I had the "pleasure" of visiting the premises of a breeder of Yorkshire Terriers just a week before a Crufts show that they were entered in. I saw what must be a dozen or so dogs, in cages with their fur tied up into certain positions, all barking in what seemed like a stressful manner. I could only assume that they had been there a while already and that they would spend considerable time in those small cages in the run-up to Crufts. The lengths that humans go to in order to show how good they are at manipulating the looks of a dog is beyond me. I fully understand that some dogs are bred for specific purposes, but I imagine only a small amount were, in the past, bred the way they are for their looks. I'm all for breeding for purpose where the purpose is something that the dogs enjoy and is inherently useful to humans, but not this. Maybe gun-dogs in Crufts should compete in a way that shows how good they are at retrieving, and terriers for their ability to catch rats in barns.
I've been involved in the poultry show scene and bred birds to show, but found that there were too many people prepared to go to lengths that i wasn't prepared to go to in order to succeed. I wasn't happy with being associated with that and stopped showing last year. As awful as this poisoning is, it doesn't surprise me. A lot of the show scenes seem to be full of the vilest human beings I've met.
