Hi, we just adopted our first Bulldog Jake! He is 9yrs old. I have a question on what type of harness and or collar you use for your doggies? He came to us with a harness, however he can back right out of it He is a big love bug all 70lbs of him. Second question is does anyone feed their dog wet food? He will not touch dry and the rescue gave us Beneful chopped, which I would like to change. Thanks!
