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 only breed of dog that is native to Cuba is the Havanese. These little dogs are great companion animals. Sociable and happy, they are very popular in the United States with urbanites. These happy little pups are a Bichon type of dog which was developed from the “Little White Dog of Havana” or the Blanquito de la Habana which is now extinct.
The Blanquito de la Habana was itself developed from another extinct breed the Bichon Tenerife. Then the Blanquito was bred with the other Bichons and poodles in developing the Havanese. It is believed that some of the first people to settle in Cuba were from Tenerife, an island close to Cuba. In the early part of the sixteenth century, little white dogs were brought to Cuba with these settlers. This dog of Tenerife is believed to be the ancestor of all Bichon breeds.
At that time trade with Cuba was highly restricted by the Spanish and so these dogs developed without any crossing from other breeds from outside the country. They grew to be able to stand hot temperatures and they grew a very unique coat – almost like silk. Their coat is soft and light, while insulating them from the tropical environment.
At this time Cuba was the place to be for Europeans aristocrats on vacation. Unlike the British colonies, Cuba had theatres, operas and palacious. When going back to Europe, many took this little white dog with them to France, Spain and England. The Dog of Havannah was a favorite on European soil as well. Many of these dogs taken to Europe were fawn or parti instead of white. Meanwhile back in Cuba, the bourgeoisie were replacing the aristocracy who themselves would soon be replaced by the Revolution.
During the days of the bourgeoisie, the Havanese became very popular household pets. The breed has been a family pet for the last 150 years. At the same time the breed was very trendy in Europe with Charles Dickens and Queen Victoria owning several. They were by now familiar participants in Europe’s dog shows. Finally, with the Revolution, the bourgeoisie left the country in droves with their little white dogs. A genetic pool was then formed in the US. Gene pool from 11 dogs. All the Havanese in the world are descended from those 11 dogs with the exception of the dogs isolated in Cuba and the US. Today the Havanese is one of the most popular and fastest growing breeds in the world.
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.
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 Havanese is a sturdy little dog, a member of the toy group. They weigh no more than 16 pounds (7.3kg) and his body is longer than it is tall. The breed has a unique topline that is not level, but it is straight. His front legs are longer than his hind legs producing the lively gait everyone is used to seeing with a Havanese. With a full muzzle that tapers to the nose, the Havanese does not seem to be short. The skull’s length is the same as the muzzle’s. The head of the Havanese is round in the back and flat in the front.
They have a deep chest, almond shaped eyes that are dark brown and their ears are about halfway down the nose. The long ears hang down the side od the face. They have a long plumed tail that is held high and upward. The standard for the breed and now the laws of the United Kingdom state that there can be no docking of the tail.
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.
Havanese are highly intelligent and eager to please, and they are easily trained so long as you use only positive methods. This can be a sensitive breed, so care must be taken to not scold them harshly. Socialization from an early age is very important. Expose them calmly to a wide variety of new places and new people, always ensuring that the experiences are positive and not intimidating. Gentle, patient training will result in a wonderful companion dog. They are affectionate with people and get along with other nonaggressive pets.
The Havanese is the consummate lap dog. Over time they have become the lovable family companion.
The breed is pretty adaptable being able to live as a companion animal in almost any setting. Just don’t expect your Havanese to go hiking or romp with you on 40 acres in the country.
They are intelligent, love to learn but can be a little stubborn. Train them early as they like their habits and its much harder to train an older Havanese.
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.
A very healthy breed, the Havanese doesn’t have a lot of health issues, but they are not immune to the problems of small breed dogs. The issues they do have are:
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.
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.
Feed 3 to 4 times per day a high quality dry puppy food for toy or small dogs. Feed ¼ to ½ cup each time.
Remember these are small dogs and don’t overfeed. Feed a high quality dry food for small or toy dogs. Feed twice a day at about ½ cup each time.
The breed is generally very healthy.
This breed is not an overly active dog, but he does need some exercise. A nice walk once a day or a backyard to play in. They play inside as well as out. Don’t over exercise the Havanese. They do well in obedience and confirmation more so than agility or fly ball
