Canine Overweight Issues: Consequences, Signs, and Weight Management Strategies
Dog Obesity: A Growing Health Concern for Canine Populations
In veterinary medicine, the increased prevalence of canine obesity is a significant cause for concern. According to the Association for Pet Obesity Prevention, nearly 60 percent of dogs are classified as overweight or obese, as revealed from a 2022 national survey (1). This alarming statistic underscores the negative impact obesity can have on a dog's health and lifespan.
Pet owners play a crucial role in managing their dogs' weight, and the recent survey shows that 73 percent of dog owners have implemented weight management strategies (1). Enhancing understanding of why obesity in dogs is a grave concern and learning how to address or prevent this condition are essential for pet parents.
Understanding Dog Obesity
Obesity in dogs refers to an excess accumulation of body fat that negatively affects their ability to lead active, healthy lives. Obese dogs have a body mass index far beyond the ideal range, causing obvious fat deposition across the body. Overweight dogs are typically 10 to 30 percent over their ideal body weight, while obese dogs exceed this benchmark by at least 30 percent (2). This excessive fat accumulation also increases inflammation throughout the body, which can be detrimental.
Causes of Obesity in Dogs
An array of factors can contribute to dog obesity, with underlying health conditions like hypothyroidism or Cushing's disease often implicating weight gain. Inadvertent overfeeding by pet owners, offering too many treats, and insufficient exercise are other common causes. Combining overfeeding with inadequate exercise is a dangerous combination for many dogs.
Certain dog breeds are more susceptible to obesity. According to a recent study, breeds such as Golden Retrievers, Pugs, Beagles, English Springer Spaniels, and Border Terriers have a higher risk of becoming overweight compared to other breeds (3). Middle-aged or older dogs, with their slower metabolisms, also tend to gain weight more easily. Spaying and neutering dogs may increase their risk of obesity, and there may be a genetic component that contributes to a dog's susceptibility to obesity.
Health Risks of Obesity in Dogs
Obese dogs face a heightened risk for numerous health issues, including diabetes, heart disease, cancer, arthritis, high blood pressure, respiratory disease, urinary tract diseases, and skin disorders. A shorter lifespan and reduced quality of life are additional consequences of obesity in dogs. If an underlying medical issue is present, obesity can complicate the management of concurrent diseases.
Identifying Obesity in Dogs
Veterinarians can easily detect dog obesity because of its distinctive appearance. However, pet owners may overlook this condition, emphasizing the importance of annual checkups with a veterinarian. Obesity manifests as a rotund appearance in dogs, obscuring the characteristic hourglass shape seen in dogs at their ideal weight. From the side, there will be obvious fat deposits over the shoulders, ribs, and hips. Additionally, signs of obesity in dogs include an inability to feel or see the ribs, less energy, frequent or heavy panting, and a decreased willingness to exercise or play.
Diagnosing Obesity in Dogs
During a physical examination, veterinarians diagnose obesity by visually inspecting the dog and feeling the ribs to assign a body condition score, either on a scale of 1 to 9 or a scale of 1 to 5, depending on the veterinarian's preference. Scores of 6 or above on the 9-point scale and 4 or above on the 5-point scale are considered overweight or obese. The higher the score, the more body fat a dog has, directly correlating with obesity.
Weight Loss Solutions for Obese Dogs
Veterinarians begin addressing obesity in dogs by discussing feeding and exercise routines, as well as any pertinent medical history that may be contributing to weight gain. Blood tests or other diagnostic tests may be administered to ensure there is no underlying health issue that is causing weight gain. Once medical concerns are ruled out, veterinarians can collaborate with pet owners to develop a tailored weight management plan to help their dog lose weight.
Prioritizing the reduction of treats and table scraps is essential in a dog's diet, along with accurately measuring each meal and feeding only two distinct meals per day. Prescription dog foods specifically designed for weight loss, such as Hill's Prescription Diet Metabolic Weight Management Dog Food or Hill's Science Diet Perfect Weight Dog Food, may also be recommended by a veterinarian.
Exercise is critical for dogs in their weight loss journey. Dogs carrying extra weight should gradually begin a low-impact exercise regimen, such as walking, to burn calories and return to a more ideal weight. Increasing the dog's activity level can help, but be mindful that obese dogs are prone to joint problems, particularly arthritis, so it's crucial to consult a vet before undertaking any new exercise plan.
In some cases, joint supplements containing chondroitin and glucosamine, such as Dasuquin Advanced or Cosequin, may benefit obese dogs by helping maintain joint health while they're shedding pounds. If a dog shows signs of joint pain, the vet may recommend pain medications like Galliprant or Carprofen. As always, consult a veterinarian before embarking on any exercise or weight loss regimen for your dog.
Preventing Obesity in Dogs
Preventing obesity in dogs can be achieved by offering regular daily exercise opportunities, measuring every meal, limiting treats, feeding a nutritious diet, and scheduling routine veterinary checkups. By making small changes each day, pet parents can ensure their dogs maintain a healthy weight, enhancing their overall quality of life.

Science helps us understand that pet obesity, a significant concern for canine populations, is primarily caused by factors like insufficient exercise, overfeeding, and underlying health conditions. Health-and-wellness routines, such as fitness-and-exercise plans and weight-management strategies, play a crucial role in managing dogs' weight and preventing obesity.
Dog owners who prioritize their dogs' health through regular exercise, a balanced diet, and routine veterinary checkups can significantly reduce the risks associated with obesity, including diabetes, heart disease, and a decreased lifespan. Collaboration with veterinarians and adherence to tailored weight management plans are essential for ensuring dog obesity does not become an unmanageable issue in pet-focused communities.
