dog sterilisation

[happy_face]

Was just wondering if you sterilised a male dog would it prevent it humping every other dog around? Or doesn't that change anything?

[ipek]

Not in my experience it doesn't!  I even had a sterilised female dog that insisted on humping other dogs (oddly enough, they were usually female too)

Didn't stop my male cat humping anything it could, cushions, my leg........................................

I had a vasectomy 22 years ago and it hasn't stopped me :-)
By the way I don't mean dogs.

Castration and Vasectomy are quite different. Castration is the surgical removal of the only organs producing sperm and the main source of testosterone, the hormone that acts on the nervous system to promote male arousal and at a cellular level physical male characteristics. Vasectomy is a procedure to disconnect the vas deferens, a small tube along which sperm travel fom the testes to the urethra. This will not affect sex drive or male characteristics.

If castration is performed after male behaviour (you know what I mean!) has developed, then it will not stop it. For example cats still go through the spraying response, but cannot produce the really smelly stuff. It seems that the testoterone triggers a behaviour response that is learned and then repeated without further need of the hormone.

Female animals that are speyed have their ovaries removed thus denying them the main source of eostrogen, the female hormone, and may display male behaviour. Both sexes produce testosterone and eostrogen and it is the balance of the two that determine sexual development and behavour.

Whoops, should be oestrogen. Silly me!

I had my dog "done" when he was two.He was dreadful up until then.Any scent of a female and he was off.Then he would howl and chuck himself at the door ,wouldn't eat his food and all sorts of other naughty behaviour.A few months after the op he was a different dog.He is now ten and we have never had any trouble with the behaviour you describe.Other dogs have tried it on with him at times but he gets the hump (pardon the pun)and tells them where to go!!
