A small study found that about half of all dogs eventually regain weight after a period of weight loss, but that long-term use of a weight management diet can limit regain in the follow-up period.

In an article appearing online May 12 in the Veterinary Journal, researchers at the University of Liverpool in England reported on a study of 33 obese dogs that lost weight and were then put on a maintenance regimen. Median duration of follow-up was 640 days.

Fourteen dogs maintained their weight during the follow-up period, three dogs lost more than 5 percent in additional weight, and 16 dogs gained more than 5 percent in weight. Dogs on a weight loss diet regained less weight than did dogs on a standard maintenance diet.
