Yorkies are prone to portosystemic shunt (a blood vessel defect that lets toxins bypass the liver), tracheal collapse (a flattened windpipe causing a dry, honking cough), and patellar luxation. Dental crowding from their small jaw also makes periodontal disease common — regular dental care matters more than for larger breeds.
Small, frequent meals of a quality small-breed formula; toy breeds are prone to hypoglycemia as puppies, so consistent feeding matters especially early on.
The long, silky coat (grown out) needs daily brushing to prevent matting, or can be kept in a shorter, lower-maintenance "puppy cut." Regular dental cleaning is especially important for this breed.
Intelligent and trainable, but that terrier stubbornness can show up — consistent, positive-reinforcement training and early socialization help offset a tendency toward main character energy in small dogs.
The Yorkshire Terrier was developed in 19th-century England by working-class mill workers in Yorkshire, who bred small terriers to catch rats in textile mills and mines. Despite the toy-sized, glamorous coat it's known for today, the Yorkie is classified in the AKC's Toy Group but carries genuine terrier grit and instincts.
Yorkies are known for a big personality in a tiny body — spunky, confident, and often unaware of their small size, which is part of the charm but also means early socialization matters.
