I just adopted a 3 1/2 mos. Shepherd/Rotty Mix and my boyfriend and I just purchased some Nutro Ultra Mix. I have been reading the threads about this brand and now i am a bit concerned but I am not sure of my options. He was a stray and is pretty emaciated so I want to give him something with lots of nutrition to get him healthy again. The only dog food stores in my Area are Petsmart and a Feeders Supply. I am not sure of my options. Can anyone give me some information?
