People are just concerned about the wheel, it needs to go. Numerous chins have broken legs and paws, been given concussions and brain damage from that type of wheel, I personally know of 3 broken legs and the brain damage 1st hand from the rescue group I work with and many more on the forums over the years. Why on earth would you get defensive about something that could harm your chins is beyond me and your breeder should know better, so shame on them.
