How long are you supposed to give your dog puppy food? But once your pup is six to 12 months old those needs change. That’s usually when your puppy is nearing his adult height and can transition to adult food. Spaying or neutering usually occurs at this age as well, lowering your dog’s need for increased energy; hence a reason to switch from puppy to adult dog food.
Can a 1 year old dog eat puppy food? You should feed puppy food until your puppy reaches maturity. Once he has reached maturity, you can switch to adult dog food. Not all breeds reach maturity at the same age, however, so this can make it harder to know when to switch.
Can a 2 year old dog eat puppy food? Short answer – yes, but they probably shouldn’t. Puppy foods are specifically designed to accommodate growth. Once your dog has reached adulthood, the only way a puppy food will help them grow is out.
What happens if a puppy eats adult dog food? While puppy food is good for puppies, you shouldn’t keep feeding it to your dog once he’s fully grown, since puppy foods have a lot of calories and fat. If you do, he could become overweight because his body isn’t using up as many nutrients as a young, hyper puppy.
