A good stud dog would be one well matched to herself and her pedigree as none of us know your bitch we could not possibly recommend anything. The best person to do that would be your dogs breeder. A good stud dog will of course have had good results from all recommended health screening for the Bearded Collie and of course the owner of a good one would not permit his use unless your bitch had had the same as well as expect her to be a good example of the breed capable of being placed at shows if not actually having done so. If you have not shown your bitch, again, her breeder will be able to advise as to her suitability :)
