Thanks for your reply.  My breeder is in Brazil, so trying to feed what he was feeding was impossible. :-) What I did was try to get a food that was as similar to the one my breeder was using.  He uses a formula with chondroitin & glucosamine.  I already feed Victor Dog Food to my dogs (they are rated as 4 stars), so I saw one that had those ingredients in the formula already.

It's good to know that the 3% difference in protein wouldn't deprive my puppy of nutrients he needs & he will still grow to whatever his genes tell him to. :-)  I was concerned about that.  He's getting so tall & lanky these days. LOL!  He's taller than my German Pinscher who is about 18.5" at the shoulders, Bruno is now closer to 20" at the shoulders (5 months old). 

I used to feed raw when I was competing in AKC conformation back in the day when my German Pinscher was in his hey-days. I do plan on going back to raw feeding in the near future.  Right now, I just don't have room for it in my life (figuratively & literally) right now. 

Thanks again for your reply! :-)
