The Bullmasador is not a purebred dog. It is a cross between the Bullmastiff and the Labrador Retriever. The best way to determine the temperament of a mixed breed is to look up all breeds in the cross and know you can get any combination of any of the characteristics found in any of the breeds in the hybrid. Not all of these designer hybrid dogs being bred are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generation crosses.
Cody the brown brindle Bullmasador (Bullmastiff / Labrador Retriever mix breed dog) at 3 years old
Bruiser the Bullmasador (black Lab / Bullmastiff mix) at 6 weeks old—"He is a big ball of energy and I can really see the Lab traits coming out in him—he loves to watch birds and chase bugs! His bark started out as a little squeak but has gotten very deep lately. I know he is going to be very protective of us because when he is not in the crate he lies in the way of our front door. He's our little man."
Bruiser the Bullmasador (black Lab / Bullmastiff mix) puppy at 4 months old
"Here is Bruiser at 2 years old. He is a very loving dog and adores playing fetch with his Kong. His favorite thing to do is cuddle up in your lap—he tips the scale at 82 pounds! He has a great personality and wants to play constantly. He is extremely protective of our home—he will definitely let you know when someone is approaching. I could not have imagined a sweeter, happier dog and we have even learned to overlook the drooling. My hubby watches Cesar religiously—he thinks the "CHHHH" is great for getting the dogs to stop doing something they shouldn't be doing."
