IS it ok to feed my 6 week old boxer Eukanuba large breed puppy food???

My german shepherd puppy is 10 weeks old and I have been feeding him regular puppy food. My breeder said I should wait a certain amount of time before I feed him large breed puppy food because of something that has to do with how fast it makes them grow & it’s now good for them???
Has anyone heard of this or do you know if I should start feeding him large breed puppy food yet? Thank You

I have a 5 month old pit bull puppy (bully breed) and I feed him Iams puppy food what will be better for his build and I also have a Dacshund thats 4 years old 10 pounds and they eat together? I want to find the best food for both of them and have been told Canidae. Any better foods that you would suggest?

I have a14 week old shiba inu puppy, duke. I currently feed him Artemis: Small Breed Puppy Formula. I know this is really good food however i want to give him a healthier diet. How would i go about doing this, raw diet? what is raw diet exactly? Also could i do like cooked chicken, or steak pieces along with mashed fruits and veggie?

Links to websites or recipes for some good homemade food to go along with his dry food would be greatly appreciated.

I have a new puppy that is saint bernard/great dane mix and vet said he should be on a large breed puppy food? I was just looking for any suggestions on a large breed puppy food that is all natural?
