"This is my dog Tasha. She is 1\2 Jack Russell Terrier and 1\2 Miniture Schnauzer mix. She's very loving and smart and does not know how small she is."
The Mini Schnauzer Jack is not a purebred dog. It is a cross between the Jack Russell Terrier and the Miniature Schnauzer. 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.
