Irish Jack Russell vs Dunker - Breed Comparison | MyDogBreeds

Originating in the United States of America, the Irish Jack Russell, also known as Short Jack Russells, was bred to bring about a calmer temperament and to also have a dog with shorter legs.

Always a working dog, breeders of the Irish Jack Russell wanted to create a dog with less of a hunting instinct in him and have a dog which would be more companionable.

These Irish Jack Russells look much like your regular Jack Russell but are more of a companion dog than a hunting dog. The Irish Jack Russell doesn’t adhere to any existing Jack Russell breed standard and isn't really recognized at major dog clubs and kennels. The truth of the whole matter is that there are different kinds of Jack Russells and different names given to them to differentiate between the taller Jack Russell and the short legged one. The shorter Jack Russell Terriers are known by many names such as Irish Jack Russell and Shorty Jack Russells.

Known as the Norwegian Hound, the Dunker hails from Norway. Bred and named after breeder Wilhelm Dunker to be a robust scenthound, Norwegian Scenthounds were crossed with a Russian Harlequin Hound because this particular dog was an excellent scent trailer and it could stand up to the freezing conditions of Norway.

The Dunker become popular in the mid-19th century in other Scandinavian countries. Hunters liked its intelligence, its robustness and its speed and strength. In 1902 a club was founded for the breed and in the same year the Norwegian Kennel Club recognized the Dunker.

The Dunker started dying out after the war, and in the late 1980s breeders of the Dunker petitioned to allow them to cross the remaining Dunkers with scenthounds. Today the dog is known in Norway but is uncommon outside Scandinavia.

Irish Jack Russells are small dogs standing at roughly 18 to 35cm and weighing in the region of 5 to 8kg for both males and females.

The coat can be short or fairly long and coarse. The Irish Jack Russell is a sturdy, compact dog with a flat skull, brown eyes and ears which are semi-erect, semi-floppy. He has a bright, alert, intelligent look on his face. The tail is set fairly high and has always been docked but these days it is inclined to be left long, taking away from the dog’s nice compact look.

Temperament:

The Irish Jack Russell is perhaps more placid than the regular Jack Russell and that is why he can adapt to life in the city or in the country. They’re intelligent dogs and therefore easy to train and have socialized.

Even though he is a small dog, training and socialization is important as he is a feisty, stubborn, know-it-all little dog.

The Irish Jack Russell is a self-confident, energetic dog who will like nothing more than to be involved with everything you’re doing. The busier he is the better, and because he has strong hunting instincts you may find him digging in your garden for rats.

Have him trained and socialized if you want to avoid certain problems with him and remember to exercise him and provide him with the attention he craves.

He is a social dog and will pine away if you just leave him to get by on his own. Make sure that he becomes every bit as part of your family as everyone else and he promises to make you a loyal, devoted companion.

The Dunker is such a good tempered dog and he will be happy to settle in the city or the countryside with his owner.

When you look at his history, he is a hunting dog, used for hunting rabbits. Being an active breed, he is better suited to living in a home where there is at least a fair sized garden.

He isn’t a high maintenance dog either, so no special attention to grooming is required. Being a fairly healthy breed, he isn’t likely to develop any serious health issues too. This low-maintenance, undemanding Norwegian Hound makes a splendid pet.

Your Irish Jack Russell is a dog that doesn’t battle with too many health issues, but nonetheless you still need to watch out for common health problems.

Jack Russell terriers are generally a healthy breed that can live up to 14 years of age, but still every dog is prone to the more common dog problems such as hip dysplasia, bloat, ear infections and dental disease among others.

If your Irish Jack Russell is in pain, he is lethargic and sick, don’t delay – take him to the vet right away.

The Dunker dog can live to reach a ripe age of 12 to 15 years. There are some health issues he may face -

Partial or Complete Loss of Hearing:

Partial or complete hearing loss can come about because of dirt or wax build-up in the ear canals. It can be because of an untreated ear infection, an injury or even old age.

Your veterinarian can examine your dog’s ear canal. Certain dog breeds such as the Dunker and others are more predisposed to deafness and you’ll find your dog responding slowly to your voice or he may be totally startled when woken.

Your vet will determine the type of treatment for your dog if an ear infection for instance is suspected. Treatment in this case may involve cleaning wax out of the ears or getting rid of overgrown ear hair.

Hip Dysplasia:

Hip dysplasia is an inherited condition with your dog where bone rubs against other bone. Your Dunker dog will be in pain and his movement could be limited and he may even become lame. Get your pet to the vet because there are a number of treatment options.

Eye Problems:

Take a look at your pet’s eyes so that you’re aware of cloudiness, inflammation, discharge, a change in eye color or red eyelid lining. Take him to the vet if you suspect something serious, but in the meantime you can also gently wipe over your pet’s eyes to remove any discharge.

If you do need to bath your pet, make sure to protect his eyes before applying any lotion.

Grooming:

The Irish Jack Russell is an average shedder with his short or longish coat which is easy to groom, requiring a brush once or twice a week. His nails grow quickly too and they can get caught on something and cause him damage. Trim your pet’s nails to prevent this.

Diet:

Feed your Irish Jack Russell good quality dog food each day. If you feed him commercially manufactured dog food, be certain to check the feeding instructions on the packaging.

He is a small dog, and overfeeding can be just as bad as under-feeding. It’s never a good idea to just go on and on feeding your pet dry or wet kibble day after day. Add in some cooked chicken, rice, pasta and vegetables as a treat and to also provide some variety for him.

Also a little bit of raw meat occasionally can do him the world of good and you’ll see the appreciation in his bright eyes and wagging tail.

Exercise:

The Dunker is a dog with stamina and energy and he will need a walk every day as well as some other forms of vigorous exercise. The idea is to involve a dog like this in all your activities, whether you go running, swimming or cycling.

Grooming:

The Dunker isn’t going to require you to spend a lot of money on maintenance for him. A good brush-down twice a week will be adequate as he is a fairly heavy shedder and brushing him will get rid of all those loose hairs. It is also time to check him over for fleas and ticks too.

Other grooming aspects to check will include nail trimming, checking the inside of the dog’s ears for excess wax build-up and dirt.

Dental care is of major concern because teeth left unattended can result in mouth bacteria. This bacteria enters the blood stream and results in systemic infection. Sometimes the bad teeth can be so painful that a dog no longer wants to eat.

It is imperative to brush your pet’s teeth at least 2 or 3 times a week with a special dog toothbrush and toothpaste.
