Irish Jack Russell vs Bull Terrier Miniature - 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.

Less well known than the Bull Terrier, the Miniature Bull Terrier which actually follows the same breed standard, has a height of 35cm. The Bull Terrier and Miniature are classified as the same breed. The weight of the smaller Miniature is only about 15kg.

It was in the early 1800s that the Miniature Bull Terrier was developed, descending from the English Bulldog as well as the White English Terrier which is now extinct. This blend produced the Bull and Terrier, which was later shortened to the Bull Terrier. They came in a number of colors such as pure white, white and tan as well as white-and-black-patched or tri-colored.

Breed fanciers wanted a compact dog which looked much the same as the larger Bull Terrier. It was in 1938 that Colonel Glyn founded the Miniature Bull Terrier Club in England and the Miniature Bull Terrier Club of America was formed in 1966.

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.

Miniature Bull Terriers, just like the regular Bull Terriers have short, glossy coats and these coats can be white, tan, brindle or tri-color such as black, tan and white. This is a muscular little dog, with the same very distinctive egg-shaped head and small, closely-set dark eyes and erect ears. The medium length tail is carried horizontally.

The Miniature Bull Terrier isn’t particularly good with small children, but he still makes a good companion for people, whether he lives in the city or the country. In fact, this smaller breed Bull Terrier makes a great pet for people with smaller spaces, and like the Bull Terrier, he is a loving, devoted pet. He has an entertaining personality, is playful and energetic, making him a good watch dog.

However, even though he is small, he is always more than ready to take on any larger pets and therefore isn’t considered the greatest pet to have if you have other animals in the house. However, with excellent training and socialization, this handicap can be overcome.

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 attractive Miniature Bull Terrier is just a small version of the regular Bull Terrier, and many people are drawn to them because they have all the spunk of the larger breed but are easier to manage. He is such an entertaining little dog and guarantees to make an excellent family companion. He is just longing to be involved in every family activity happening around him.

He becomes attached to his human family, but this deep bond between him and his family can lead to separation anxiety. Never leave him alone day after day in the backyard. You wouldn’t to that to one of your children, and he is a family member, albeit a 4-legged one.

Just like the standard Bull Terrier, the Miniature Bull Terrier is going to need firm training from a young age. Then he becomes an exceptional pet as he understand the boundaries in your particular home.

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 Miniature Bull Terrier can live to be 10 to 12 years of age. Their most serious health issue is blindness which is caused by lens dislocation, showing up more or less after 3 years of age. With the white dogs, other breed health concerns can include congenital deafness and compulsive tail chasing.

Tail Chasing:

Some Bull Terriers develop a compulsive neurologic disorder where the dog turns round and round chasing his tail. As soon as you see this, try and distract him with an exciting game, because allowed to develop, it’s a habit that can become difficult to control.

Dental Disease:

This is a common problem with dogs and you need to watch that tartar build-up on the teeth which can lead to infection of the gums. Brush your pet’s teeth with special dog toothpaste and toothbrush 2 or 3 times a week so that he doesn’t lose any teeth. Bad teeth can affect other organs such as the kidneys and heart.

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.

Grooming:

With his short, smooth coat, the Miniature Bull Terriers requires little grooming. He’ll need a good brush down twice a week to remove loose hairs.

Spaying or Neutering:

This is one of the best things you can do for your Bull Terrier if you don’t want them having puppies. Spaying or neutering decreases the likelihood of certain types of cancers too.

Diet:

Keep your dog’s diet consistent, varying between a top quality commercial produced dog food appropriate to his age. You can include home-made meat, vegetables and rice and some raw meat every now and then. Never feed him human-food such as peanuts, crisps and chocolate. Always have fresh, cool water available night and day.
