Irish Jack Russell vs Brazilian Terrier - 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.

Though its exact origins are questioned it is known that the Brazillian Terrier was developed in Brazil and along with the Fila Brasileiro, are the only authentic Brazillian breeds. In the early 1800’s the Jack Russel Terrier, Fox Terrier, Chihuahuas and Miniature Pinschers were mixed to create the Brazillian Terrier. The Terrier breed was brought to Brazil by Europeans and there were probably both the Jack Russel and the Fox Terrier in the mix. Very popular within its own country the Brazillian Terrier is barely known outside Brazil. They were registered in 1973 even though they have been around in Brazil since the 1800’s. They are both single and pack hunting dogs. They chase and surround prey until the prey becomes too exhausted to run or fight. The Brazillian Terrier is larger than any European or North American Terrier. They are also less aggressive than other terrier types so that pack hunting became possible. They were built to work in the heat for long periods of time. Their stamina far surpassed other terriers as did their resistance to parasites and diseases.

Many farmers and plantation owners came to values them for their ability to hunt down and eliminate vermin on the land and thus help with increased production of livestock and crops. They were so loved by the farmers and plantation owners that they began known as the “dog of the common people”. Yet it was not only the rural folks who valued this breed, but the people of the cities did as well. Because they were good ratters, a reasonable size, affectionate and loyal, many urban households sported a Brazillian Terrier. The breed spread throughout the country.

The Brazillian Terrier was kept mostly pure bred throughout its history but due to lack of pedigrees and paperwork it was not recognized by any kennel club unit 1973 when Brazillian breeders formed the Clube de Fox Paulistinha or CPF. They had a standard developed and created a stud book. By 1991 they were still not officially recognized but the CFP and the CBKC (Confederacio Brasilera de Cinofilia) began the process of establishing acceptable pedigrees and recognition of the breed. The FCI recognized the breed in 2007.

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 Brazillian Terrier is a small to medium sized dog with a white – tricolor (tan and black) coat. It has a narrow chest, a triangular rather flat skull, the tail is docked, folded, half pricked hears, and the body is well-balanced. Its legs are long and athletic, and the coat is very short and very fine. He has round eyes that can be green, blue, brown or gray. They are very much like the Jack Russel in temperament. His expression should reflect that temperament in its eagerness and alertness.

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 Brazillian Terrier is very much like his ancestor the Jack Russell. Like the JR Terrier he is friendly, intelligent, alert, playful, and loves to dig. They are courageous and fearless. They will obey but only if they know and believe you are really in charge. Otherwise they are intelligent enough to be very independent, determined and willful. At the same time, they are utterly loyal to their people. He needs a lot of toys but don’t let him live with other small animals. His hunting instincts may be the strongest of all terriers and he may harm small animals in the home. You have to teach him when to stop barking. Their love of play would consume your entire day if you let them. You should understand the terrier personality before you acquire a Brazillian Terrier.

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 breed is mostly healthy except for hunting accidents and a few generic issues they are susceptible to. This includes things like Dental and eye issues, the usual ear issues, liver issues, allergies, epilepsy and patellar luxation. However, they are more likely to have issues related to hunting than another of these predisposed conditions

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

This is still a working dog and a terrier at that. They are high energy, athletic dogs. Feed a high-quality food at the rate of 1 to 2 cups per day, split into 2 meals. Treat are good for training but if your Brazillian Terrier is not hunting or working in some way, stay away from too much food and treats as he can easily become obese.

Health issues

As mentioned previously, the biggest concern with this breed is hunting accidents or injuries. Look out for ear and skin infections or allergies. For the most part this is a hardy, healthy breed.

Exercise and games

A very energetic dog, the Brazillian Terrier like its ancestors has a need to work off that energy. Yes, he is an urban dog and can live in an apartment, but you better have a dog park or a competition or some place to hunt because his need for exercise cannot be answered by daily walks and running around an apartment. IF your Brazillian Terrier is not stimulated physically and mentally on a daily basis he will become destructive, hyperactive and very, very unhappy. Don’t just stick him in a yard and leave him either as terriers are known to dig and escape and he will too.

They excel at agility, flyball, obedience and confirmation. They love to chase things and they love to explore. Barn Hunt would also be a good game for them. They are very smart, so their physical exercise should be paired with mental stimulation.
