Manchester Terrier


Also known as the "Rat Terrier", the Manchester Terrier is possibly the fastest and best known breed of dog to hunt mice and vermin. This breed is known to kill dozens of rats within single minutes. The Manchester Terrier was developed hundreds of years ago by crossing the Whippet and Black and Tan Terrier bloodlines. Today, this is a popular breed within the USA.


Standard Manchester Terrier : This is a small breed dog with males and females measuring 15-16 inches in height and weighing up to 18 pounds in weight. Toy Manchester Terrier : This is an even smaller version of the Manchester Terrier that is bred down selectively and generally both males and females weigh 6-8 pounds in weight and measure 10-12 inches in height. This small breed dog has a small wedge shaped head that directly forms into a narrow muzzle and a scissor bite. Their two large ears are thin triangles and stand tall and firm on the top of their head - unless left naturally, at which the triangles fold 1/4 of the way up and fold directly facing forward. Built small, slender and muscular, this breed has a rectangular shape and four straight, thin legs. Their two small eyes are almond in shape and available in a dark brown to black in color. This breed has a medium length tail that is thicker at the base and tapers down to a point at the end. Their single layer, short hair coat is only available in black and tan with their distinct markings.


The Manchester Terrier is not a breed for everybody. This breed is not recommended for homes with small pets, small children and must be within a home that is very active.

If this breed does not receive enough mental and physical exercise daily, it will result in negative and destructive behavior. The Manchester Terrier has a natural want and drive to learn from his or her human owner and truly wants to please them; this breed has to have a daily task or job at hand to remain happy. Please note that this breed is not suited for apartment life.

Special Notes

Please note that this breed is extremely fast and remains a natural hunter to small animals; due to this, the Manchester Terrier requires a properly fenced in yard to remain safe within while spending time outdoors. Please fully research yourself about this breed prior to adding one to your home to ensure you are able to make a life long commitment both physically and financially. This breed is prone to glaucoma and sun sensitivity. All dogs originate from wolves (Canis Lupus). Each breed of dog was originally created by mixing different breeds together in an effort to bring forth certain characteristics. Once a breeder has created acceptable “breed characteristics” within their bloodline and these “breed characteristics” have shown to be reliably reproduced in the offspring for three (3) generations, the bloodline may be upgraded from the category of “foundation stock” to “pure-bred”. The same “pure-bred” breed standards vary from different continents, countries, territories, regions, breed clubs, and canine pure-breed registries depending on the goals of their breeders. Dog DNA testing companies can have accurate results for a specific bloodline of a small colony of dogs. However, there are tens of thousands of different bloodlines in the world which have not yet been tested for marker baseline results by Dog DNA testing companies as of 2017. For this reason Dog DNA testing companies do not guarantee the 100% accuracy of their breed lineage results and will also show different marker results for the same pure-bred breed in different continents, countries, territories, regions, breed clubs, and canine pure-breed registries depending on the goals of their breeders.
