I feed only canned, rehydrated, or fresh/frozen type foods. I rotate my dog’s food every 3 to 5 meals, feeding twice a day. Rarely he will try a food and get indigestion, but because he is used to variety he does OK with most foods and proteins. Like humans, dogs can get used to a varied diet and have fewer digestion problems.
Rotation keeps diets interesting, covers more nutritional bases, and you can buy foods that are on sale. Plus, I think it is just plain fun to pick out a “menu” for my dog.
BTW, I started my dog’s rotation diet about 8 months after I adopted him. When I adopted him he was 5 years old. Because he was an unclaimed stray, his past history is uncertain. The rescue was feeding him a popular low-end kibble dog food that they receive regularly due to a grant from the company.
