Nutritionally sound vegan diets for dogs may be healthier and less hazardous than conventional or raw meat-based diets, according to a study by the UK's University of Winchester.

What to know:

  • Overall, dogs being fed conventional diets were less healthy than dogs on raw meat or vegan diets.

  • In a yearlong study, nearly half of the dogs fed conventional meat-based diets required nonroutine medication compared with only a third of the dogs who were fed vegan diets.

  • Dogs on raw meat diets appeared to be healthier than those on vegan diets, but prior research has linked raw meat diets to increased risk of pathogens and nutritional deficiencies.

  • The most common health problem with dogs is associated with obesity and is related to a meat-based diet.

  • Dog guardians choosing unconventional diets for their pets usually do so because of concerns regarding the environment, the treatment of animals used as food, and the health of their pets.
