Jack Russell Terrier
They are active dogs, and are easily trained. A hardy breed that isn’t prone to many ailments, they do well as an indoor pet as well as an outdoor pet. They also do well around children, elderly people, and even single people. They don't need much attention.
They also have a beautiful coat of white, with black and brown markings. Quite possibly the perfect family pet, if you don’t mind a shedding dog.
