Hi guest
Seeing your sibe *running nice or trotting like a horse* is not a good enough reason to breed him

Firstly is he AKC registerd? Is he close to the breed standerd? What tests are you planning to have done (hips & eyes?).
I would sugget you go along to local shows and talk to breeders if you are lucky they may take a look at your husky and tell you whether if he is show/breed quality, I would suggest you show him to prove he is worthy of the breed standerd (its great fun for you and the dog), then when you have done all th e above go about seeking a suitable mate that has also done all of the above................
Its a lot harder than sticking two dogs together and waiting for the outcome............... hope this helps
You could try looking on the Siberian Husky Club website
Not sure if they have one in the USA ( I bet they do) here is the address for the UK one
www.siberianhuskyclub.co.uk
they have loads of advice on there
