into an adult food.? I know the most popular one is pedigree. But is there any other cheaper but good quality dog food. Perhaps 'Alpo'. What about treats? Can I use the dog food as well? Or can I use treats with no brand?

What age is apropriate for the exchange? Should I buy a whole big pack of dog food or smaller packs?

Please answer.

im sorry, but pedigree IS CHEAP. Alpo!!! omg. thats like letting your dog serf through a dumpster. please lesson yourself in ingredients in dog foods. if your not willing to spend the money on the food, then dont have the dog. most dogs can change over to an adult food at 8months to a year. but dogs that are large and giant breeds, ESPECIALLY THE GIANTS should never be on puppy food to begin with.
