The
Patterland Terrier is not a purebred dog. It is a cross between
the Patterdale Terrier and the
Lakeland Terrier.
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.

/ Lakeland Terrier Hybrid) "Alfie is bold, exuberant and feisty. Can be a lap
dog, but tends to not stay for long, if there are noises etc..."
