History

english mastiffThroughout most of history there have been images created by people of very large, sturdy dogs that they shared their space with. The English Mastiff can trace some part of her ancestry to these same dogs. This breed is thought to have come from the stock of ancient breeds such as the Alpine Mastiff, Pugnaces Britanniae and Alaunt. The Mastiff in general has then become a main descendent of many other breeds of dogs since the 1880’s. The images of these types of dogs goes back to the 5th and 6th century.

There is no genetic evidence linking these dogs to the modern Mastiffs and the English Mastiff, but the resemblance is obvious. There is anecdotal evidence that these Mastiff type dogs were exported from England – the English Mastiff – to Greece to hunt game but were also used as war dogs by the Celts. The Alaunt was probably used the Normans and bred by the Alans. Writings and images throughout these times depicted a dog that looked very much like today’s English Mastiff. Some speculate that the English Mastiff came to the United States of the Mayflower.

There was a decline in the English Mastiff in its homeland in the 1800’s following the Cruelty to Animals Act of 1835 which prohibited owners and trainers from baiting animals. Then in the 19th century, prior to the first World War, systematic breeding programs began with J.W. Thompson. His first English Mastiff was a female named Dorah. Dorah’s ancestors included dogs from Thompson’s Grandfather. Captain John Garnier of the Royal Engineers also had dogs that contributed to the development of the English Mastiff.

During this time some breeders got away from pure type and began to breed for other factors. In the late 1800’s, Edgar Hanbury and Mark Hanbury Beaufoy began restoring the breed to its original soundness. One of their dogs was exported to the US were breeding to soundness continued until the First World War reduced the number of English Mastiffs around the world. By the time the war ended there were no English Mastiffs outside of England.

There was a dog in Canada named Beowulf and direct descendent of imports from Britain, who came to the States after the war and began to re-establish the breed on this continent and registered with the American Kennel Club. Yet as of 1945, the contribution from North

Breeding was stopped again for World War II and started again after the war. Many of these puppies died of distemper. Only one female had pups that were able to grow up into adults. North America sent dogs to England at this time and all of the Mastiffs from that time, could be traced back to Nydia and the 14 North American Mastiffs. Since then the breed has been restored slowly in Europe, North America and everywhere in the world.

The English Mastiff is known by his massive head with a black mask and comes in a wide variety of colors. He is also known as a gentle giant because of his personality and the love he has for his people.

jack russell terrierThe popular Jack Russell Terrier was developed in Devonshire in the south of England in the late 1800's so as to hunt foxes.

Often believed to be the Parson Russell Terrier, the Jack Russell Terrier was developed by Parson John Russell. This is where the dog gets his breed name from. Some people get the Jack Russell Terrier a little bit mixed up with the Parson Russell terrier, when it fact its actually a different breed, but sharing a common ancestry.

The Jack Russell Terrier is smaller than the Parson and bigger than the Russell Terrier. The breed became known in the U.S. by the 1930s and the Jack Russell Terrier Association of America wanted recognition by the American Kennel Club, which was granted in 2000.

Eye disorders:

Lens luxation is actually a common hereditary disorder in these dogs, but even so, with good care, your dog isn’t likely to battle with it. What happens is that the lens in the eye becomes displaced. There are two types, with Posterior luxation being the lesser severe one.Treatment is available.

Musculoskeletal conditions:

Patellar luxation is an hereditary disorder affecting the knees of the dog. The kneecap slips off the groove where it sits and you may notice your dog running while holding his hind leg in the air. It can sometimes slip back in place and then you see your dog running in his usual way. It becomes more serious when it affects both legs.

Caring The Pet

english mastiff dogs - caringThis is an enormous dog that grows quickly. It is important to feed them properly as they grow. If he doesn’t get what he needs as a puppy you will not be able to make it up to him later on.

Feeding the puppy

The English Mastiff puppy needs good nutrition for growing properly.

From 12-16 weeks of age feed him 3-4 cups a day of a high protein, high quality dry food. Break this up into 3-4 meals.

From 4 -6 months of age feed him 8-10 cups a day of a high protein, high quality dry food. Break this up into 2-3 meals.

From 6-18 months of age feed him 8-12 cups a day of a high protein, high quality, dry food. Break this up into 2-3 meals.

Feeding the adult

The English Mastiff is still growing from a year to 18 months. Starting at 18 months feed him 10-12 cups a day of high protein, high quality dry food. Break this up into 2 meals.

As your Mastiff ages, cut down on the protein and feed a dry food appropriate for his age.

Points for Good Health

The English Mastiff is a very large dog that should not be allowed to get obese since he is prone to dysplasia. He needs protein throughout puppyhood and until he is about 8-10.

Games and Exercises

This is a couch potato if you let him be. Make sure he gets at least one long walk per day or he will tend to gain weight. Play with them off leash about an hour every day.

Exercise:

jack russell terrier dogs - caringThe Jack Russell Terrier isn’t just a small dog that can be left to his own devices. He will need proper training and socialization early in life to make him obedient and better to get on with.

He may be a small dog, but he certainly won’t do in the city where he is cooped up in a place with a handkerchief of a garden. He needs lots of space to run and play. He wants his human family to join in with walks, hikes, ball games and swimming.

Diet:

You can buy excellent commercially manufactured dog food which caters for energetic small dog breeds like the Jack Russell Terrier.

Once you have selected the best one for your pet, with dry kibble being better in terms of dental health - you can also add in some brown rice, vegetables and cooked chicken. This is highly beneficial to all dog breeds. A little bit of raw meat can sometimes be added in too.

The bottom line is to to prevent your pet from eating foods high in preservatives, additives and fillers. Never leave your pet without a constant supply of fresh, cool water.
