Jacairn (Designer Dog)

The Jacairn is not a purebred dog. It is a cross between the Cairn Terrier and the Jack Russell Terrier. You may be able to determine the temperament of mixed breeds by looking at all breeds used in the cross. You could get any combination of characteristics as all designer dogs are not necessarily 50% purebred to 50% purebred. In fact, it is very common that multi-generational crosses will be employed based on the breeders wish to achieve certain goals.
