Not all dogs that look like Puggles are true Puggles, with 100% pug and 100% beagle parents. Many breeders are performing "multi-generational breeds," with 25% purebred and 75% purebred parents.
There are both drawbacks and benefits to the multi-generational breeds. Certain traits such as non-shedding or unique fur characteristics may be emphasized in later generations, but the vigor of the breed if lost with each successive generation, too.
So make sure you know the exact pedigree of the dogs from any potential breeder, and check references as well as feedback from past customers. Ask around, and if something doesn't seem right to you, don't hesitate to head for the door. You're doing everyone a favor by not supporting a sketchy breeder!
