Well just because a breeder recommended it doesn't mean its a good food, most vets recommend UnScience Diet, Pukarina, and Yukanuba.
Just a few reasons why Nutro isn't a great food (not putting you down for it there are still alot worse food)
(the following is a direct quote form
www.dogfoodanalysis.com )
Pros: First ingredient is a named meat product.
Cons: Insufficient meat products, fat of unidentifiable origin, use of controversial fillers.
"The first ingredient in the food is a named meat ingredient.
The primary grain in this food is rice. Rice is a decent quality grain; however there are three rice products in the top four ingredients of this food. If they were not “split” (see main page for note about splitting), then it is likely that rice would be the primary ingredient in the food.
Poultry fat is an ingredient of unidentified origin for which it is impossible to determine source or quality. Unidentified ingredients are usually very low quality. AAFCO define this as obtained from the tissues of poultry in the commercial processes of rendering or extracting. It consists predominantly of glyceride esters of fatty acids and contains no additions of free fatty acids. If an antioxidant is used, the common name or names must be indicated, followed by the words "used as a preservative".
Rice gluten is a grain fragment (filler) likely to be similar to corn gluten. The AAFCO definition of corn gluten is “the dried residue from corn after the removal of the larger part of the starch and germ, and the separation of the bran by the process employed in the wet milling manufacture of corn starch or syrup, or by enzymatic treatment of the endosperm.” In plain English, that which remains after all the nutritious bits have been removed.
Beet pulp is another controversial ingredient – it is a by-product, being dried residue from sugar beets which has been cleaned and extracted in the process of manufacturing sugar. It is a controversial ingredient in dog food, claimed by some manufacturers to be a good source of fibre, and derided by others as an ingredient added to slow down the transition of rancid animal fats and causing stress to kidney and liver in the process. We note that beet pulp is an ingredient that commonly causes problems for dogs, including allergies and ear infections, and prefer not to see it used in dog food. There are less controversial products around if additional fibre is required.
We would prefer to see the use of whole eggs than egg product. "
If your going to spend the money on a food like Nutro I suggest you look into Canidae aswell its hands down a 10 times better food and priced the same.
