Gosh. So much to read... eyes... bleeding! hehe.
I fully understand and recognize that there are Border Collies in dog sports that are wonky, and breeders should not focus wholey on peformance in dog sports as a reason to breed, or as a determining factor in the worthiness of a dog TO breed. Dog sports are
supposed to simply be an outlet for working dogs (and non-working breeds) and a fun, bonding experience for the dogs and owners. Having been on two Flyball teams, both of which were SUPER competitive, and having been to lots of tournaments... I feel I've heard both sides of the story.
The environment of a Flyball tournament is incredibly fast-paced and stimulating, keep that in mind. The dogs in tournies will be barking, spinning, and carrying on when they know they're about to run... but is that how they are 24/7? NO. Sure, some of them are that wound up all the time, but the vast majority are not. Gonzo literally goes apeshit when he's about to run at Flyball tournaments. Does he go apeshit at practice? No, maybe a little, but not anywhere near that extent. And he quietly hangs out in his crate or x-pen for the majority of the time at tournies. At home, he's perfectly laid back and calm. I don't think a Flyball tournament is an appropriate or fair environment to judge the "off-switch" of any BC, or any dog... you cannot get the full story until you've seen that same dog hanging out at home, at the park, or even out working livestock.
Even though Flyball really is an intense sport - how is it detrimental to the breed?!? It takes a LOT of training and a LOT of control for those dogs to not only run the course at the speed that they do, but also to completely ignore dozens of other dogs around them, barking, and the dogs racing past them. If a single dog on a team crosses over, the entire team has to forfeit the heat! The dog has to have drive to work for their owner and has to be well trained, or either the dog will be extremely slow, they won't enjoy/participate in the experience, or they'll be forfeiting heats for the team. There IS a reason that Border Collies dominate in dog sports, particularly Flyball... it requires a hefty amount of work ethic, and desire to please their owners, and athleticism in general. At least Border Collies in Flyball are utilizing SOME of what makes them great working dogs, while Border Collies in a show ring utilize nothing in regards to brains or biddability. In fact, there was a "Barbie Collie" in my classes, and she had absolutely no working/herding/anything drive, bless her. Her owner would tell her to go over the jumps, tell her to trigger the box, and tell her to bring the ball back over. But, anyone could see that the dog didn't enjoy it, she didn't enjoy working, she had no desire for it and she would amble slowly through the course every time. Of course, because she was a show Champion, it didn't matter that she didn't have the drive to fetch a ball without being forced to... last time I saw her, she was about to be bred by another Champion BC. Yippee.
I have met several AWESOME, well-bred working Border Collies who are also amazing Flyball dogs. Gonzo is completely working bred, and he loves Flyball. I have probably met hundreds of BCs at tournaments... some of them were stressed and high strung, but the vast majority were well-adjusted dogs, in general, who were HAPPY and considered Flyball a job. The vast majority of neurotic BCs I have met are not the dogs competing in dog sports, they are the dogs sitting idly in backyards and suffering the neglect of owners who didn't have the time/interest to give them an appropriate "job".
But... as I was saying... ramble, ramble, ramble. haha. I just felt the need to defend Flyball, as although it isn't exactly my cup o' tea, I have met many wonderful people/dogs involved in it and me and Gonzo have had lots of fun with it. I would NEVER discredit a BC breeder for participating in dog sports with their dogs. Of course, it would not be a priority, and the dogs' working ability, temperament, and health is paramount. But, the fact that the breeder also takes the time to compete in dog sports with her dogs, and the fact that the dogs are versatile and can go from working livestock to running an agility course in a day, is just a BONUS, to me. : )
