Xoloitzcuintli (Mexican Hairless Dog)
The Mexican Hairless dog, also known as Xoloitzcuintli or “Xolo”, is a unique breed known for their loyalty and affectionate personality. Their roots go back to Mayan, Colima, and Aztec Indians. Xolos come in three sizes: toy, miniature, and standard, as well as in hairless and coated varieties. Today, these dogs are cherished as gentle, devoted companions.

Are you interested in this breed? The OFA, working with the Xoloitzcuintli Club of America, recommends the following basic health screening tests for all breeding stock:
- ACVO Eye Exam
- Cardiac Exam (Basic or Advanced)
- One of the following: OFA Hip or PennHIP for both Standard and Miniature sizes, Patellar Luxation for Toy size.

Dogs meeting these basic health screening requirements are issued Canine Health Information Center (CHIC) numbers. For potential puppy buyers, CHIC certification is a good indicator the breeder responsibly factors good health into their selection criteria. However, additional testing that is relevant to the breed is always encouraged.

Are you looking for DNA based disease tests for your dogs?
The OFA has a variety of DNA tests available for order that allow owners to safely collect DNA samples at home. Samples are then sent to the University of Missouri College of Veterinary Medicine where the samples will be processed by the Small Animal Molecular Genetics Lab. Results will be forwarded to the OFA, and the OFA will issue the resulting report to the owner.

Additional tests can be found through other labs, such as UC Davis, Embark, PawPrints, GenSol, AKC DNA+Health, Mars Optimal Selection, etc.
