The Puggle is a cross between the Beagle and the Pug. 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 designer hybrids are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generation crosses. The first Puggles ever bred were bred by a breeder named Wallace Havens.
