Hurray! I adopted a dog today and will get to pick it up from the shelter in 5 days. She is 5 months old, so I will need to get her puppy food. My question is: does anyone have a reason why it would be a bad idea to use Kirkland puppy food (dry). I have looked at the ingredients and they look better than Iams, purina ect. It does not have any by-products and the first ingredient is meat. To me, it looks better than Iams or purina ect. I would appreciate any opinions.
Thank you!
