Although I might have given my potential stud dogs a first experience around 12 - 15 months, that was ONLY ever on my own (suitable) bitches, for an introduction, as well as to see what they might 'throw'. Mine were NEVER offered 'at stud to strictly limited bitches' until much later on. And had mine been a breed/my bloodlines with things that needed to be tested for, only after that in any case. Again that first try, on my own bitches, apart.
It might be 'flattering' to be asked, but frankly I'd stick to my guns regarding allowing outside studs. I was always mindful of the '50% responsible for the offspring my stud dogs might produce' that is the case. And for sure, I didn't want my bloodlines mixed up with poor ones!! I did turn away more enquiries, than I allowed - bearing in mind that if anything unwanted does appear, it's ALWAYS the fault of the stud dog!!! LoL
If you know the people involved here, and the bloodlines of their bitch I suppose it might be a useful experience for him. You'd have to waive the stud fee, at least until a litter (of more than 2 puppies at that) is on the ground. I would never charge, or expect to be charged, to use an unproven male. Frankly if this person wants to use your male because she likes his type/bloodlines, she'd be far far better to go to the sire of your male!!!
