i feed my corgi eukanuba sensitive skin because she was always licking and biting her paws and the vet said it would also keep her coat shiny and reduce shedding. she's been on it for over a year and nothing really has changed. i'd like to put her on a food that is maybe healthier and help her lose some weight- she's a bit chubby :) ... has anyone else had this problem or could give me some advice?
