We feed our puppies Royal Canin Large Puppy
Switching your dog’s food abruptly can cause gastrointestinal upset such as vomiting, diarrhea, and a decreased appetite. Any time you decide to change your dog’s food, you should transition to the new diet gradually in order to give your dog’s system time to adjust to the change. Ideally, these transitions should happen over 5-7 days. During this transition, you will gradually incorporate more and more of the new food by mixing it with your dog’s current diet. For most dogs, a good diet transition will look like this:
Day 1: 25% new diet and 75% old diet.
Day 3: 50% new diet and 50% old diet.
Day 5: 75% new diet and 25% old diet.
Day 7: 100% new diet.
