not going to breed our dog who will be 1yr old in March.
When he's with other dogs the humping is OUT OF CONTROL.
1) any advise on how to discourage this? methods?
2) what is the best age for allowing their hormones to take their effect on his phsyic (and avoid making him "leggie")? but no letting the humping drive continue on and on...?
Your pup is hitting puberty, they are worse at that age, does not last forever. I just give them a tap and No or Ahhh and discourage it. I would not neuter until the dog is fully mature or between a yr and 2.
I've seen more humping from the female dogs in my house than any of my boys. Demonstrated by my little ACD:
Yes just about every vet I have ever talked to wants you to neuter/spay at 6 months. Even my vet who knows we do performance events said I should spay Java, I said no way. I plan on doing conformation, but even if I was not doing conformation I would wait. It seems that there are alot of indications if you spay before they are mature they will get leggy stretching those tendons which could cause issues later on.
And yes, the females hump too. Somewhat it is dominance. My labs were bad trying to hump. My older GSP has never humped and will absolutely not allow it from anyone else. She keeps everyone in line about it. Perhaps I could loan her out to you. Just kidding. I love that dog too much to send her anywhere but my house.
