Gage has started humping... ugh. Poor Bo, he humps that boy senseless. And he's starting to attempt to mark things indoors, even though he is house trained. So I'm getting him neutered in about 2 weeks. Must be time, LOL!
Sam and Bo were both insane markers indoors, and Sam was also a massive humper. Neutered them both, and within about 2 months, they never marked indoors again, and Sam never humped either.
I think the biggest one was Frankie. Oh dear lord that boy marked in the house 50 times an hour. He marked EVERYTHING. And he was so obsessed with Sam, that Sam couldn't live a life without Frankie on top of him. He'd even hump Sam's kennel with Sam in it.
We had Frankie neutered like... probably a month to a month and a half ago, and the humping is completely gone. He couldn't care less about Sam. And the marking is almost completely gone too. He attempts to mark maybe once every few hours, as opposed to 50 times an hour. He can even be let loose in the house without his belly band now, under supervision. And he's like 15. At his age I didn't think neutering him would work THAT well, but hey, I ain't complainin'!
Give Finn a huge, gentle hug for me!
