Years ago I had a litter of Irish Setters and gave my then bf now dh pick of the litter. Of course he chose the largest/beefiest male. Well as it turns out Joshua was Cryptoid and I do believe that he was mentally challenged as well. Anyway, when it came time to have him deballed, the bf now dh couldn't harbor the idea of him losing his "man toys" so we taked our vet into doing a vasectomy -- he removed the retained testicle and then just did a snip snip on the other. I wish I had known about Neuticles -
Neuticles.com - back then

I would not recommend it - I admit it was a mistake -- Joshua would have made a much better pet without the male hormones raging through his 100+ lb. body.
