The Jack Russell is a happy, bold, energetic dog; they are extremely loyal, intelligent, and assertive. Their greatest attribute is their working ability, closely followed by their excellent qualities as a companion. Unlike some modern breeds, Jack Russells have one type, hunting. Hunting ability is bred into them. It is their nature. The unique personality of this feisty terrier is rapidly gaining popularity, but they are not a dog for everyone, especially first time dog owners. While adaptable to to a variety of environments, they are first and foremost bred to hunt.

These dogs come in three different coat types; smooth (recessive), broken (intermediate), and rough (coarse, longer straight hair, dominant over smooth). All coats shed, smooth coats shed the most. They are adaptable to most climates, and usually handle the cold fine, although some dogs will need a dog blanket or sweater if under 40 deg. Fahrenheit. The color of the coat must be at least 51% white, or all white. Black and/or tan markings are allowed. Height can be between 10" and 15", with a proportionate body length.

For showing purposes, terriers are classified in two groups, 10" to 12 1/2", and over 12 1/2" and up to 15". Dogs should appear compact and balanced, always in solid, hard condition. Jack Russells have a short, upright tail, about 4" long. The tail is cropped shortly after birth, and front dewclaws are removed.

Jack Russell Terriers are very energetic dogs, with a big need for regular exercise. They are working dogs, and need to have a job, whether it be keeping your yard free of rodents (digging is normal and common, since they are bred to dig after quarry), chasing a ball, or going for a run or long walk with it's owner. Sitting on the couch peacefully all day is not in a Jack Russell's agenda. They require more of a time commitment than some breeds. Because they are small, they seem ideal for living in an apartment.

Will a Jack Russell be happy in an apartment situation?

Given the exercise requirements of the Jack Russell, a home with a large, fenced yard is more appropriate. They do not take well to inactive, sedentary lifestyles. However, if you are at home during the day or are able to provide regular exercise, it may work. They need a 5-6 foot high fence, since they are known to jump, climb, and even dig under fences.

Will a Jack Russell Terrier cohabititate with my cat/small pet/young child/horse?

Cats and other small pets (rodents) will usually not work with a Jack Russell because these dogs are first and foremost hunting dogs. They see the cat or hamster/rat/guinea pig as prey (quarry). This is not true for all Jack Russells, and if brought into the household as a pup, most could be trained to live with a cat. Many Jack Russell owners are horse people. Jack Russells are not herding dogs, so the horse isn't of interest to them. Children under the age of six can be a problem, unless the child is taught how to properly handle the terrier. Having the natural assertive terrier characteristics, however, the Jack Russell will not put up with even unintended abusive behavior from a child. This should be carefully considered, particularly with children under six.

Are Jack Russell Terriers dog aggressive?

They can be very aggressive with other dogs (not just other terriers), and in certain cases, more than two terriers shouldn't be kept together unattended. It is very important that prospective Jack Russell owners understand this sometimes harsh part of the terrier's nature.
