Hi Jessica-
Depending on the breed, a puppy will reach an adult at different ages. Small and medium sized dogs when fully grown can transition to adult food at 1 year, toy breeds can often switch earlier at 9 months, large dogs over 50lbs at mature weight is about 18 months and for giant breeds some say to keep them on a puppy formula until 24 months.
If he was already lean and fit before switching to raw and has now lost more weight, you may be under feeding him. I am all for a lean, conditioned dog, but you can go overboard. Any idea what Leo’s projected adult weight will be with that combo of breeds?
