Hello, Need to get Bentley healthy. What food brand do you use? We’ve used Victor grain free, I meal prepped his food (white fish with veggies), royal canine & honest kitchen. I can’t seem to get his coat healthy and nice.Not sure if he’s allergic to something in our grass Or food. I wanted the vet to be our last resort to avoid any type of steroids, but I noticed his coat is getting worst.
