Shorkie Dog: What a Shih Tzu–Yorkie Mix May and May Not Inherit
A Shorkie is a cross between a Shih Tzu and a Yorkshire Terrier. Because it is a mixed-breed label and not a standardized breed, the label alone doesn't tell you a puppy's adult size, coat, temperament or health. PetMD notes that the AKC doesn't recognize the Shorkie and that there is no breed standard to define its temperament or appearance. Hill's Pet Nutrition says it can be hard to predict which parent a Shorkie will take after. The most reliable information comes from the actual parents, the breeder's or rescue's records, and how a particular dog behaves.
What the label does and doesn't tell you
"Shorkie" describes ancestry, not a predictable outcome. The parent breeds' standards can work as rough blueprints, but they are a starting point for questions, not a forecast.
Published size ranges differ by source. PetMD says adults typically stand 7–10 inches and weigh 7–16 pounds. Hill's gives 5–15 pounds and 6–14 inches. The sources also disagree on lifespan: PetMD estimates 10–18 years from the parent breeds' ranges, and Hill's lists 11–16 years. These are estimates borrowed from the parents, not measured Shorkie data, so treat them as rough context and not as a promise.
Two plausible adults
These two profiles are illustrative, not real dogs. They show how far one litter label can stretch, using traits the sources describe for each parent.
Dog A leans toward the Shih Tzu side. It may have a rounder head, a shorter snout and a slight underbite, as Hill's says a Shorkie might inherit from the Shih Tzu parent. A shorter nose can bring airway problems, a higher risk of heat-related illness and snoring. Shih Tzu eye problems may also carry over; PetMD lists cataracts, dry eye and progressive retinal atrophy as conditions Shorkies may inherit. The household questions for Dog A are heat management, harness use and eye checks.
Dog B leans toward the Yorkie side. It may be smaller and more spirited. Hill's describes Shorkies as half terrier, which can mean high-strung, intelligent, a high prey drive and digging. PetMD describes Yorkies as confident and spirited. Hill's also notes that tiny bladders and a stubborn streak can make house training harder. The household questions for Dog B are size and fragility around young children, training consistency and time alone.
A puppy can show features of both profiles, and its adult coat, size and behavior may differ from how it looked at eight weeks. That is why individual observation matters more than the breed label.
Health questions to raise, not conclusions
These are screening and preventive-care topics to discuss with a veterinarian. None of them is a diagnosis, and a Shorkie may never develop any of them.
-
Teeth. PetMD says periodontal disease is common in all dogs and especially in small and toy breeds. It recommends brushing at least three times a week plus regular cleanings. Hill's also advises regular dental checkups.
-
Airway. PetMD says both parent breeds carry an increased risk of tracheal collapse. The typical sign is a recurring honking cough that can worsen with exercise, heat, excitement or eating, and a harness is usually recommended over a collar. Hill's flags brachycephalic airway problems for dogs with a short nose.
-
Eyes. The Shih Tzu side brings cataract, dry eye and progressive retinal atrophy concerns. Hill's also mentions glaucoma and tear staining. Keeping hair away from the eyes is suggested.
-
Knees. PetMD notes patellar luxation is more common in small breeds such as Shih Tzu and Yorkies. Many dogs have no problem, though severe cases may need surgery.
-
Liver and blood sugar. PetMD says portosystemic shunts are relatively uncommon but that both breeds are predisposed. It also says puppies need frequent meals, three or four a day, to avoid hypoglycemia. Hill's lists hypoglycemia and congenital liver disease as risks.
If your dog has trouble breathing, collapses, or seems to be struggling, that needs prompt veterinary attention and not a wait-and-see approach. Ask your veterinarian which signs in your dog warrant a same-day visit.
On food, PetMD says there is no overarching recommendation for Shorkies. A veterinarian can build a feeding plan based on age, weight, body condition and health, and a complete and balanced AAFCO-approved diet shouldn't need supplements. A "Shorkie formula" is not automatically required.
Records to ask for
Because the cross has no breed standard, the parents' paperwork matters more than the Shorkie label. The Orthopedic Foundation for Animals (OFA) says its Canine Health Information Center (CHIC) program records breed-specific screenings recommended with parent clubs, and that a CHIC number shows required tests were done and made public, not that the results were normal.
For the Shih Tzu parent, the American Shih Tzu Club board voted in 2021 to recommend that CHIC require an OFA/CAER eye certification and OFA patella certification. I couldn't open a current OFA requirements page for the Yorkshire Terrier, so ask the breeder which tests each parent had and look the dogs up in the OFA public database yourself.
A responsible source should be able to show:
-
Identification and health-test results for both parents, not only a general statement that they are "healthy"
-
Veterinary records for the puppy, including exams and vaccinations
-
Adult sizes and temperaments of the parents and, if possible, earlier litters
-
A willingness to say what they can't predict, such as coat, adult size or later-onset eye disease
-
Willingness to take the dog back if the home doesn't work out
PetMD stresses working with a breeder committed to health over profit who does genetic testing before breeding. Shorkies aren't AKC-registered, so there is no AKC breeder listing to lean on. Hill's notes that the American Canine Hybrid Club and the International Designer Canine Registry offer registration, but those registries don't tell you whether the parents were health-tested.
Household fit
This checklist adapts the questions PetMD poses to prospective owners, along with Hill's behavior notes.
-
Grooming time. PetMD says long coats need daily brushing and at least monthly baths. Hill's adds that a groomer visit every six weeks or so may help. A shorter cut is an option if the routine feels like too much.
-
Time alone. Both sources say Shorkies can become stressed or anxious when left alone for long periods, with barking, house-soiling and chewing.
-
Small children and big pets. A dog of this size can be injured by accident, so supervise interactions.
-
Exercise. Around 20–30 minutes a day is the range both sources give.
-
Heat and cold. Hill's says both parent breeds tolerate extreme temperatures poorly.
-
Veterinary budget. Dental care, eye checks and any orthopedic or airway work can add up over a lifespan that may reach well into the teens.
Choose a dog on its observed behavior and records. If the parents' history, the puppy's exams and your household routine all line up, the Shorkie label matters little.
