Learning how to change dog foods slowly is important to keep your pup happy. Abrupt diet changes can cause vomiting, excess gas, constipation or diarrhea.
In order to avoid these symptoms, most experts recommend transitioning to a new food gradually. Start by mixing in small amounts of the new food (about 25 percent.) Over a period of 1-2 weeks, increase the proportion of new food every few days to 50 percent, then 75 percent, and ultimately 100 percent.
Pet owners should know that the appearance of their dogs’ stool may change due to different amounts of fiber and protein in the new diet. If at any point, however, your dog develops symptoms such as a loss of appetite, vomiting, loose stools or other gastrointestinal problems, consult your veterinarian.
