My breed of choice is greyhounds, which are such gorgeous sweet, gentle, undemanding dogs, and they have great personalities, some are real clowns. I have to say that I'm very anti racing for many welfare reasons, including the "culling" of some of the poor dogs that don't make the grade, which is disgusting and heartbreaking. 😠 However, they are bred for speed, health and temperament, so aren't prone to the health conditions that are so common in many breeds, so the ones lucky enough to end up in loving homes after racing generally lead long, healthy lives.
I abhor the practice of breeding fashionable dogs to basically suffer disabilities and ongoing health problems, like French bulldogs, because people think they look cute. I can't think of anything less cute than a poor deformed dog struggling to breathe all the time, it's incredibly cruel and must be very distressing to witness. At least I know my dogs have come from healthy stock, have been well socialised and will hopefully have a good quality of life. They're rarely difficult/neurotic, though a few are real "spooks" who need careful handling and training. I'm also very happy to be able to give a home to a dog that's been discarded once it's racing life is over, which is so wrong. I'll be very glad when greyhound racing dies out, as some of the dogs get a very raw deal, but must admit I hope the breed doesn't die out, because they're the most beautiful souls. I can't imagine having another breed now.
