"This is Lucas, my Scottish Terrier and Cavalier King Charles mix. He has a great temperament and is very friendly. His favorite things are chasing squirrels and snuggling with his ruby Cavalier sister and Blenheim Cavalier brother that were adopted from Cavalier Rescue USA."
The Cavottish is not a purebred dog. It is a cross between the Cavalier King Charles Spaniel and the Scottish 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.
