How to Breed Chihuahuas and Shih Tzus

Chihuahuas mixed with shih tzus, or ShiChis, are small, sweet-tempered little dogs. The breed is recognized by many hybrid dog registries, including the American Canine Hybrid Club and the Designer Dogs Kennel Club. Mixed breed puppies can end up with qualities of either breed, including health problems. It is important to know the health history of both potential parents as well as the other dogs in the pedigree. Never breed a dog that has health or behavioral problems.
