the short version is that they aren't strictly Driver bred dogs. I have a gyp named Pet that is heavily linebred on the Buster X Ginger dogs of Bob Owens. She also shows a single instance of Cowboy and thru Bob's old Rowdy dog a little extra bit of Jordan's Henry and Driver's Jenny. Pet is the momma of these two pups.
the weird coloration of the male pup in those pictures is from his daddy (now deceased) that I got out of Round Rock, Tx with the help and generosity of this man.
This is my friend Jessie Jones. Some of you might be familiar with the story of the "old, black dog man from the Coffield ranch in Rockdale" . . . who produced Owens' Liz. This is him. Now 84 years old.
