I would say yes, as he would need to be over a year old when first used, and been hip scorede, and eye testede if appropriate (most breeds have some eye disease that needs checking for), he may also need heart and elbows checked, depending on the breed. A;so as he isn't mature yet, you want to see if he realises his early potential.
If it is a popular breed, I would alos be careful of the sort of people that have asked to use him. you want to be sure that they would be breeding with thee breeds best interests in mind, not just to produce litters for sale. will they take special care to home the puppies proiperly, and also will you be prepared to help if any of the pups require rehoming at a later date, as you would be as responsible for bringing them into the world as the bitch owner.
