Trigger Jackson - Mixed Breed Stud Dog in Tenmile, OR

Trigger is a English Mastiff x Neapolitan cross bred from farm dogs. Im looking for an English mastiff female to create a litter of functional English Mastiffs that still have some size. He is an F4 fourth generation cross, being predominantly English Mastiff. Fifth gens are considered purebred. He does have health testing done, however we have yet to complete OfA hips/elbows, but that will be done before October. He is very weary of strangers, highly driven, and biddable with family. He is sweet, silly, and attentive with his people, but untrusting of strangers, of all sorts, but is very intelligent.
