The Yorkie is all heart and fits in the pocket of any affectionate owner. This small Terrier is a giant competitor in dog shows, and easily displays its pride and self esteem.
The tiny Yorkshire Terrier displays a long silky coat to the ground, blue and tan colored: the hair is shiny and fine, and should be perfectly straight. The head is ornate by a bun, usually kept with a bow or two in its delicate hair. The head is small and somewhat flat on top; the muzzle is not too long; good teeth; small ears, “V” shaped, erect; medium, dark eyes, not prominent, with dark eyelids. The body is very compact in this Terrier toy under 3.5 kg, with a short back and straight upper outline. The forelegs are straight, elbows not in or sticking out; hindquarters straight with moderate angulations; feet in a steel blue tonality, not silver blue or blue with fawn hair, bronze or black. The blue covers the body from the neck to the tail, and the tan at the sides of the head, the base of the ears, the muzzle, the chest and limbs. The tail is docked in half and carried a little over the back, darker colored than the rest of the body.
WHO IS IT RIGHT FOR             
Choose the Yorkie if you can commit to have it with you all day. It is an excellent travel companion, it loves walks, and can be as still as a mouse if needed. 
Every 2.5 kg of the Yorkshire Terrier bursts with a bold attitude. Its miniature Terrier heart has given it a great protective instinct, and a chivalrous bravery that one would associate with a dog 20 times its size. Even so it is a happy lapdog, and loves to be pampered. It is very loyal and a charm to be a part of any family. Don’t spoil your Yorkie, or it will become as biting and paranoid as a politician.
The puppy is born black with tan colored spots, and in time it gets its classical steel blue and tan coat. As any dog, choose it for its good temperament over anything. 
The Yorkie develops slowly, and due to its small size it doesn’t leave home until after three or four months. The puppy is born black with small tan spots at the sides of the head and base of the ears, on the muzzle, the nape, all four feet and under the tail. All black or different puppy hair trait should disappear completely, since otherwise the golden tan color is ruined. Hair roots that are too thick prevent good hair falling. At birth, the ears are dropped, and raise later, usually interrupted by dentition. The puppy hair grows slowly, and the first bow will not be placed until after five months. Usually the hair needs eight to ten months to reach the ground and needs to be put up for its protection.
Even the smallest Yorkie puppy doesn’t know its size. This little devil is fearless. 
Despite it liking laps and pockets, the Yorkie is a lively companion; on it toes, always willing to please.
The Yorkie honors its Terrier breed with its lively, fearless personality. Hair care is very demanding. Abundant brushing and daily combing is necessary, as well as more specific care to achieve the ideal hair. The Yorkie has problems common to other toy breeds, such as knee luxation, tibia dislocation, spine problems and congenital hydrocephalia. Legg-Perthes, a rare disease, has been documented in four to twelve month Yorkies. Eye problems such as dry keratitis, progressive retinal dystrophy and distichiasis are documented. Digestive problems causing vomit and diarrhea are more frequent in the Yorki than other toy breeds. Occasionally it is recommended to provide it with hard croquettes to keep the teeth healthy. Veterinarians have detected kidney stones as well as cryptorchidism. The Yorkie usually lives more than ten years.
