DEAR DR. FOX: I’ve been feeding Orijen grain-free large puppy food to my golden retriever. She will be 1 year old this month, and I will soon need to switch her to an adult food. I’ve been seeing a lot of conversations regarding grain-free pet food; is there an advantage to this?

This subject is very confusing, and I want to do the right thing for my almost-adult-puppy. — D.M., Trenton, New Jersey
