Irish Jack Russell vs Brussels Griffon - Breed Comparison

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.

The Brussels Griffon is one of the three different types of Griffons. There is the Belgian, the Petit, and the Brussels Griffon. “Griffon” means wiry and the Brussels Griffon lives up to that moniker. The Brussels Griffon’s coat is longer than that of the Belgian Griffon and the Petit Brabanon (Griffon) has a smooth, short coat. The breed is probably originally developed by crossing Belgian street dogs with the Affenpinsher as early in the 1800’s. They were favored by the cabbies in Brussels as guard dogs. They were also bred to hunt rats. Sometime toward the end of the 19th century, the Griffon was again crossed this time with a pug. This accounts for the type of head that the Brussels Griffon has, namely a brachycephalic head. It also accounts for the smooth coat of the Petit Griffon. The modern-day Griffon may also have been crossed at some time with one or more of these breeds: the English Toy Spaniel, the Irish Terrier and the Yorkshire Terrier.

By 1880, the breed was recognized and appeared in the Brussels Exhibition of 1880. They were also found in paintings of the same era by the Flemish painter, Van Eyck. In the beginning of the 20th century, the breed was extremely popular with the nobility in Belgium. As with so many other breeds, the number of Brussels Griffon was greatly reduced during the First World War. It did not take them long however to make a comeback after the war. Their popularity then spread around the globe.

The European FCI considers the Brussels Griffon, the Belgian Griffon and the Petit Brabancon (Griffon) to be three separate breeds with no interbreeding among them. They are shown as three separate breeds in Europe, with the difference between the Belgian and Brussels being the accepted colors. The Brussels is only red in color while the Belgium Griffon can be in all other colors. In the United States the three types of Griffons are considered one breed with three varieties. Only the Brussels Griffon is recognized by the AKC. The difference in coat and color make for the different varieties in the U.S.

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.

He looks much like your regular Jack Russell but he has shorter legs, and where the regular Jack Russell has an essentially white coat with orange-tan patches, the Irish Jack Russell can be solid tan or other color variations such as red, brindle, black and tan.

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. These are dogs which can become possessive of their owner and they can become quite aggressive when protecting their family. He is a highly trainable dog but it is important to have him trained as he tends to be aggressive with other dogs.

He is busy, active, happy and inquisitive and will require regular exercise to prevent him becoming restless and destructive. He has been a working terrier and he always wants to be busy.

All three types of Griffons are toy size dogs with short, thick bodies and distinctive brachycephalic heads. Regardless of coat color their muzzles and whiskers are black, and they have large eyes, also black, a mustache and beard. They have black eyelashes and a nose that is very black. All this is set against their red, beige, black or black and tan coat. Their forehead is dome shaped and the muzzle is short. The breed has small ears that are high up on the dog’s head. The ears might be cropped in the United States but would not be in Europe. The lower jaw is prominent and the jaw itself is undershot. They have black toenails and pads, with strong and muscular hind legs. The Griffon has a docked, high set tail in the U.S. and a full tail in Europe and all of the United Kingdom.

The rough coated types have a dense and wiry coat and the standard encourages the hardest possible wire coat. Their heads are also wiry and long around the chin, cheeks, nose and eyes. They should be hand-stripped and never left ungroomed. The coat can matt if not taken care of adequately. One of the most important features of the Brussels Griffon is its human like face or monkey like appearance.

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.

Characteristics

The Brussels Griffon is sociable, alert and very intelligent. She is very energetic, playful and loving. They bond deeply with their family. Housebreaking might be a challenge as it is with all toy/small breeds. They are incredibly lonely and restless when their people are not around them. They have great personalities, terrier like characteristics, and deep loyalty to their humans. They are great companions and love children. Just remember how small they are. They are susceptible to Little Dog Syndrome if the human does not establish themselves as the alpha right away.

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 Brussels Griffon is susceptible to many of the diseases and genetic conditions that many other toy or small dogs have. Flat-faced breeds like the Griffon also suffer from difficulty with breathing under certain weather conditions and they are known to snore. They should not be kept in hot, sunny, humid climates for this reason. They may also display patella luxation (slipping kneecaps) and hip dysplasia. Lastly, they are susceptible to ear infections. Dams are often in need of cesarean sections to deliver their litters. They have very serious health issues due to the head shape and flat face. These might include eye and respiratory issues and syringomyelia – a deadly neurological disease. They are susceptible to epilepsy, dental issues and eye lash issues.

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.

Feeding

The Brussels Griffon can choke easily so take care with the size of kibble you feed them. They need about one fourth to one half of a cup of high quality dry food that is designed for small or toy dogs. Divide this amount into two or three small meals per day. Puppies should be fed more often than adults but never feed just one large meal per day. Be careful that your Brussels Griffon does not become obese.

Health issues

The Brussels Griffon, regardless of type has some very serious health issues due to the shape of their heads.

Syringomyelia – extremely painful and fatal neurological disease.

Brachycephalic Syndrome – This can cause all the respiratory issues as well as eye issues such as cataracts and corneal ulcers.

Epilepsy - Seizures

Dental Disease – gum disease

Puppy Mortality – one of every four Brussels Griffon pupped die at birth.

Exercise and games

This is a very playful and energetic breed that needs at least some exercise every day. They love to play with their family. They are smart and easy to train. They love agility, obedience, barn hunt and tracking activities. You can just as effectively play with and exercise your Brussels inside as well as out.
