I did switch, i was giving him Royal Canine, now i just bought life's abundance which is an all natural no preservative dog food, i started introducing it today, but he has not done anything outside since his las poop and pee sometime in the early morning hour. I was up at 6:40 and put him in his crate and since then have been outside every hour and nothing yet. I can see a crate accident coming on soon. He just stopped going outside he prefers the crate. Yesterday my husband took him out at night he had already pooped in the crate and then pooped again outside, he got treated and praised for going outside, now today back to nothing.
