I used to feed my dog wellness but now I even found a better food. Its called Timberwolf Organics. Its very high in protein (well they do have a lower protein type as well)...the protein level varies. I believe one of the flavors from Timberwolf has 34% protein. This is excellent if you've got an underweight dog or a dog that exercises ALOT...
The food is very expensive though and hard to find in Canada. One store in Oakville, ON sells it and that's the only one in like..the province lol.
I think it cost me 50 bux for a medium sized bag. My dogs love it though, including my kibble wary Chihuahua. Plus, you don't have to feed alot since its very high in quality...for example with a **** brand like Iams, you'd have to feed about 3 cups to a 55lb dog? With this, my 55lb pittie gets 3/4 of a cup and I"ll throw in a tablespoon of yoghurt...its great if anyone wants to take a look at it.
They also carry a line of food for cats as well
