"This is my dog "Taz". I got him from the SPCA. He is a Bullmastiff / Basset Hound mix. He has a definite personality and loves to play ball. He hikes his football through his back legs. He is loveable but also protective. He is also extremely smart but yet stubborn."
The Bullbasset Mastiff is not a purebred dog. It is a cross between the Basset Hound and the Bullmastiff. 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 either breed. 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.
