Hi everyone! I'm new here, so will introduce myself first. I'm Bianca, living with my partner and three kids in the Netherlands. Last summer we added our new Border-collie friend Pixel to our family. He's really the best! Playful, stubborn, sweet and caring. With his 7 months he's still a puppy trying to get things done his way of course. Our Pix has not been helped, but thus far this hasn't been an issue. We recently came across a crossbreed Australian Shepherd x Border Collie, who we most likely will adopt. It's a 7 month old bitch not being helped either. For now and probably not ever, it's not the plan to breed with our dogs. Since they're both young and breeding is not really our expertise, I'm wondering what we can do to prevent them from breeding. I know that bitches won't get anticonception until after their first period. But I want to prevent her getting pregnant by accident, before she even got her shot. Definitely not at such a young age. As long as there is no medical cause, we don't want them sterilized or castrated. So we're looking for the best option possible to prevent pregnancy before her first shot. Can't and will not keep them separated during the day, but can at night when there is no supervision. Is there anyone who could advise me on this? Thanks!
