Parson Russell Terrier vs Irish Jack Russell - 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 Parson Russell Terrier hails from England and is a small to medium sized dog dating back to the 18th century. It is believed that Reverend John ‘Jack’ Russell was the developer of this dog. The Parson has always been involved with England’s sport of foxhunting.

They’re spritely and quick and have been able to keep up on a hunt and take on a fox in its lair. The dog was first recognized in 1990 in the United Kingdom as the Parson Jack Russell Terrier and in America in 1997.

All the top kennel clubs recognize this dog as the Parson Jack Russell Terrier.

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.

The ears are floppy wit the tip pointed forward. The tail has always been docked but when left long it it held high, slightly curving over the back.

Temperament:

Feisty, brave, cheeky and alert, the Parson Russell Terrier is an energetic dog who gets on well with children as he knows that this is essentially where his games come from.

He is bold and clever and you’ll be able to have him trained and socialized without any trouble. These little dogs are full of life and they are protective of their humans and their property, making excellent watchdogs.

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.

In general the Parson is a friendly,loving dog, fairly small but packed full of feisty personality.

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.

Your Parson Jack Russell can live to be between 12 and 15 years but nonetheless he does have some breed-related health issues to watch for.

Eye Disorders:

Eye conditions which can affect this dog include primary lens luxation,cataracts, corneal dystrophy and progressive retinal atrophy. With cataracts the lens of the eye develops a cloudy look resulting in poorer vision and sometimes blindness. Cataract surgery is available for dogs.

Obesity:

Your Parson Jack Russel should be lean and muscular and always full of energy. Avoid feeding him unhealthy treats which can lead to obesity and other health problems.

Parasites:

All kinds of parasites such as ticks, fleas and worms can invade your dog’s body. Roundworms, hookworms and tapeworms can cause havoc with their health and some of these parasites can even be transmitted to humans. It’s why it is important to get your puppy to the vet to be de-wormed and to get his first injections.

Liver Problems:

A liver disorder known as portosystemic shunt can mean that some of the blood supply doesn’t get to the liver and it doesn’t function properly. This will mean the liver can’t remove toxins from the bloodstream effectively.

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.

The Parson Russell Terrier has different coat types – the smooth and rough and both will require regular brushing. Rough coats will require plucking or clipping to avoid matting.

Check his eyes and ears regularly. Look inside his ears for excess wax and dirt which could lead to an ear infection. His nails should also be trimmed.

No Puppies – Spay or Neuter:

The best thing you can do for your Parson Russell Terrier if you don’t want your pet producing puppies is to have it spayed or neutered. Spaying for females or neutering for males decreases the likelihood of certain types of cancers too so it can be beneficial.

Diet:

Diet is hugely important for a Parson Russell Terrier and the food you decide for him can impact his health. Many time those ‘treats’ you feed your pet do nothing more but give him a stomach ache.

It's tempting to pop chocolates, popcorn, nuts and ice cream into your pets mouth when he is so adorable but in the long run it is shortening his life. All he basically requires and needs is a simple, consistent diet of the top commercially manufactured foods mixed with some tasty home made food from time to time.

Boiled chicken, brown rice and vegetables such as sweet potatoes, carrots and spinach will do your pet wonders. Ensure he always has fresh, cool water available to him.
