Okay, this is going to sound kinda weird probably, but About 7 months ago we switched the dogs from PMI High Pro (Basically Purina) to Canidae ALS. Now, I have seen NO CHANGES! The only thing that has changed some is that Lizzie's stool is not runny, but not firm still. No coat or teeth or breath changes. Also, Major's coat seems to be getting worse and worse...any recommendations for that? Is this maybe just because this food is not working? I am going to be changing over to a grain free food in the weeks to come.
