I was just about to buy my dog another 40 lb bag of IAMS. I should introduce my dog first My dogs name is Isaac and he's a seven year old black lab.He grew up eating eukanuba as I thought it was the best food out there( or so my former vet told me) I've been feeding him Iams as I thought it was the next best and money has been tight latley. I love my dog very much and want the best for him. He's very healthy and his coat is beautiful. I did a google search on Iams vs Eukanuba as I wanted to see if I could justify the added expense,thats when I came across some very pointed negative comments about the Iams company originating from this forum, That thier food is sub standard and that they practice animal cruelty. Well I like to think of myself as an aware and conscientous consumer, and if all this is true I guess I'm not that aware or conscientous at all. Please enlighten me and give me some tips as to a good quality large breed food for aging dogs ( my dog has some aches joint trouble I think) He needs food now but I'll be waiting to hear back fom you guys before I go and buy food so I hope someone is paying
