Hi Tina...
Well, if you are " free feeding ", leaving food down all the time, I would be Very Careful about that. You now, truly have a Pack of dogs. I could NEVER do that here, ever. It would be a Guaranteed Fight...
I can't even give the dog's Real Bones from the Butcher, great for their teeth, but again, a Real bone would be treated as food, by them, a Guaranteed Fight....
Certain dog's eat in certain rooms here. When done, all bowls come up....finished or not...
