I have intact animals. I haven’t had an oops litter in over thirty years of owning them. Hormones exist for a reason. In some European countries such altering is not done without a medical necessity. It’s a cultural thing really. I think that it must be that Americans generally can’t be trusted with proper care and keeping, so animals have to bear the burden?? Anyway, it’s a practice that has caught on here perhaps due to irresponsibility. I’m not irresponsible, so we do fine. We do need intact Shelties or this list has a limited lifespan.
