Is Your Pet Carrying Extra Weight? Here’s How to Help Them Stay Fit
More than 50% of dogs in the United States today are overweight or obese, increasing their risk of numerous health issues, including skin disease, diabetes, and arthritis.1 Part of the problem is that weight gain is easy to miss. At the same time, confusion around how much to feed and what a healthy weight actually looks like makes overfeeding common. Understanding these blind spots is the first step to helping your dog maintain a healthy weight.
The Heavy Truth About ‘Fat Blindness’
A study led by Texas A&M University and the Dog Aging Project found that weight gain often develops through a combination of breed tendencies, strong food motivation, daily routines, and feeding habits.2 Because the change is so gradual, the extra weight can start to look normal to many loving pet parents. This fat blindness is one of the biggest barriers to addressing weight early.
Before adjusting portions or calculating calories, it’s important to get an honest picture of your dog’s body condition. Veterinarians use the Dog Body Condition Score (BCS) system, which combines what you see with what you can feel.3 You can use these same checks at home:
1. Feel the ribs — You should be able to feel the ribs easily with light pressure, without them feeling sharp or buried under a thick layer of fat.
2. Look for a waist — Viewed from above, your dog should have a visible waist behind the ribs. A round or oval shape often signals excess weight.
3. Check the abdominal tuck — From the side, the belly should slope upward toward the hind legs. A straight or sagging belly usually indicates extra body fat.
On the standard 1-to-9 BCS scale, a score of 4 to 5 is considered ideal. If your dog falls above that range, even by 1 or 2 points, it means excess weight is already adding strain on their body. If you’re unsure, your veterinarian can assess your dog’s body condition and set a realistic, healthy weight goal before you make any changes.
How Many Calories Does Your Dog Need?
Many dogs are overfed without their owners realizing it, which makes understanding calorie needs essential. The first step is identifying your dog’s ideal weight, not their current weight. Your veterinarian can help determine this based on breed, body structure, and body condition score. Once you have that number, you can estimate daily calorie needs using this simple formula:4
Daily calories = body weight (kg) × 30 + 70
To convert pounds to kilograms, divide by 2.2. For example, a 20‑pound dog weighs 9.1 kilograms. Using the formula, that equals roughly 343 calories per day to maintain a healthy weight. Keep in mind this is a starting point, not a fixed rule. Factors like age, activity level, and whether your dog is spayed or neutered can all affect calorie needs.
Don’t Underestimate the Power of Portion Control
Once you know how many calories your dog needs, the next step is controlling how much they actually eat. If your dog’s bowl stays full or mealtimes are inconsistently, you might be unintentionally free feeding, making it difficult to track how much your dog is eating.5
Portion control is one of the most effective ways to manage your dog’s weight, yet it’s often overlooked. Many pet parents rely on feeding guidelines on pet food labels, but those are broad estimates that don’t account for a dog’s individual needs. Putting portion control into practice comes down to consistency and accuracy:
1. Base portions on your dog’s ideal weight, not their current weight, and use the feeding guide as a starting point.
2. Use a level measuring cup or, ideally, a digital kitchen scale to avoid overfeeding.
3. Serve meals consistently, usually two to three times per day, and adjust portions as needed.
Additional Ways to Help Your Pup Slim Down
Along with portion control, these simple habits can further support healthy weight loss:6
- Build in daily movement — Taking longer walks, adding a daily game of fetch, or planning weekend trips to the dog park helps burn calories while keeping things fun.
- Swap high-calorie treats for smarter snacks — Replace calorie-dense snacks with options like crunchy green beans, baby carrots, peas, or small apple slices (no seeds or core). For protein‑loving pets, small amounts of cooked meat or fish work well.7
- Choose non-food rewards — Not every “good job” needs food. Praise, belly rubs, playtime, or a favorite toy can be just as motivating.
Keep in mind that weight loss should be gradual. Losing weight too quickly can lead to health problems, so most veterinarians recommend a steady loss of about 1% to 5% of body weight per month.8 Working with your vet helps ensure the plan is safe and sustainable.
