When I got Parker from the SPCA back in 2001 he was an awful mess, he'd been there for months and done the round of SPCA loan-outs but never adopted, probably because he had fairly regular diahrea and his coat looked awful. A friend mentioned Nutro Lamb & Rice (dry) which I bought and haven't looked back since. The change was astounding, the diahrrea disappeared almost immediately and his coat improved dramatically over the following couple of weeks. I'm an ardent label reader on everything and I checked labels for all the different brands, Purina, Science Diet, Iams etc. and Nutro was the only one as I recall that had lamb as the first ingredient listed and rice as the second, all the others had those ingredients listed further down and usually accompanied by some other grain like wheat. My sister, a vets assistant, was over one day telling me I should switch him to some expensive brand I'd never heard of, they sell, extolling it's virtues, gave me a sample bag which I never gave Parker. I cut the two labels off both bags and gave them her to look at and said which would you feed your dog now.. The highly priced brand they were flogging was again a big mix of grain and corn meal.
