Many dogs with arthritis also carry extra weight. In a study by Marshall et al (link at bottom of post, they looked at a simple but powerful question: Can weight loss alone help dogs with arthritis feel and move better?
The answer was yes.
What the Study Looked At
Researchers studied overweight and obese dogs that had arthritis in their hips or elbows. All of the dogs were pets living at home with their families.
The dogs:
- Were fed fewer calories in a safe, controlled way
- Stayed on the same exercise routine
- Did not receive pain medications during the study
The study lasted around four months, and the dogs were checked often.
How the Dogs Were Measured
The researchers looked at improvement in three main ways:
- How the dogs looked when they walked and trotted
- How much weight the dogs put on each leg using special walking plates
- How much weight and body fat the dogs lost
This helped the researchers see both how the dogs felt and how they moved.
What the Study Found
Even small amounts of weight loss made a difference.
Key findings:
- Dogs showed less limping after losing about 6 percent of their body weight
- Objective walking tests improved after about 9 percent weight loss
- More than 80 percent of dogs improved by the end of the study
Many dogs started moving better before they reached an ideal weight.
Why Weight Loss Helps Arthritis
Extra weight puts more pressure on sore joints. Losing weight:
- Reduces stress on hips and elbows
- Makes movement easier
- Helps dogs walk more evenly
Weight loss may also lower inflammation in the body, which can reduce joint pain.
Why This Study Is Important
This study showed that weight loss alone, without drugs or therapy, can improve arthritis symptoms in dogs.
It also showed that:
- Improvement can happen sooner than many owners expect
- Even modest weight loss matters
- Weight control should be part of arthritis treatment
What This Means for Dog Owners
If your dog has arthritis and is overweight:
- Weight loss may help reduce pain
- Your dog may move better with just a small change
- Diet changes can be as important as medications
Always work with your veterinarian to plan safe weight loss. Slow, steady changes work best.
The Takeaway
Dogs with arthritis do not need to lose a lot of weight to feel better. In this study, losing just 6 to 9 percent of body weight helped dogs walk with less pain and better balance.
Helping a dog reach a healthier weight is one of the most effective and natural ways to improve comfort and quality of life.
