Ok, here's the list of foods I have tried and the results with *my* dogs.
I started out feeding Nutro (many many years ago), but too much scratching.
Switched to Nature's Variety
rairie. I LOVE this food, but it is getting more difficult to find a source for it up here for the one dog that I can't feed chicken based foods to, and of course she does not like any foods I've tried with lamb in it.
Nature's Variety: Instinct - grain free, good food, but can't afford to feed all my dogs on it.
Fromm: dogs got dull coats, and I ended up feeding almost double to what I normally fed.
Canidae: dogs did ok, but more poop, fed a bit more than the Prairie, had a few odd things on it, and I finally quit feeding it with my last litter of pups because it gave them extreme diarrhea, and one of the pups actually would NOT eat it and started losing weight...had another dog after the pups were born come in and did not do well on it either (every week it would have a bout of diarrhea & vomiting), so the food is no longer in my house.
Merrick's: dogs did ok on the varieties I fed (I only picked it up when I was in the US and could bring it back with me)
Currently, I have one dog on Orijen (the one that can't eat chicken)
And the rest of the crew is on one of the Acana grain free. Yes, a bit pricer, BUT I feed far less than I was feeding and they are doing really well on it. Nice shiny coats, less poop.....so far so good.
When you look at the labels on the food, you want to see a meat as #1 (preferably 2-3 meats in the top 5 ingredients).
What I would watch out for and try to avoid: corn, wheat and keep an eye out further down in the ingredient list for beet pulp...that is an ingredient that can cause a lot of allergy problems (more so in the smaller breeds, but our Saint couldn't handle anything with beet pulp in it).
I don't know what you have access to, so can't steer you towards, or away from any certain brands. And keep in mind that not every dog will do as well as others on certain foods. Also, with the grain frees or anything with more meat in it, it will cost more, but you should not be feeding as much.....
I also would NOT recommend feeding most puppy foods.....
If you have any questions about certain brands or reading the labels, feel free to email me and I can try to help you out more....
