Yorkie shih tzu puppies are one of the favorite dog breeds. Indeed, statistics show that they are the second most popular.

Yorkies have an interesting history, and looking after them is fairly easy, but they are also prone to some problems. Yorkies originate from Yorkshire England. Their ancestors were actually Scottish and other terriers that were migrated into England by Scottish immigrants.

These breeds were initially used for rat control, which was a major threat to humans those days because they spread diseases such as the plague. Ultimately, these dogs were bred together, and the breed we know as the Yorkie materialized.

Yorkie shih tzu puppies are sometimes called toy breed dogs, because of their tiny size. Their average weight is about 7 pounds. However, these dogs can at the same time be very hostile, and they make great watchdogs.

Yorkie shih tzu puppies are mostly black and tan, and their coat does need grooming. Nonetheless, experienced groomers aver that they need trimming of their fur about once each month, to keep the coat from heaving down and out of the dogs' eyes.

Yorkie shih tzu dogs have minimal shedding because of the type of their fur. These dogs are less allergenic than other breeds, and they can serve well in cases where people may be allergic to dogs. Just like other dogs, they need high quality nutrition and fresh, clean water in plenty, to keep them in good health. Regular veterinary checkups should be part of their health care program.

However, Yorkie shih tzu puppies are also prone to some problems. As a result of their tiny size and minimized amounts of body fat, these dogs can get a condition referred to as hypoglycemia, a manifestation of low blood sugar levels. If your dog seems restless, and appears to be in a coma, it could be having this condition, and quick medical attention is necessary.

Further, genetic information on Yorkies show that they are prone to a condition called hydrocephalus, which is a situation whereby they have a huge buildup of fluid in the brain. This condition is lethal. However milder forms of this condition are actually welcomed by some breeders and such dogs are sold as apple head Yorkies.

Yorkie shih tzu puppies are generally interesting types of dogs, with interesting origins and characteristic traits. Due to their traits, they are among the most favourite dog breeds known today. In the United States, statistics reveal that they are the second most popular dog breed in the entire American nation.
