We're waiting until she's two (it's actually in our breeder contract). Even if it wasn't in the contract, though, everything that I've been reading on early spaying scares me to death. And honestly, if you think about it, it just makes sense to wait. Think of all the hormonal and growth issues we go through during puberty.
I feel really lucky that we haven't gotten any pushback for waiting to spay. Our regular vet is totally on board, and even our daycare place thinks it's the best idea (though they're really sad that she won't be able to go to daycare after she's seven months).
From what I've read and learned, though, dealing with a bitch in heat isn't too troublesome from the mess standpoint. You just need to be super careful about never leaving her alone where male dogs can get to her, but with a little vigilance it shouldn't be that bad. I hope. :lol:
