Id definately do that switch. My sister has a half-mastiff, half-american bull dog mix named Holmes and she switched him off Purina and onto Kirkland and he hasn't been eating quite as much, he also lost this itch that he had going because of the Purina apparently being not so healthy for dogs.:angry7: Most dogs normally fill in fully at the end of the 2 year mark and are fully done growing. On the note of the gravy thing DRENO, its kinda a spoiled thing. Holmes did it when we put beef/chicken broth over his food, the next day, he would look at you like "wtf is this garbage? Im not eating this". Its really just them being spoiled and wanting to get that yummy human stuff on/in their food. Might wanna break him of that soon or it turns into an every night thing. I only do it for Holmes now maybe once a month if that even and he doesnt do that "I wont eat this" next day thing cuz he knows thats all he is gonna get:toothy10:
