Oh dear, it looks like I've spoken too soon. It's been two days since the change in behavior started, and he had only been trying to hump his dad since then... but just now, he obsessively started trying to hump me. I couldn't even play or do anything to distract him from it - humping my arm was all he wanted to do. I just put him in his crate (not as punishment, just because dinner's ready for us and I was going to put him in there anyways). He's only four months old! I feel so bad, like we taught him this behavior! Uggh, I feel awful. I guess now I get to go search through all the threads about humping to try and figure out what to do.
I was hoping I wouldn't ever have to search that. :-(
