Canine Obesity: A Modern Epidemic


The rise in canine obesity mirrors a similar trend observed in humans, with a significant proportion of the dog population falling into the overweight or obese category. Recent studies indicate that 30–40% of dogs are now overweight or obese, a situation described by some experts as reaching pandemic proportions​​. 

Statistical Evidence of the Trend of Canine Obesity

The 2022 Pet Obesity Prevalence Survey revealed that 59% of dogs were classified as overweight or obese, marking an increase from 56% in 2017 and 2018​​. Banfield Pet Hospital’s 2020 Veterinary Emerging Topics (VET) Report further highlighted this problem, stating that more than half of all adult dogs seen at Banfield’s hospitals in 2019 were overweight, marking pet obesity as an epidemic​​.

Health Implications of Canine Obesity

Canine obesity is not merely an aesthetic issue but a significant health threat that has been growing in prevalence. The ramifications of obesity in dogs are manifold and often serious, impacting their quality and span of life adversely. Here are some of the health implications associated with canine obesity:

  • Osteoarthritis and Lameness – Obesity puts extra weight on a dog’s joints, leading to osteoarthritis, a painful condition. 
  • Reduced Life Expectancy – Obesity has been found to adversely impact the longevity of dogs. 
  • Cardio-respiratory Problems – Obese dogs are at risk of developing cardio and respiratory problems due to the extra body fat especially during dog pregnancy times.
  • Diabetes – Much like humans, obesity in dogs can lead to diabetes. 
  • Increased Risk of Tumours and Cancers: Obesity may increase the risk of certain tumours such as benign fatty tumours (lipomas), as well as breast and bladder cancer (transitional cell carcinoma)​.
  • Skin Diseases – Overweight dogs tend to have extra skin folds which can cause irritation and infection by bacteria, leading to various skin diseases​. 
  • Reduced Immunity – The reduction in immunity in obese dogs puts them at a higher risk of infections and other illnesses.

A Dog Owner’s Role in Combating Obesity

To curb this growing epidemic, dog owners are encouraged to take active measures in maintaining a healthy weight for their pets. Tips for achieving and maintaining a healthy weight in dogs include:

  1. Consulting with a vet to devise a tailored diet and exercise regimen; it’s advisable to gradually increase the exercise, like taking longer walks​​.
  2. Establishing a fixed amount of food each day, using a measuring scoop to help control portion sizes and prevent overfeeding​​.
  3. Opting for high-quality dog food and examining the label to understand the caloric content and serving sizes​​.
  4. Ensuring at least 30 minutes of physical activity for dogs daily, as recommended by experts​​.

Veterinary Intervention in Obesity Management

Veterinarians play a pivotal role in combating canine obesity. They are tasked with diagnosing and discussing obesity with pet owners, and are encouraged to adhere to recommendations for preventing and addressing overweight and obesity in companion animals​​. 

Recent research has led to better characterization of obesity in dogs and the identification of new therapeutic approaches, aiding veterinarians in providing more effective treatments​​. Tools and resources, such as the Pet Obesity Toolkit created by Cornell alumni, have been developed to assist veterinarians in addressing pet obesity.

Effective communication and education on the part of veterinarians, especially about the nutritional needs of dogs and preventive care, are essential for tackling the obesity epidemic head-on​​.


The escalating prevalence of canine obesity underscores a modern-day epidemic that demands urgent attention from both pet owners and the veterinary community. The health implications associated with obesity in dogs are severe and often life-altering, impacting their overall wellbeing, quality of life, and longevity. The adverse effects paint a grim picture of the life of an obese dog.

However, the silver lining in this scenario is that canine obesity is preventable and manageable. With the correct interventions, education, and a commitment to a healthier lifestyle for our pets, the tide of this epidemic can be turned. Veterinarians are at the forefront of this battle, armed with the knowledge, tools, and resources to guide pet owners in the right direction. Their role in diagnosing, educating, and formulating weight management plans is pivotal for tackling this issue head-on.

Dog owners too have a significant role to play. Being the primary caregivers, their actions and decisions directly impact the health of their pets. Implementing a balanced diet, ensuring regular exercise, and adhering to veterinary advice are crucial steps every dog owner can take to prevent or combat obesity in their furry companions. Moreover, recognizing the signs of obesity early on can pave the way for timely interventions, preventing the onset of associated health problems.
