Jesus.. Seriously Casablanca I dont know you and you dont know me but if anyone goes through all the trouble and time of showing a dog I think that shows a hell of alot of care, The dog needs to be in good conditions for shows surely you can understand that?
Another thing I find it disapointing that you need to bring up someones age. Your meant to be older and more sensible ACT LIKE IT! jesus!
Enough said.
I'm sorry to hear about your Riot, Maybe talking to the parents of the kids and explaining that its very serious and that it does affect your dog in a bad way even showing them might show how serious it is. I bet the kids dont understand about it, Are they young or old enough to know better?
