Losing Weight Improves Quality of Life
Pounds shed relates to less pain, more energy

Being overweight affects our dogs’ health and longevity, and a recent study has examined the effect it has on quality of life. In a study in Great Britain, where it is estimated that a third of all dogs are obese, researchers investigated the change in quality of life of dogs who have lost weight.

They found that dogs who lose weight had a corresponding increase in their quality of life. They showed greater vitality and experienced less pain. The more weight they lost, the greater the improvement was in these measures of quality of life. Interestingly, those dogs who did not lose weight over the course of the study had lower quality of life scores at the start of the study compared with those dogs who were able to shed some excess pounds.

If you have a dog who has successfully lost weight, what changes did you notice in your dog’s quality of life?
