And of course he should be hip scored, and eye tested for PHPV!
All these testes are likely to cost you around £250, and then you may find he won't perform!
There is of course your responsibilities to the breed and the pups, will you be abole to help the breeder out if any of the pups need rehoming? Also with such a large breed is his temperament really rock solid, neither aggressive or nervous in any way, and do you know that the bitch is also? If there is even a shadow of doubt over this aspect then don't breed from him, as how would you feel if one of his pups had a temperament problem, and either harmned someone, or had to be put to sleep, how would you feel?
I would also seek advise from your dogs breeder, as to wheteher they think your boy is of a high enough standard to offfer the breed something, and to check if the bitch's pedigree is compatible.
