Reign is adorable!! I had Huey fixed at 6 months, 1 day. Unfortunately, the leg lifting and marking had started by 13-14 weeks and was only slowed by the neutering(pees on every
other mailbox on walks, not
every one). The humping has net really been a problem with anything other than 1 particular toy. So, i would go with whatever feels right to you and your vet.
