Hi guys,
I have had my golden retriever puppy for 2 weeks now, and after reading all the comments in this forum, i decided to feed him with Wellness puppy food. I just realized I have been feeding him with the normal puppy food and not the large breed one. And also, he lost almost a pound in last week. From 16lbs to 15.2lbs. He is 10 weeks old. I am going to buy him the wellness for large breed puppy today. Do you know if the reason was the type of puppy food? Do you recommend any other type of Food?
After spending hours of reading the forums, here is my list but I can’t decide which one:
1. Wellness Dry Large Breed Puppy Food (~$62/30lbs)
2. Purina Pro Plan FOCUS Puppy Lamb and Rice (~$44/$34lbs)
3. Nutri Source Large Breed Puppy (~$55/30lbs)
4. Holistic Complete Large/Giant Breed ($45/15lbs)
5. FROMM Large Breed Puppy (~$60/30lbs)
6. Orijen Large Breed Puppy ($89/25lbs)

I would eliminate #6 just because it’s expensive. Any comment on the rest? Or any additional option I need to consider? Are these all AAFCO approved!?

Thanks
