You may not find someone who has bought from this kennel, but what you should do is you should go visit the kennel yourself and see both parents and the mother with the pups. If you like the parents then that is what the pups should generally turn out to be. Also see both parents KCI papers and also insist on seeing the puppy papers or atleast the registration papers applied for letter and check with KCI regarding the application given.
Ask for people who they might have sold pups to in the past and go have a look at those dogs and take feedback from those owners also. Otherwise distance is no problem these days and Mr. Vaid in Delhi seems to have some nice imported Goldens which he has started breeding.
