Murphy tried to hump Daisy the first time they met, even though he was only 10 weeks old. She set him strait that she's not that kind of a girl and it's been OK ever since. He was neutered as soon as he was 6 months old, and I think a little piece fo my sould died that day, but better that he just not know what he's missing out on.
I don't know a better answer than to just knock 'em off quick and keep 'em apart until you do.
...and yes, that hurt me to say it. |
