desexing or not

Hi everyone will getting my boy desexed will he stop trying to
do my female who is already desexed

Short answer.....no.

Humping is not necessarily a sexual behaviour & if your dog has been doing it for a while he'll likely carry on as it's a habit/learned behaviour. I'm not saying don't do it, just don't expect it to stop the humping!

The only real way to stop it is by training, I'm afraid.

Thanks for the advice
