Puggles are not a purebred dog, they are a crossbreed between a Beagle and a Pug. They are considered to be a designer dog in many ways, and like many of these designer crossbreed dogs, not all of them are 50% purebred to 50% purebred. Breeders will often breed multi-generational crosses, so some may be more Pug and some may be more Beagle.
Puggles are a relatively new breed of dog, first bred in the 1990s. The parents of a Puggle must be a male Pug and a female Beagle. This is because there are often a great deal of complications that can arise when the male dog is larger than the female.
They are small, heavy-bodied dogs with loads of energy and if you train them well they can be an excellent addition to your family, they will get along with you, your family, your kids, and even your other pets.
