we are looking for a stud dog for our salt an pepper schnauzer 2 years old breeding for pet not show

Your best bet is to ask her breeder who will know which lines are most likely to give you the healthiest, best quality puppies. Some lines, when put together, can be disastrous. :( If the breeder won't help, then contact the breed club for advice.

Remember, whatever market you're aiming for, the purchasers deserve healthy puppies, whether they're for show or pet!
