Is grain-free healthy for my puppy? When can I switch to adult food?

Hey guys, I’m slowly transitioning my dogs over to adult food but they are still getting their puppy food. Mia always has some kind of allergy so I was looking into getting BLUE Basics® Grain-Free Salmon & Potato Recipe For Adult Dogs but it doesn’t have any chicken or poultry by-product meals, corn, wheat, soy, dairy or eggs. Is that even healthy missing all of those food groups? Right now my dogs are on Blue buffalo freedom grain free.

I see Mia is seven months old. She is too young to be on an adult food, she won't be old enough for that until she is 12 month of age. I would hold off on the transition until then. As for that Blue Buffalo food, it's honestly a terrible brand and you'd be hard pressed to find a vet who recommends it. You also need to know vets are seeing an increase in dogs developing dilated cardiomyopathy (DCM) who are on grain free foods. The FDA is investigating that link, and Blue Buffalo is named as one of the foods. I never recommend feeding grain free, it's a dangerous fad. Grain allergies are actually very rare in dogs. If you think Mia has an allergy, have her seen by a vet to diagnose what is it so she can be treated properly and I would seriously consider getting your dogs off the grain free food.
