Where does the BoShih come from?

The BoShih is part of a growing trend in deliberately bred mixed dogs called Designer dogs. Accidental mixed dogs have been around for ever, when purebred purists turn their nose up at so called mutts they are conveniently forgetting that purebreds all come from a history of mixing breeds. But designer dogs are different in that most of the time that first generation offspring is the aim. But what you do have to be careful of in this market are that a lot of breeders of these dogs are puppy mills and bad breeders. They get away with their terrible practices because people buy from them. Make sure you are careful who you buy from.

Despite the selling argument of getting the best of two purebreds in one dog, the genetics in this kind of breeding cannot be controlled or predicted. Determining what a dog will look like or be like in terms of personality is not as easy to do as with purebreds. Here with no origins known about the BoShih we can look at the parents for an idea.

The Boston Terrier

In the late 1800s the Boston Terrier became one of the first non sporting dogs bred in America. What went into the mix is not exactly known and at the time he was not called this name but in fact was referred to with a variety of names. When his club was formed they eventually changed his name to what we have now. They were popular in the early 1900s and are a mascot of a number of schools and places in America.

This dog is affectionate and clever with an even temperament. He can also be very lively so needs plenty of exercise. He can be stubborn though so when it comes to training he is not always easy and it needs to consistent and you need to be patient.

The Shih Tzu

The Shih-Tzu is an old breed and comes from either Tibet or China. They were treasured as companion dogs and were referred to as little lion dogs. They were described as being docile, intelligent and happy. The first breeding pair to leave China and come to England happened in 1928. In 1969 he was recognized as a breed by the American Kennel Club.

The Shih-Tzu today is still a great companion dog. He wants to please and be with you, he is very affectionate and loves to receive it too. He will spend as much time as he can in your lap and is a happy little dog when he has lots of attention. He can be lively and likes to play and is friendly too.


The BoShih is an alert and curious dog who can be playful and is usually very cheerful. She is an intelligent and sweet dog who loves people but is sometimes shy at first around strangers. She is a great family dog as well as companion as she gets along with everyone. She is affectionate and loving to her family too and loves to cuddle and is eager to please. She is an active and energetic dog who loves interacting with people and will bond strongly with her family. The BoShih will need a lot of attention from you and needs a family who are home more than not.

What does the BoShih look like

This dog is a small dog weighing 10 to 20 pounds and measuring 12 to 16 inches tall. She has a curly long tail or a shorter one, a face that is somewhat flat and flappy or upright ears. She has a compact small body and legs that are in proportion to the rest of her. Her head is rounded, her nose is black and her eyes are dark and also round. Her coat can be short, medium or long, and it can be soft or wiry. Common colors include brown, white, black and tricolor. Some BoShih have a beard on their chins.

Training and Exercise Needs

How active does the BoShih need to be?

She is a fairly active dog so will need regular exercise to stay a healthy weight and be happy and better behaved. She would love trips to a dog park, she loves to run and is very fast, and she also usually enjoys swimming. She is strong for a little dog so be prepared! She loves to dig too. She is good for apartment living due to her size but she does have a lot of energy so needs a couple of brisk walks a day at least. If she has access to a yard that is a great bonus and a place for her to explore and play in.

Does she train quickly?

She is moderately easy to train so it will come gradually not super quickly but it should not be harder than most dogs. She is stubborn sometimes and that can slow it down. House training varies, some owners find house training is harder and some find she learns it very quickly. Early socialization and training are important to bring out the best dog she can be. Be firm but consistent and fair when training. Keep your voice patient and positive and offer rewards and treats and praise to encourage and congratulate her.

Living with a BoShih

How much grooming is needed?

The BoShih has moderate to high grooming needs depending on the coat she has. Sometimes she can be a frequent shedder so needs a lot of brushing every day as well as vacuuming up after her. Other owners find she is more low to moderate when it comes to shedding. She is not suited to owners with allergies. She should be given a bath just when she gets really dirty and always use a dog shampoo only to clean her. Her ears should be cleaned using a dog cleaning solution and a cotton ball. Just wipe the sections you can see once a week and check for infection. Do not insert anything into the ear. Her teeth will need brushing regally, preferably two to three times a week. There are dog toothbrushes and pastes you can use. If you start all of these things from a young age she will get used to it. Her nails need to be clipped too when they get too long, being careful not to cut into the quick. Long haired BoShih may need semi regular trips to the dog groomers to have her hair trimmed.

What is she like with children and other animals?

She is very good with children, other pets and dogs. Early socialization and training help with this though she tends to be naturally more inclined to get alone with everyone. She is small though so should be supervised with small children who do not know how to take care with smaller more fragile animals. Teach the children straight away how to interact and play nicely with her.

General information

Her ability as a watchdog is something that also seems to vary depending on which parent she leans more towards. Some owners find she will bark to alert them if something is wrong or unusual and others say she will not. Her barking otherwise is rare. She will need to be fed ¾ to 1½ cups of good quality dry dog food each day, split into at least two meals.

Health Concerns

There is a chance she could inherit issues from her parents or be more prone to certain issues such as Patellar luxation, Kidney problems, bladder problems, liver problems, eye problems, Umbilical hernia, heart problems, deafness, brain tumors, Allergies, hip dysplasia, ear infections, dental problems, snuffles, reverse sneezing and Megaesophagus. To lessen the chances of having a dog with hereditary issues visit the puppy before buying and ask to see parental health clearances. The BoShih may also breathing problems and snore due to her short muzzle. This means she can easily overheat so needs watching. She also likes to overeat so watch her weight.

Costs involved in owning a BoShih

A BoShih puppy could cost between $300 to $550. Other costs include getting a crate, collar, leash, carrier and other basic essentials that she will need. She also will need blood tests, deworming, shots, micro chipping and when old enough spaying. These costs come to between $360 to $400. Yearly costs for basic medical needs like check ups, flea prevention, shots and pet insurance or savings come to between $435 to $535. Other costs that are not medical in nature such as food, training, grooming, toys, license and treats come to between $530 to $630 a year.
