Japanese Terrier vs Jack Russell Terrier - Breed Comparison

The 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.

The Japanese Terrier is native to Japan and is a rare pure bred dog. It is believed that the dog comes from Smooth Fox Terriers who arrived way back in the 17th century.

Certainly he looks very much like a regular Fox Terrier. It is thought that these smooth Fox Terriers were then interbred with local, Japanese dogs and used to hunt rats. Gradually he became a lap dog and companion.

Planned breeding of the dog began in 1920, and it was in 1930 that the dog was admitted to the Japanese Kennel Club with a breeding program being started.

Today you will find the Japanese Terrier in his home country and small numbers elsewhere. He was admitted to the United Kennel Club in 2006.

Some common dog disorders you might want to be aware of are -

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.

The Japanese Terrier has no particular health issues and has a lifespan of 12 – 15 years if looked after well.

There are always one or two illnesses to watch out for such as eye- and ear infections. Some dogs also develop conditions such as Patella Luxation. This happens when your dog's kneecap is dislocated. It can only be returned to its normal position when certain muscles in the back legs are relaxed and lengthened.

With this condition, your dog holds up one of his hind legs. This condition is more prevalent in small dog breeds.

Exercise:

The 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.
