The only recognised kennel club in India in the KCI (Kennel Club of India) The website is www.thekci.org
no other club is recognised in India. Try getting a hold of the parents papers to see also. Otherwise you can register your dog with unknow parents. Speak to the KCI for procedure.
Just because it is not registered with KCI does not mean that it is not pure breed. Hope u saw the parents when u bought the pup and they looked like Golden Retreivers.
