- According to the Association for Pet Obesity Prevention's 2022 report, 59% of dogs and 61% of cats in the U.S. are considered overweight or obese
- To check if your dog is overweight, run your hands along their ribcage — you should be able to feel the ribs with a light touch through a thin layer of fat, and your veterinarian can determine a Body Condition Score (BCS) for a more precise assessment
- Spayed or neutered dogs are generally at higher risk of obesity than intact dogs due to the effects of sex hormones on metabolism
- Obesity increases the risk of diabetes mellitus in dogs because excess weight can lead to insulin resistance, where cells do not respond effectively to insulin, resulting in elevated blood sugar levels
- Signs of diabetes in dogs include increased thirst, frequent urination, weight loss despite a good appetite, lethargy, exercise intolerance, and higher risk of infections
- Obesity strains the cardiovascular system and can lead to hypertension (high blood pressure), congestive heart failure, and atherosclerosis (thickening of the arteries)
- Underlying glandular conditions including Cushing's disease (overproduction of corticosteroids from the adrenal glands) and hypothyroidism (underfunctioning thyroid glands) can contribute to weight gain and increase diabetes risk
- A 5-step weight management plan includes tailoring nutrition with veterinary guidance and portion control, regular exercise matched to breed and energy level, mindful treat giving with low-calorie options, proper hydration and vet-approved supplements, and lifestyle changes with family involvement and progress tracking

Pet obesity is a growing concern. According to the Association for Pet Obesity Prevention's 2022 report, 59% of dogs and 61% of cats in the United States are considered overweight or obese. Dog obesity can affect overall health and longevity, but with the right approach you can help your dog reach and maintain a healthy weight.

Is My Dog Overweight?

Healthy Weight for Different Dogs, Breeds, and Sizes

Dogs come in all shapes and sizes, and there is no single standard for ideal weight. Breed, age, and spay/neuter status all influence what a healthy weight looks like. Spayed or neutered dogs are generally at higher risk of obesity than intact dogs, because the absence of sex hormones can affect metabolism. Making weight assessment part of your regular routine helps catch changes early, and your veterinarian can provide guidance at regular check-ups.

How to Visually Assess Your Dog's Body Condition

A simple hands-on check can help determine if your dog is carrying excess weight. Run your hands along their ribcage — you should be able to feel the ribs with a light touch through a thin layer of fat. If you need to press harder to locate them, it may be time to take action.

Determining Overweight Status

Body composition matters as much as weight. Muscles, bones, and fat all contribute to a dog's overall weight, and your veterinarian can help determine whether your dog is within a healthy range. Ask your veterinarian to assess your dog's Body Condition Score (BCS) to establish a goal for weight management. The WSAVA Global Nutrition Committee's BCS chart is a helpful reference for understanding your dog's body condition.

Risk Factors for Diabetes in Dogs

An obese dog is at significantly higher risk of developing diabetes mellitus. Excess weight can lead to insulin resistance, a condition where the body's cells do not respond effectively to insulin. This results in elevated blood sugar levels and can eventually lead to diabetes.

How Does Excess Weight Affect Insulin Sensitivity?

Insulin allows sugar to enter cells for energy. Excess weight can reduce cell responsiveness to insulin, meaning sugar cannot enter cells effectively and blood sugar levels rise. Managing your dog's weight helps maintain normal insulin function.

Recognizing the Signs of Diabetes in Dogs

Symptoms of diabetes in dogs include increased thirst, frequent urination, weight loss despite a good appetite, and lethargy. Additional signs include exercise intolerance and higher risk of opportunistic infections such as urinary tract infections. If you notice these signs, consult your veterinarian for a thorough assessment.

Is My Overweight Dog at Risk for High Blood Pressure?

Excess weight can strain the cardiovascular system, leading to hypertension (high blood pressure). Underlying glandular conditions can also contribute to weight gain and increase diabetes risk.

Cushing's disease is associated with overproduction of corticosteroids from the adrenal glands, which increases blood sugar levels and causes the pancreas to produce more insulin. Hypothyroidism is caused by underfunctioning thyroid glands, leading to reduced thyroid hormone levels that help maintain metabolism and healthy body condition.

Impacts of High Blood Pressure on Overall Health

High blood pressure strains the heart, burdens blood vessels, and can lead to organ damage. Managing your dog's weight helps reduce cardiovascular strain and lower the risk of related health issues.

Monitoring Blood Pressure with Regular Vet Check-Ups

Regular veterinary visits include blood pressure measurements that provide insight into cardiovascular health. These check-ups allow early detection of abnormalities and help you take proactive steps.

Heart Disease Caused by Dog Obesity

When a dog carries excess weight, the heart must work harder to pump blood, causing unnecessary strain. Conditions like congestive heart failure and atherosclerosis (thickening of the arteries) can be worsened by obesity. Heart disease caused by excess weight reduces the heart's ability to transport oxygen and nutrients and clear metabolic wastes, leaving dogs fatigued and less active.

5 Ways to Help Your Dog Lose Weight

1. Tailoring Nutrition

Diet is the foundation of weight management. Consult your veterinarian to develop a diet plan tailored to your dog's breed, age, spay/neuter status, activity level, and health concerns. Use a kitchen scale or metric measuring cup for accurate portion control, and stick to a consistent feeding schedule to support digestion and metabolism. Weight management dog foods are formulated to provide essential nutrients while reducing caloric intake — discuss with your veterinarian whether this option is appropriate.

2. Regular Exercise

Physical activity supports both physical and mental health and is one of the most effective strategies for weight management. Different breeds and energy levels require different amounts of activity — high-energy breeds benefit from vigorous play, while more sedentary dogs do well with walking and lower-impact activities. Activities like fetch, tug-of-war, puzzle toys, hiking, and swimming all help burn calories and provide mental stimulation. Gradually increase activity levels to give your dog's body time to adjust and reduce the risk of strain or exhaustion.

3. Mindful Treat Giving

Treats can contribute significantly to caloric intake. Opt for low-calorie options, and ask your veterinarian about whole food alternatives like lean meats, fruits, and vegetables, which provide protein, fiber, and nutrients with fewer calories than many commercial treats. Use verbal praise and play as alternative forms of reward, and designate specific times for treats so they remain a supplement rather than a primary food source.

4. Hydration and Supplements

Adequate hydration supports metabolism and overall bodily functions. Keep fresh water available at all times, especially during and after physical activity.

Some supplements support joint health, which is especially important for overweight dogs who may experience joint strain during exercise. YuMOVE Advanced Vet Strength Hip & Joint Chews provide targeted support for dogs with higher joint health needs, helping maintain comfortable movement during a weight loss program. For general daily joint maintenance, YuMOVE Tasty Health Bites offer everyday support. Explore the full YuMOVE collection for additional options.

When introducing any new supplement, start with one at a time and follow the dosage guidance on the label based on your dog's weight. Consult your veterinarian before adding supplements to your dog's routine.

5. Lifestyle Changes and Monitoring

Involve the entire family in your dog's weight management plan and make sure everyone follows the same feeding and exercise routines. Track your dog's progress with regular weigh-ins and body condition assessments, and celebrate milestones along the way. Positive reinforcement and consistent routines help make weight management sustainable for both you and your dog.

Addressing dog obesity is about improving quality of life and ensuring your dog has the energy and comfort for daily activities. Work with your veterinarian for personalized guidance throughout your dog's weight management journey.

Frequently Asked Questions

How can I tell if my dog is overweight?

Run your hands along your dog's ribcage. You should be able to feel the ribs with a light touch through a thin layer of fat. If you need to press harder to locate them, your dog may be carrying excess weight. Ask your veterinarian to determine your dog's Body Condition Score (BCS) using the WSAVA Global Nutrition Committee's BCS chart for a more precise assessment. Factors like breed, age, and spay/neuter status all affect what a healthy weight looks like for your specific dog.

What health risks does obesity cause in dogs?

Dog obesity increases the risk of several serious health conditions including diabetes mellitus from insulin resistance, hypertension (high blood pressure), congestive heart failure, and atherosclerosis (thickening of the arteries). Excess weight strains the cardiovascular system and reduces the heart's ability to transport oxygen and nutrients. Obesity can also worsen joint problems and reduce overall energy and quality of life.

Can obesity cause diabetes in dogs?

Yes. Excess weight can lead to insulin resistance, where the body's cells do not respond effectively to insulin. This results in elevated blood sugar levels and can eventually lead to diabetes mellitus. Signs of diabetes in dogs include increased thirst, frequent urination, weight loss despite a good appetite, lethargy, exercise intolerance, and higher risk of infections such as urinary tract infections.

Does spaying or neutering affect my dog's weight?

Spayed and neutered dogs are generally at higher risk of obesity than intact dogs. The absence of sex hormones can affect metabolism and energy levels. This makes monitoring weight and adjusting diet and exercise even more important after spaying or neutering.

What is the best way to help my dog lose weight?

A comprehensive approach includes five key strategies: tailor nutrition with veterinary guidance including portion control using a kitchen scale or measuring cup, provide regular exercise matched to your dog's breed and energy level, practice mindful treat giving with low-calorie options like lean meats and vegetables, ensure proper hydration and discuss supplements with your veterinarian, and make lifestyle changes with family involvement and consistent routines. Gradually increase activity levels to avoid strain, and consult your veterinarian before making significant dietary changes.

What underlying conditions can cause weight gain in dogs?

Glandular conditions can contribute to weight gain and increase diabetes risk. Cushing's disease involves overproduction of corticosteroids from the adrenal glands, which increases blood sugar levels and causes the pancreas to produce more insulin. Hypothyroidism is caused by underfunctioning thyroid glands, leading to reduced thyroid hormone levels that help maintain metabolism and healthy body condition. Both conditions require veterinary diagnosis and management.
