Overview

The Rat Terrier came about during the late 1800s with the necessity to rid farms and homes of pets such as rats, mice, rabbits, moles and such. Theodore Roosevelt, himself, was an owner of several of this breed he used to hunt; presently, however, the majority of them are companions. Members of this breed are easily trained, playful, protectors of the home, and thrive off affection. These qualities make them wonderful additions to any home whether the owner is hunter or homemaker, young or old.

This breed does form close bonds with other animals it is introduced to at a young age; the exception to this fraternity is rodent or vermin like creatures. Rat Terriers are reserved around strangers and will bark to alert the owner of any person or animal unknown. They are long lived little dogs; it is not unheard of for them to reach 18 years.

Rat Terrier Breed Description

The Rat Terrier is considered a small dog and comes in two sized. The standard size is from 13-18 inches at the shoulders, while the Miniature is 10-13 inches. There are no weight requirements documented by the AKC, however, the dog should appear athletic, with smooth lean muscle that lies flat to the body (not bulky).

Playful, happy, friendly and athletic are amongst the traits that make Rat Terriers fine family dogs. It is common for them to be reserved around strangers at first and they consider themselves guardians of the house; they will not hesitate to bark at a strange human or pet that passes too closely. They see dogs, livestock, even cats they grew up with as part of their "pack" and may bond very closely with them. Rats, mice, hamsters, ferrets, rabbits and other rodent like pets are not advised to be housed with this breed due to their hunting instincts.

Overall, this breed can be considered low to average maintenance. They are shedders, but a weekly brushing can help to reduce this and keep all of the hair from ending up on the floor. The typical doggie regimen of weekly teeth brushing and bimonthly nail trimming and ear cleaning should keep them in fine shape; bathe as necessary.

Members of this breed have medium energy requirements and their favorite way to relieve them is to do activities with the owner; whether it be a daily run, walk, hike, yard time, hunting or even training - this dog is down for adventure.

The easiest to train of all Terriers, the Rat Terrier is not only intelligent and eager to please but also intuitive and sensitive to its owner. They thrive off praise and petting, and of course, treats and do not do well with tones and body language that are harsh. Not to mention, agility and obedience training are excellent ways to bond with and exercise your Rat Terrier.

Rat Terrier Breed History

This breed is quite the hodgepodge of previous terriers that came about in America during the late 1800s that were brought to America by, mostly English, immigrants. Among those thought to be the forerunners of this breed are: Fox Terriers (Smooth and Toy varieties), White Terrier, Manchester Terrier while these prototypes later mixed with Beagles for hunting and Whippets, Greyhounds and other non-Terriers to increase their speed. During the early 1900s the need was high for a dog that could hunt down the Jackrabbits ruining crops; this called for an athletic and swift worker. Theodore Roosevelt often hunted with Rat Terriers. The UKC has recognized this breed since 1999 and, although allowed to compete in companion and earthdog events, the breed was not officially recognized by the AKC until 2013.

Rat Terrier Appearance

The Rat Terrier was bred from many other Terrier and non-Terrier breeds, therefore, they are often mistaken for Chihuahuas, Jack Russells, and other Terriers. This dog was bred to hunt and course rodents and other pests as well as small game. The overall appearance of the Rat Terrier is a well-balanced and speedy little dog; they are compact and strong with the flat muscles blending into the body.

Their coat is short, dense and looks somewhat smooth and shiny and, while it comes in a multitude of colors, the only acceptable solid coat is white. The chest is somewhat wide and reaches the elbows while the back is straight. He has a wedge shaped head that tapers towards the large, bat-like ears; the ears can also frequently be button or semi-erect. The eyes are small, widely set and a shade that varies from darkest brown to hazel (depending on coat color); not to mention they always display an inquisitive and alert expression. The shoulders are flat and front legs are straight and parallel, ending in compact, well-padded feet; the lean muscled hind legs are well balanced with the front, save for the slightly smaller feet. Rat Terriers have a either a naturally bobbed tail or one that is help up and curved; owners can also choose to have the tail docked.

Rat Terrier Coloring

Members of this breed come in a myriad of colors in combination with white. In fact, 18 variations of this breed's coat are considered standard by the AKC.

To add to the confusion, there are also a plethora or markings that may or may not be present.

Badger markings, irish marked, spotted or patched, tan points, or sable white markings are also common. Refer to the images for examples of all types.

Rat Terrier Temperament

Originally, this breed came about from the need to keep away pests such as rodents, vermin, raccoons, etc. Presently the Rat Terriers is, first and foremost, an owner's companion whether they are hunter or homemaker, old or young. Friendly, loveable and inquisitive they are ready for adventure and are happiest when accompanying you on any activity. This breed is great with kids and pets if socialized at a young age, the only exception being rodent like pets, which may activate their hunting instincts. They are often said to be so friendly with other dogs that they may bond more with the other pet in the household than you.

Eager to please, these dogs will excel at obedience and agility training. In fact, they are referred to as the "most trainable of terriers." This training is also a great way to burn off some of your pet's energy as well as socialize them. They are dedicated workers and intelligent enough to learn quickly. Rat Terriers are also said to be intuitive and sensitive, so harsh words or tones are not necessary to capture their attention; instead, they thrive on praise and attention.

Rat Terrier and Children

Playful, happy, friendly and athletic are amongst the traits that make Rat Terriers fine family dogs. Members of this breed are eager to please and love hanging out with the family, in addition, they are not very large and can be trusted to spend time alone with kids if trained at the appropriate age.

Rat Terrier and Other Pets

Most owners would agree that their Rat Terrier get along very well with dogs and large farm animals. Cats in the household should also not be a problem as long as your pet is socialized at an appropriate age. However, small rodent like pets will entice their natural inclination to hunt and chase, so owners with these pets should consider another breed. This also goes for wild outdoor rodents and vermin; your Rat Terrier should be exercised in a fenced area or kept on leash at all times. They are not naturally aggressive but will defend their territory if aggressed upon.

Rat Terrier and Strangers

These dogs are considered friendly and playful once they become familiar with the person, however, it is common for them to be reserved around strangers at first. Those looking for an alert and dedicated watchdog will find the Rat Terrier a fine choice. They consider themselves the guardians of the house and yard and will alert the owner to strangers by barking.
