[This group is not associated with the National English Mastiff Association in any way.]

The Mastiff Preservation list is the ORIGINAL list formed in 1999 and was formed in an attempt to find, bring together, and educate people interested in preserving, and propagating the less than one percent of the Mastiff bloodlines which do not contain Deer Run. Hopefully we will achieve our goals by finding all of the bloodlines which are left, breeding to the breed standard, and producing dogs of true old English Mastiff type.
