Instructions
Choose a dog food with meat as the first ingredient. It's important to ensure that the food is comprised mainly of meat.
Try different kinds of foods. If you suspect chicken may be the cause for your dog's loose stools, switch to a lamb-based dog food, for example. If you suspect wheat is the culprit, find a dog food without wheat-based filler.
Gradually mix in the new food with the old. Most dog food has a guide on the side or back of the bag advising how much new food to mix in with old food. Typically, start mixing 25% new food with old food for the first three days. Increase this to 50% for days four to six, 75% for days seven to nine, and 100% new food beyond day 10.
