I started Grenfel Boxers in 2011 with my second boxer purchase (my first was when I was 21) from Tanoak Boxers.
Why Tanaok? - Well known and credible, many years experience and tracking.
Today I'm running a full house of Tanoak blood. With all the testing from Tanoak and all the testing I have done, the ability to trace back in history keeps this line healthy as possible I believe these bloodlines are far superior.
