Preferably from Amazon if possible
I’ve bought bully boxes, kongs, antlers, rubber treat balls. He loses interest with the antlers etc if he figures out he can’t rip them apart, the rubber treat ball was a winner but at £12 didn’t last more than a couple of days.
I’ve bought those Hide shaped rings and bones but he mullers them to mush and then throws up a white foam mush. They are off the list!
