I learned about the dogfood advisor site early on and as an ex breeder licensed trainer I believed I was feeding my dog the best possible food. Nutrisca Lamb is a #5 on that list and lamb is more digestible than other types of food for dogs I had always learned.
A rescue German Shepherd at 5 months she came along really well until age 4 when her skin became dry and full of scabs. I sent away to a site that analized dogs for allergies and found out that almost everything in that dog food she was allergic to.
I switched to the Nutrisca chicken food right away and I can see a huge difference in only a month. Here is the site for $80 you will know, I so believe in doing this!
