Which Canned Food?

Feeding an all canned diet is going to get very price, very fast with a large breed dog. Have you considered just using the canned as a topper, and mixing it in with the kibble to encourage them to eat? How about putting a little chicken broth on it? There is, of course, always the "tough love" method.

Personally, I am not a huge fan of dogfoodanalysis and would not give any money to Innova after the Procter & Gamble buyout.

I'd personally give Chicken Soup For the Soul canned food a try, if you must do the whole canned thing. Probably the best for the money.

Procter & Gamble, the company that makes Iams and Eukanuba, purchased Nautra pet foods (who are the people who make Innova/California Naturals/Evo). I personally do not care much for this company at all, and expect to see drastic quality reduction in the future. As of right now there is nothing wrong with the food... I just don't trust that to say so for much longer.

Wellness is a great brand. If you're really willing to pay that price, then go for it.
