I don't understand something..listed on this person's website under Nursery Section is this:
Our pet boys are typically neutered at 10-12 weeks of age so they never
figure out they are a boy. They should never lift their legs
or mark because they are neutered before they ever get the adult male hormones.
This eliminates most of the issues people have with male vs. female pups
????10-12 weeks of age????
