Originally, the terrier was a working dog. It served a regal fox hunting dog.

The dog has many distinct features. Size really counts for a terrier of this stature. Hunting foxes is a tricky profession. The dog should be able to hunt both above and below ground. It is their unique size that allows them to get the job done. When a Parson Russell Terrier has reached his mature height, he is only 14 inches high. Females reach approximately 13 inches. Either may weigh between 14 to 18 pounds.

The terrier is a very active dog with loads of spirit, who wishes only to please his master and requires lots of regular exercise. A proper breed has V shaped ears that usually point toward the eye. He is keen and alert at all times. This is what makes the Parson Russell Terrier such a great hunting dog.

A muscular body is strong, straight, and adequately level as the dog is in motion, which helps the terrier maintain it's agility. Also, the terrier must have a flexible back for making sharp turns. Fox holes are winding and take on many different levels, so maneuverability is a must. Their heads are well proportioned to the body to provide balance.

The Parson Russell Terrier is white in color with brown, or black markings. The beautiful, dark, almond shaped eyes are set evenly apart. Its nose is black.

As a show dog, the breed is recognized as highly intelligent. Though they are easily trained, they must not be allowed to take control. They must be shown that the pack leader is boss. Since chasing and exploring is their nature, Parsons should not be left alone with other small animals. Their energy is endless, willful, and determined. Parsons can also climb fences and jump as high as five feet. This type of terrier does exhibit some shyness, so it is a must to socialize.

The Parson Russell Terrier does not emit many health problems. A working dog however is prone to joint problems, dislocated kneecaps, and eye irritation from ripping through brushes and loose ground.
