Okay, back to the dog food ratings - Here's a chart showing grades for some of the popular foods. I'm a hobby breeder - and all my dogs are fed Nutro Natural Choice - which the pups are weaned to when they're old enough. I have fed a combination raw food, home cooked and kibble diet in the past, but now mostly just do the kibble, as it's just too time-consuming with 9 dogs to do anything else. There <span style="color: #FF0000">are</span> better rated foods out there - but I live in a small rural town - and the Nutro is the best food available to me <span style="text-decoration: underline">locally</span> and all my dogs love it. Science Diet is NOT rated well - (gets an F), but many vets recommend it because: 1) <span style="color: #CC0000">they really don't know much about canine nutrition</span>; and 2) they <span style="color: #CC0000">sell</span> it so naturally they recommend it.
If I had a better supplier for raw foods, I'd probably just do a BARF diet, but at the prices charged here I can't afford it. Most dogs do very well on a Bones & Appropriate Raw Foods diet. Mine still get chicken backs, necks, wings for treats occasionally. I NEVER feed canned foods. Kibble is much better for their teeth.
I hope this information is useful.
