The Tibetan Mastiff is still considered to be a primitive breed originating in Tibet centuries ago. The breed was developed to guard property and livestock. They still do this as well as being a much loved family dog and a show dog as well. There is very little history that is documented for the breed prior to the 19th century.
Believed to be centuries old with ancestors who are mastiff like dogs that developed into two different types of Tibetan Mastiffs. These types are the Tsang-Khyi and the Do-Khyi. The Tsang Khyi were guardians for Tibetan monks, while the Tsang-Khyi guarded flocks for nomadic shepherds and in villages.
The first Tibetan Mastiff was imported in 1847 to England and presented as a gift to Wueen Victoria, from India’s Viceroy. By 1873 there was an English Kennel Club and the breed was labeled a large dog from Tibet and entered into the EKC Stud Book.
The next year the future King Edward VII, brought another two Tibetan Mastiffs to the United Kingdom to show in 1875. The first breed club began in 1931. The world wars interfered and no new dogs were imported to England until 1976. Two dogs were given to the President of the United States in the late 1950’sbut were not bred and it wasn’t until 1970 that any more were imported. The US Tibetan Mastiff Club was not founded until 1974 and they were first entered in a National Specialty show in 1979.
In 2007 the AKC recognized the breed as a working dog since 2007. It’s hard to find a purebred Tibetan Mastiff in Tibet anymore.
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.
Both types of Mastiffs can be present in the same litter, so that both larger and smaller pups are present. Both types are well-muscled and structured. Today’s dogs being developed in China and the West are much larger than the previous ones. These dogs would be less useful to the nomads and cost too much to feed. Today’s dog is very large with a large head and a long double coat. This coat can be black, brown, gold, and blue, with or without tan markings. There are now a few white Tibetan Mastiffs being bread.
The breed standard for the Mastiff is different in the West than in the East. In the East the breed is broken into two categories – the Lion Head and the Tiger head.
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.
With extreme caution and only if raised together
Guard dog
Not good. No apartments and cant deal with heat
Highly intelligent very stubborn and independent
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.
Though considered a primitive dog and isolated for several centuries, so they should not have as many genetic or inherited conditions as other dogs with more cross and in-breeding. These are the potential health issues they might develop:
Elbow and Hip dysplasia – can lead to lameness and arthritis.
OCD Osteochondrois Dissecans – this is also an orthopedic condition when the soft tissue growth is abnormal in the joints. It is painful and the joint is stiff. Don’t breed a dog that has this condition.
Panosteitis – Canine growing pains. Inflammation of the long bones in large dogs as they grow. They will eventually out grow it. Pain can be managed through medication.
Autoimmune Hypothyroidism – Hormone deficiency leading to flaky skin, weight gain and lack of energy. Can be managed through medication.
Canine Inherited Demyelinative Neuropathy – If your Tibetan Mastiff is going to have this condition, they will have it by six weeks of age. Weakness in the hind legs leading to paralysis.
Bloat – deadly if not treated immediately and related to dietary habits.
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.
Don’t feed the puppy too much protein as you want to prevent Panosteitis and growing too quickly. Do not overfeed. Feed 4-5 cups of high quality large breed puppy food in 3-4 meals day.
4 to 6 or more cups of a high-quality dog food daily, divided into two meals. To avoid bloat do not feed before or after vigorous exercise.
Calm and laid back when inside.
They need 20-30 minutes of vigorous exercise and play daily. They prefer to play with other large dogs.
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.
