Jack Russell Terrier

The Cocker Jack is a small to average sized dog that is the result of crossing a Jack Russell Terrier and a Cocker Spaniel. This new breed is friendly and active, a perfect blend of the two parent dogs. The boldness of the Jack Russell Terrier is tempered by the reservedness and softer Cocker Spaniel characteristics. The Cocker Jack is ideal for a family, although supervision is needed with younger toddlers who can sometimes play a bit rough and may unintentionally hurt your small dog. These dogs are loyal and affectionate, devoted to their human family. They can be a bit reserved around strangers, but when they warm to them, they become welcoming and friendly.

Cocker Jack Breed History

The Cocker Jack doesn’t have a lot of data about its entry into the hybrid breed history books so the easiest way to analyse your Cocker Jack's likely characteristics is to look at the past of the parent breeds. The Jack Russell is a proud and plucky little dog. They were originally bred to hunt foxes who had gone underground during a hunt. The breed originated in Devon, England in the mid-1800s. The Reverend Jack Russell who founded the breed preferred a longer legged terrier that could keep up with the hounds so he created a longer legged type known as the Parsons Russell Terrier, of which the Jack Russell Terrier is a smaller version. Looking at the Cocker Spaniel's history, their history is entwined in hunting as is the Jack's. The name spaniel means Spanish dog and it is believed that they began in Spain. In 1881 the American Spaniel Club was formed and included many types of Spaniels. Over time, the breeders split into separate organisations as differences among the spaniels were defined. It took many years of work before the American Kennel Club finally recognised the American Cocker Spaniel as a distinct breed. The Cocker Spaniel became a favorite in the show ring and breeders moved away from breeding them for hunting and more towards traits that would win in the show ring. The Cocker Spaniel has a sweet temperament and is affectionate and loves his family. They are known to have a sensitive nature, which means they need gentle and kind handling to bring out their best. The Cocker Jack is therefore blessed by two sets of genes producing an active, affectionate and totally lovable dog.

Cocker Jack Breed Appearance

The Cocker Jack dog can vary considerably in appearance depending on what parent dog it takes after most. They can have the typical Spaniel look with the longer silky hair, the floppy often feathered ears, and the fluffy tail. Or they can take after the Jack Russell Terrier and have the short smooth hair, the smooth folded ears, and the straight pointed tail. Whichever it may be, they will have the most appealing face with large oval eyes with dark rims. The head is rounded in shape, with a long muzzle that is in proportion to the head. A black nose with wide set nostrils and a happy smile defines the face. The body is sturdy and strong, with short study legs and small rounded paws.

Cocker Jack Breed Maintenance

The Cocker Jack dog is a low maintenance dog having a coat that is easy to keep clean and looking good. Brushing twice a week with a firm bristle brush will remove any loose hair and bathing only when needed will keep the coat in good condition. Remember to use a special dog shampoo when bathing, as human shampoos are too strong and may cause allergies. Other maintenance tasks include keeping inside the ears clean and checking regularly to see there is no build up in debris or infection. If there is you will notice an unpleasant smell coming from the ear and your dog may paw at his ears and whine. A quick trip to the veterinarian will help to clear the infection up. Clean your Cocker Jack's teeth regularly. You need to start this practise when your dog is young to get them used to it. At first, make the brushing short in time and reward your dog with hugs and lots of praise for their efforts. Soon your dog will come to love their regularly grooming sessions and see it as a way to get more attention from you.

Cocker Jack Temperament

Cute, fun, affectionate and happy comes to mind when discussing the Cocker Jack. They are active little dogs, but will fill your lap the moment you sit down. The Cocker Jack does well at training, but it may just take a lot longer and require more of your patience as they can have a slight stubborn streak. Short sessions at first will help their focus, and try and make it fun for them with lavish praise and the odd treat. This dog may be slightly snappy with young toddlers as they don’t react well to tail pulling or ear chewing, but to mitigate the risk have the puppy grow up with the children and teach both dog and kids to respect each other. The Cocker Jack will love to play, and enjoys a bit of space to explore, therefore a well fenced yard is ideal. Some dogs tend to dig everywhere so be aware of this early on and try distraction to keep them from developing that habit. They are best with a strong but kind owner who establishes themselves as the pack leader. All things considered, the Cocker Jack is a lovable small dog who will win your heart and be a devoted little companion.

Cocker Jack Activity Requirements

Depending on how much your Cocker Jack dog takes after its parent breed, the activity level can vary quite a lot. Some dogs can be full on like the Jack Russell, whereas others can be more mellow and laid back like the Cocker Spaniel. But whatever the case, your Cocker Jack will need a daily walk to keep them fit, and will enjoy the freedom to play and socialise with other dogs at the dog beach or park. At home, a fenced yard is ideal for these dogs.  They can live in an apartment if they get enough exercise and mental stimulation to keep them happy. The Cocker Jack is fine in either hot weather where swimming will help keep them cool, or in colder climates where they may need a dog coat when out walking. They should have approximately an hour walk daily to keep them agile and fit.

Very sweet dog, but scared of strangers which resulted after she was attacked by a much bigger dog when just a puppy. Fiercely protective of the family and very smart when it comes to getting food on the counter.

She is still a puppy, but boy does she keep us on our toes. One thing that I am not fond of is that she will always chew on our shoes, although we bought her, her own toys...Not sure how to train her not to do that, if you have any advise, please. Overall, she is a very friendly and lovable pup, my little fur baby...

Best dog ever. Very healthy and affectionate. He was a great puppy, house trained very easily and did not chew on much but his toys. He will be a lap dog until the end and at fifteen his only health problem is arthritis, I believe due to lifetime of very hard play, running, pouncing, chasing and retrieving. Everyone has thought he was a black lab puppy throughout his long life.
