Well.
It is by far the best food I have purchased.
Recently, I read in a scientific article that in some brands of dog food, a substance called BHT was detected, which is responsible for skin diseases and cancers in companion animals. And in some products that people use, it creates cancer in the liver. I will not reveal to anyone the brands that have this substance, and you know the reason I cannot do that.
The CANAGAN website says how to change food for the dog to adapt:
25% new food 75% old food for two days
50% --------''------ 50% ---------''------------''------------------
75% -------''------- 25% -------''--------''---------''--------------
100% new food
The difference I noticed was that my dog has three bowel movements a day without any difficulty and less time for me.
CANAGAN is, for me, the best food I have tried for my dog.

My two pug dogs eat anything you give them (anyone who knows about pugs will understand). Everything except this food! We gave it away!
