Cav-A-Jack Breed History

While there is not much information on the Cav-a-jack breed itself, one can still learn much about the breed by studying the parent breeds. The early beginnings of the feisty Jack Russell Terrier involved the hunt. Perfectly suited to the job, the Jack Russell Terrier was a courageous, energetic breed that loved to work. A small game hunter, his agile form and tenacious spirit made him a desired partner in the forest and on the field. He was recognized by the American Kennel Club after the diligent work of fanciers over the years; his name was officially changed to the Parson Russell Terrier in 2003. The Cavalier King Charles Spaniel was a companion dog right from the start. A nobleman and royal gentry's choice, he graced the courts with his presence and was highly favored. Kings Charles I and II eventually gave him their name, so taken were they with the breed. Brought to the United States in the mid 1500s, the American Kennel Club added them to their roster in 1995.

Cav-A-Jack Breed Appearance

The parent breeds of the Cav-a-Jack vary greatly in appearance. The Cavalier King Charles Spaniel generally has a silky medium-length coat and may have a wavy texture.

His muzzle will be small and his nose most often black. His eyes will sparkle with mischief and be light to dark brown in color. He will be sturdy in build and quite likely will have a spunky, purposeful gait.

Cav-A-Jack Breed Maintenance

The Cav-a-Jack has moderate grooming requirements. He will need weekly brushing with a pin brush or slicker brush depending on the thickness and consistency of the coat. When he sheds, brushing a few times a week should be enough to remove the loose fur. Depending on the length of his ears, a weekly check for dirt and moisture may be required, especially if your Cav-a-Jack spends a lot of time in the dirt and brush. Maintaining his teeth is important. Brush them several times a week in order to avoid costly dental expense. His nails should be checked and trimmed bi-monthly. When your Cav-a-Jack is young, get him used the grooming routine. It can be a nice bonding time between pet and owner.

Cav-A-Jack Temperament

The Cav-a-Jack is a lively, spirited little dog. The Jack Russell Terrier parent is a highly intelligent and inquisitive dog. The Cavalier King Charles Spaniel balances out the feisty personality by adding a touch of calmness and loads of affection. Your Cav-a-Jack will love his family dearly and prove to be a very adoring family member. He will want to be with the family; do not leave him unattended outside no matter how secure you think your fence may be. He is able to spring over a fence or even dig under it in order to get to what he wants. He may or may not get along with cats since they could appear to be prey and fun to chase. Though an affectionate hybrid, the Cav-a-Jack does have an independent side and will need firm, consistent guidance. Some owners have found the Cav-a-Jack tougher to toilet train then other hybrids but with perseverance your Cav-a-Jack will get it right.

Cav-A-Jack Activity Requirements

The Cavalier King Charles Spaniel parent is the type of dog that can be happy sitting on his owner’s lap for long periods throughout the day while the Jack Russell Terrier is a bundle of energy. Capable of scaling a fence if he thinks there is action he should be a part of on the other side, this side of the equation means the energy level of your hybrid may be fairly high. Allow him an hour a day of interaction with you in the form of play, brisk walks, and obedience classes. Your Cav-a-Jack may excel  at activities like field trials or agility so don't be afraid to let him give it a try. He can adjust to apartment living but will be happiest if there is a dog park within close proximity that can be visited every day. A home with a fenced yard is ideal as long as supervision is always maintained.
