Rat Terriers are affectionate, energetic and easy to train. The American Kennel Club recognized the breed in 1999, according to Dog Pages. Rat Terriers are considered a good family pet and have a life span of 12 to 18 years.
Dog Pages indicates that Rat Terriers were originally bred for ranches or farms to eliminate rats and other vermin.
According to the Rat Terrier Club of America, there are no official toy Rat Terriers. They may be Mini (miniature, 10 to 13 inches) or standard (13 to 19 inches), according to Dog Pages. They can weigh 10 to 25 pounds.
Mini Rat Terriers come in a variety of colors and combinations including chocolate, blue, lemon, orange, sable, rust and red, according to Dog Pages.
Dog Pages indicates that the Rat Terrier is well-behaved and protective of its family. The Rat Terrier Club adds that they are good with children when raised around them.
The Rat Terrier requires plenty of exercise, according to Dog Pages. Once- or twice-monthly baths and brushing once or twice weekly is sufficient, since they do not shed heavily.
Common health problems among Rat Terriers include allergies, luxating patella and Demodex mange according to the Rat Terrier Club.
