Our vet is also recommending between 5 and 6 months to get Ozzy neutered, before he starts marking and humping.
He's 4 1/2 months now and so far the only thing he's humped is the ONE other yorkie we met at the park. A very cute little girl, so I couldn't really blame him
and she was, thankfully, fixed. It was actually really funny, because every time he got near her he would hump the grass
