I would not recommend that you use Puppy Chow, but rather see him eat something like Eukanuba for Puppies, or Science Diet Puppy. The Purina Puppy Chow is sprayed with animal fat and a lot of the calories in the product are a result of that fat. There are other good foods out there such as Wellness, Back to Basics, Neutro, Canadia, etc. that will be much better in the long run. I have raised my last litter of Mini Dachshunds on Canadia and just soak it in warm water till they started to get teeth. My last pup has been crunching it dry since she was 8 weeks old.
I equate dog food quality to "would you want to eat 2 pounds of chuck steak or a 1/2 pound sirloin fillet? They both have the same calories and both will leave you filled, but one will taste better and the slight extra cost will be worth the difference.
I would write more, but it is 11:17 and I have to make it to the CT TBN Meeting for noon..... /forums/images/graemlins/grin.gif
