As dog owners, we love our pets and want to give them the best lives possible. Dogs are loyal companions who provide us with unconditional love and joy. However, one of the biggest threats to their health and happiness is something that many pet owners overlook: obesity. Obesity is a nutritional disease defined by an excess of body fat, and it is alarmingly common among dogs. According to veterinary studies, a dog is considered overweight when its weight is more than 15% above its ideal weight, and obese when its weight exceeds 30% of its ideal weight (Mason, 1970; Gossellin et al., 2007). The consequences of obesity are not merely cosmetic; they have profound implications for a dog's overall health and quality of life.
The Impact of Obesity on Dogs
One of the most serious conditions linked to obesity in dogs is osteoarthritis, also known as degenerative joint disease (DJD). Osteoarthritis is characterised by the progressive and permanent deterioration of the articular cartilage and surrounding joint tissues. The combination of obesity and osteoarthritis is so prevalent that it has been given a specific name: arthrobesity©. This term describes the situation where a dog is affected by both excessive adipose tissue and osteoarthritis in at least one synovial joint (Chandler, 2016). Arthrobesity© is a colossal cause of misery to millions of dogs, causing chronic pain and severely limiting their mobility.
Why Arthrobesity Matters
Arthrobesity© is not just a matter of extra weight putting more strain on a dog's joints. It also involves complex biological processes that contribute to the progression of osteoarthritis. Overweight and obese dogs are living with constant low-grade inflammation, which enhances the phenotypic expression of osteoarthritis compared to genetically similar dogs that remain lean (Fox, 2014). This means that obese dogs are more likely to develop severe joint pain and immobility, even if they share the same genetic predisposition to osteoarthritis as their leaner counterparts. The constant inflammation acts as a greater driver of osteoarthritis progression than the mere mechanical impact of carrying extra weight.
The Importance of Prevention and Treatment
The good news is that we have the power to help our dogs avoid the misery of obesity and arthrobesity©. Prevention starts with proper diet and exercise. Feeding your dog a balanced diet appropriate for their age, size, and activity level is crucial. Avoid giving them too many treats and ensure they get regular physical activity. Even simple changes like more frequent walks or playtime can make a significant difference in maintaining a healthy weight.
For dogs that are already overweight or obese, it’s essential to seek veterinary advice. A vet can help develop a weight loss plan that may include a calorie-controlled diet, increased exercise, and possibly medication to manage pain or other health issues related to obesity. Regular check-ups can also help monitor the dog’s progress and adjust the plan as needed.
Conclusion
Dogs bring joy and love into our lives, and they deserve the best care we can provide. Obesity is a significant health issue that not only reduces a dog's quality of life but also contributes to the painful condition of osteoarthritis. By recognising the risks of obesity and taking proactive steps to maintain a healthy weight, we can help our dogs live longer, healthier, and happier lives
