Puppies don't need a raw diet
Like I stated at least 5 times.. Puppies need a balanced puppy food. That's IT
When they are older, than consider the holistic, organic or raw diets.
If you decide to go with a raw diet, consult with a nutritionist that specializes in dog diets. Raw diets are very incomplete if you don't. Dogs get all their vitamins that they need from eating the intestines of other animals. Feeding them just raw meat and carrots isn't going to provide that.
Keep them on puppy food. They don't need raw diets or ultra holisitic/organic diets. They need to grow. That's it. And that's what a balanced, commercial puppy food is going to provide.
The vet I work for does not recommend raw diets due to the dogs getting the same diseases that we get, such as E-coli. If you don't do it right, your dog can get VERY sick.
Switching diets from kibbled food to raw meat is going to give you gastric upset. Stop doing it. Stop trying to switch your dogs food every couple of days. Let them GROW.
