When should my puppy start eating adult food?

When should my puppy start eating adult food?

Our question this week:

When should my puppy start eating adult food?

Great question! Growing puppies should only be fed a high quality growth-type diet which you continue feeding this diet until your dog reaches 80 to 90 percent of his anticipated adult weight. For most dogs, this occurs around 9 months of age.

Giant breed dogs pose a special problem. These breeds are prone to skeletal problems if not fed properly during their growing phase. There are now special diets for giant breed puppies. For optimal health, feed your giant breed pup this special diet until he is 12 to 18 months of age.

Once your puppy has reached the age for a diet change, gradually begin changing his diet by feeding ¼ adult food and ¾ puppy food for a few days. Then add ½ adult food and ½ puppy food. After a few more days, feed ¾ adult food and ¼ puppy food. Then, you can feed straight adult food.



Our question this week came from Helen B. in Columbus, Ohio.
