I'll try to answer what I think you are asking - however your reasons for asking are not too clear!
If you have a male dog, it is unlikely to be wanted as a stud dog unless it is a very good specimen (as in having won top awards at shows) or it has rare bloodlines in a breed that has a small genepool. The breeder of your dog would be the best person to tell you whether your dog is likely to be wanted as a stud dog, and then it may only be on the very odd occasion.
A 'proven' stud dog is one that has actually produced a litter of puppies, which means that it is capable of mating a bitch and fertile enough to produce offspring, Some dogs never manage to mate a bitch even if given the chance, and some do manage it and don't produce puppies. Some produce offspring but they are not good enough quality for them to be shown or bred from. The difference between a dog and a bitch (no, silly I know the physical difference) is that a bitch can be taken to any number of different dogs, but a dog has to be chosen by the owner of a bitch, and they have a lot more choice, and most breeders would only choose a top quality male.
Also most breeders would use a novice dog on a bitch that had already had a litter, or an experienced dog on a maiden bitch. Believe me, it is not so simple as putting a dog and bitch together (unless of course your bitch gets out and finds the local crossbred romeo!).
As for the arrangement about stud fees/puppies this is between the owner of the bitch and dog to decide, but the usual way is for the bitches owner to pay for the 'service' of the dog, and if the bitch 'misses' (does not have any puppies) then they get a free return mating. Personally I don't take a stud fee until puppies have been born. Some people have a puppy back instead of a stud fee, but this is entirely up to the breeders to decide. Unless you know the other person extremely well (and trust them!) then get everything in writing.
