"This is our dog Josie at 9 months old. She is a Jack Russell Terrier / Basset Hound mix. She is beautiful and very loving."
The Basset Jack is not a purebred dog. It is a cross between the Jack Russell Terrier and the Basset Hound. 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.
