I don't see much difference other than possibly more coat in the 2nd picture and a very happy looking dog. Personally, I don't know if you can really judge the cosmetic benefits of a food after just one bag - it's probably too short of a time period for the body to adjust. Without hesitation I would say that between those two foods, Acana is a much higher quality food.
I want to tell you that your Bruno has grown in the a very handsome looking fella. I remember you were so concerned a while back that he wasn't a good size, etc.
the difference:
1. we feed less with acana
2. look at the front leg muscle on second pict, being not exercise it's noticeable that his muscle grown so much well than the first picture
3. yes, the coat difference
i'm very surprise what a food can do just with one bag consumption.
At first pict, we finished bag twice as much as second pict.
acana is the food that i think he like better than the other, but i really have a seriously inconsistency of stool with this food. some day better stool, some other day he had a soft and sticky stool.My suggestion would be to quit experimenting and let the dog grow up, feed him the food that he likes and that you think he is healthiest on.. With all due respect, this shouldn't be a project.
He's going to be what his genetics made him.
