I don’t think that requiring leashes is the way to go. Too many people tie dogs up in a manner to where they are still a safety issue for others. Or, simply let them loose when no one seems looking. It’s time to not allow dogs on show grounds at all.
There’s no reasonable way for show management to track the credentials/history of dogs that are brought onto show premises. Neither would it work to ban breeds–this would be impossible to prove/enforce. The only reasonable solution is to not allow dogs. A person who needs to travel with their dog could still bring their dog, but would have to leave them at the hotel or campground where they were staying. Alternatively, shows could offer a doggie daycare service. Dogs should be prohibited from the remainder of the show grounds/barn areas. The proceeds of stiff fines could be donated to a local animal shelter. It’s weird how people seem to be able to enjoy many other types of sports and activities without involving dogs, I’m sure equestrians would be able to acclimatize.
I have been showing for over four decades and I’m scratching my head here but I have never had a bad incident involving children, at least not one I can remember. My horses are well acclimatized to both children and dogs, so children running around minding their own business does not bother them, so maybe I am less sensitive than others. I am also a dog lover and own quite a few dogs, but lately there seem to be negative dog incidents at just about every show I go to, whether it is to myself or someone else. I consider a negative dog incident to be: horse being chased/nipped or harassed by a loose dog, dog tied in dangerous manner (whereby it can still harass horses or risk entangling a horse), loose dog spooking a horse, or dog excessively barking or crying while crated or penned in stabling area.
I’m well aware that a lot of people dislike children, nonetheless, since as a sport we are trying to attract and retain spectators and participants, it would be foolish to discourage people from coming to spectate as families and equally bizarre and foolish to discourage the next generation of equestrian sportsmen and women. Maybe kids are attacking, chasing, harassing or otherwise endangering other people’s horses, but I’ve just never seen or experienced that. I think it is quite small minded and petty to talk about banning children.
