table scraps, especially fatty or sugary ones, are a big contributor to weight gain.
Move a little more. A few extra minutes of walking or playtime each day adds up. Cats benefit from toys that mimic hunting; dogs love short, frequent walks.
