Hmm fake certs are easy to obtain, Certs doesnt guarantee the "pureness" of a certain breed.
There has been a well know case, a well known dog shop in Penang that produces its own certs. The owner is a "somebody" in the dog arena. I bet many other petshops do the same thing.

Dogs with certs are sold with a higher price, while dogs without certs are sold cheaper. I don't really think certs are necessary unless your dog is for show or breeding. If I m not mistaken a real cert contains the dog's lineage, that includes the dog's parents, grandparents etc...

Plus MKA is just an organization which takes money and produces the cert, its not somesort of Gov body that can guarantee purity of a breed.
