One of the advantages of designer dogs is the sheer number of varieties available. Over 200 different hybrid combinations exist, which means there is a designer dog for every taste. Most of these hybrids are small and designed to have good personality combined with adorability.

Designer dogs are created to fit every need — from pocket-size dogs for easy travel to low-shed dogs for those with allergies. Many of these designer-dog creations are free of some of the traits that can make life difficult for the purebred dog. For example, some purebreds, like the Pug, have a very short snout, making breathing difficult. But the popular Puggle — the hybrid of a Pug and a Beagle — has a longer nose while still maintaining the Pug’s wrinkled forehead and loopy gait.

Many hybrid breeders claim their dogs have hybrid vigor, a strength that comes from having parents of two different breeds. The offspring of two different breeds rarely inherit genetic defects, because the bloodlines aren’t as close as those of purebreds. Purebred dogs often have inherited traits that can cause genetic defects. For example, many retriever breeds tend to have cataracts or epilepsy, many large-breed dogs have hip dysplasia, and many small-breed dogs are prone to dental problems. Mixed-breed dogs rarely inherit these genetic defects, because their genetics are more varied. (Incidentally, this is true of all mixed-breed dogs, not just designer dogs or hybrids.)
