Male English Mastiffs

Jethro

Jethro is our silly boy! He is the youngest of our males and thrives being around his canine friends as well as the family. Jethro is a typical English Mastiff, very affectionate, loving, patient and very laid back. He has become a dad now and loves his puppies once they start running around. Jethro is not quite sure of them when they are newborns. His Temperament is amazing as is everything else about him. Jethro is genetically tested for everything currently available.

As Mastiffs tend to have a natural protective instinct, he knows his job well and greets visitors a little bit on guard and then with slobbery kisses. We love having Jethro as part of our Thunderbolt Mastiffs family.
