8. They Bark a Lot
One personality trait of a Yorkshire Terrier is that they bark a lot. This has given them a reputation for being a yappy dog and to some people this is a negative aspect of the breed. However, others see it as a positive feature of this type of dog. One reason for this is they make an excellent watchdog. It is a well-known fact that the presence of a dog in the home can act as a deterrent against crime. When a dog starts barking if an intruder tries to enter your home, they are less likely to commit the crime as the barking will draw attention to them and make people aware that a crime is about to take place. Therefore, some people will specifically choose a Yorkshire Terrier because they bark and can act as a form of security to their home. Some experts argue that if a Yorkshire Terrier is content, it is less likely to yap unnecessarily.

9. Yorkshire Terriers Are Easy to Train
One of the best advantages of having a Yorkshire Terrier is that they are an intelligent breed of dog and this makes them easy to train. One reason they are so easy to train is that it is in their nature to work well without the need for human assistance. The Yorkshire Terrier was originally bred as a working dog and their nature is suited to following instruction. They are easily motivated by food or praise and are extremely quick to learn. According to Stanley Coren’s book ‘The Intelligence of Dogs’, the Yorkshire Terrier is ranked as 27th in the list of the most intelligent dog breeds.

10. Like Humans, They Have Two Sets of Teeth in a Lifetime
Just like humans and most other dog breeds, a Yorkshire Terrier will have two sets of teeth in a lifetime; their milk teeth and their adult teeth. Their milk teeth, or deciduous teeth, consists of 28 teeth. At first, a puppy will have no teeth and their first teeth will begin to grow between the ages of three and eight weeks old. They will then lose these teeth at about four months of age and the second set will grow.

A Yorkshire Terrier will usually have 42 adult teeth. This can sometimes vary but it is not a problem unless it is causes a bad bite. One problem that Yorkshire Terriers have is overcrowding of their teeth because of their small jaws. If this occurs, it can result in poor dental health. They may need professional cleaning by a veterinarian to prevent further health problems.
