Thank you to everyone! I still don't have those pictures. We were very busy last night trying to spend time with all the pups and kids and we have to be very diligent because even though the two males are only 4 months old, and one got neutered a week ago, they keep trying to mount Isabelle. The one that was neutered is very funny because he can't get to Isabelle because he's too small, so he just humps the air with nothing in front of him. We didn't expect that from him as he's neutered. Is this something they will just always do because it's instinct?? Anyways, have to be very careful, because the one that isn't neutered is big enough to get around Isabelle, but we aren't letting them out of our sight unless we crate them separately. :?
