How to Manage Your Pet's Weight
Published: May 3, 2026
A chubby pet might look adorable on social media, but pet obesity is a growing epidemic with serious health consequences. Just a few extra pounds can significantly impact a pet's quality of life, leading to arthritis, diabetes, respiratory issues, and a shorter lifespan.
Identifying the Problem
It's often difficult for pet parents to notice weight gain since it happens gradually. Instead of just relying on the scale, use the Body Condition Score (BCS). You should be able to easily feel your pet's ribs without pressing hard, and they should have a visible "waist" when viewed from above. If their back is flat and wide, it's time for a change.
Safe Weight Loss
Weight loss in pets must be gradual. Rapid weight loss, especially in cats, can cause a life-threatening liver condition called hepatic lipidosis. Work with your veterinarian to determine a safe target weight and calculate the exact number of daily calories your pet needs using our free Dog Calorie & Weight Management Calculator (includes BCS body condition scoring and safe weight reduction targets).
Visualize Their Progress
Tracking weight changes manually can be tedious. MaunaPet includes an interactive weight history chart. Simply log your pet's weight periodically, and the app will generate a visual graph, helping you stay motivated and ensuring they are on the right track.
Rethinking Treats
Treats are the usual suspect when it comes to pet weight gain. Treats should never make up more than 10% of your pet's daily caloric intake. Consider substituting high-calorie commercial treats with healthier options like baby carrots, green beans, or small pieces of apple (for dogs), or simply use a portion of their daily kibble as rewards.
Increase Activity
Diet is only half the equation. Increasing daily exercise is essential for healthy weight management. For dogs, this means longer, brisker walks, games of fetch, or swimming. For cats, engage their hunting instincts with laser pointers, feather wands, or puzzle feeders.
Helping your pet maintain a healthy weight is one of the most loving things you can do. It requires patience and consistency, but the reward is a more active, happier companion who will be by your side for years to come.
Frequently Asked Questions
How can I tell if my pet is overweight?
You should be able to feel (but not see) the ribs, and your pet should have a visible waist when viewed from above. If the ribs are hard to feel under a fat layer and the waist is gone, your pet is likely overweight.
How much weight can a dog or cat safely lose per week?
Safe weight loss is gradual — about 1–2% of body weight per week. Rapid weight loss, especially in cats, can trigger dangerous liver problems, so always design a plan with your vet.
Are treats making my pet fat?
Often, yes. Treats should make up no more than about 10% of daily calories. Swapping high-calorie treats for vegetables like green beans or carrots, and measuring meals, makes a big difference.
How do I help my pet lose weight?
Measure portions with a proper cup or scale, cut back on treats, increase daily activity gradually, and track weight over time so you can see the trend and adjust with your vet.
