Exercise needs

Some Rat Terriers can get sufficient exercise for their needs through indoor playtime, but most will thrive with daily walks and a bit of tennis-ball-chasing and other play in a fenced enclosure. They tend to do well with other dogs their size or larger. Early socialization is a must, and puppy training classes are recommended. [1]

Grooming

The Rat Terrier's short, dense coat requires very little care to remain in good condition. A weekly once-over with a soft brush or hound glove will keep his coat healthy and glossy. A bath every month or so will likely be enough, depending on the dog's lifestyle. [1]

Health issues to budget for

Rat Terriers are generally very healthy dogs, and responsible breeders screen their stock for health conditions such as hip dysplasia, patellar luxation (loose kneecaps), Legg-Calve-Perthes disease, and cardiac and eye disorders. A conscientious breeder does genetic testing of all breeding stock with the aim of reducing the incidence of and ultimately eliminating health problems. [1]

AKC-recommended health tests for breeding dogs: Patella Evaluation, Hip Evaluation, Cardiac Exam, Primary Lens Luxation (PLL) - DNA Test. [1]
