The Puggle is a crossbreed. Opening your heart and home to a crossbreed is like opening a beautifully wrapped package on your birthday: you never know what’s going to be inside. It’s often assumed that a crossbreed will combine the best of two or more breeds, but genetics doesn’t always work that way. The way genes combine and express themselves is not always subject to a breeder’s control, even less so when two different breeds are crossed. That’s something to keep in mind before you lay down lots of money for a dog that you have been assured will be hypoallergenic or healthier than a purebred. It's hard to imagine a more incongruous mix than the loving, playful, lap-sitting Pug and the independent nose on four legs known as the Beagle, but that's what a Puggle is. While both breeds are short-coated, small, cute, and popular, that's about all they have in common (vetstreet.com).
