In the United Kingdom, it is the recognised show variety of the Jack Russell Terrier, after the breed split into two distinct varieties, with the Parson Russell Terrier being slightly taller and narrower than the Jack Russell. Parson Terriers are tough, feisty little dogs that have a smooth or broken coat (a mixture of rough and smooth) which is predominantly white with black, tan or tricolour markings. This is a breed that is always alert and ready for action. Out on walks, they will be constantly inquisitive, investigating their surroundings and potentially disappearing down rabbit holes and always ready to run and chase. They are confident little dogs, who love human contact, and will enjoy being at the centre of everything. As a busy dog, plenty of exercise is recommended, as well as lots of playtime to prevent them from getting bored. Parson Russells make good family pets, especially if they have been well socialised from a young age, although may lack tolerance around younger or overly exuberant children. Again, with good early contact and experiences, they will be fine with other dogs too. Their high prey drive makes them generally unsuitable to be housed with cats or other small household pets. These are confident, exuberant and affectionate dogs, which makes them an excellent and fun addition to an active household.
