Irish Jack Russell vs Chilean Fox Terrier - Breed Comparison

The Chilean Fox Terrier, developed in Chile, is a dog breed which comes from crossing the British Fox Terrier with some of the local Chilean dogs.

The dog is thought to have been developed in the 19th century already, some time between 1790 and 1850.

The dog is known for its skills in catching rats and mice. Known also as the Chilean Rat Terrier, Terrier Chileno or Ratonero, the Chilean Fox Terrier hasn’t achieved formal recognition with any of the leading canine organizations.

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 Chilean Fox Terrier looks almost identical to his ancestors. He stands between 30 – 40cm and weighs between 5 to 9kg.

He is squarely proportioned, he is athletic looking and well muscled with long, slender legs. Many of these dogs are born with naturally short tails, but if not, then the tail is usually docked after the first or second vertebrae. Now that docking is falling out of favor, the breed is losing that distinctive look.

The head of the Chilean Fox Terrier is triangular with the muzzle being somewhat shorter than the Smooth Fox Terrier. The ears of the Chilean Fox Terrier are smallish and high set, being partially erect. The coat of the dog is short and thick and essentially white while the face is usually tan and black.

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 Chilean Fox Terrier is a lively dog with an alert expression. He has become a popular companion dog, being less aggressive than other Terriers.

When you treat him well he becomes a loyal friend and forms a strong bond with his human owners. He gets on well with children who have been taught to respect animals, but he tends to become a bit aggressive around other dogs of the same sex.

Socialization and training however can make him much more relaxed around other dogs.

He is an attractive little dog with his short coat, giving the appearance of being well groomed. He can adapt to country- or city life too. He is such an easy dog to keep too so why not choose him as your 4-legged family member? He promises to make the perfect family companion.

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 Chilean Fox Terrier is a healthy breed who doesn’t appear to have any particular health issues. It doesn’t mean that your dog will be free from disease, but it is worth knowing that a quality diet, fresh water and lots of love and attention does enhance longevity in a pet.

It is to your benefit to know about one or two common diseases that your dog could get.

Bloat:

You’ll notice your pet’s stomach being swollen. Bloat is a disease which can become dangerous because the stomach can twist. Once this happens, gas can’t escape from the stomach and your pet will want to vomit, he’ll salivate and you’ll notice unusual restless kind of behavior. You need to get him to the vet as soon as possible.

Kidney Disease:

This is also a disease that any dog can develop and can be a complication of another pet disease such as Lyme disease. One of the first signs of kidney disease in dogs is drinking more often than usual and also urinating more often.

He’ll lose his appetite and be lethargic and likely lose weight. Kidney disease is a serious disease and you will need to get your pet to the vet as soon as possible.

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 Chilean Fox Terrier is a low maintenance breed and this means you won’t be having to part with any money on grooming sessions for him. He’ll basically require a brushing twice a week.

The Chilean Fox Terrier, as a smaller dog breed, will also require regular dental brushing, as neglecting this can result in dental problems as well as a host of diseases that are associated with gum disease and tooth decay.

Make sure to feed him a quality diet full of vitamins and minerals and ensure he always has fresh, cool water available.

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.
