Parson Russell Terrier vs Japanese Terrier - Breed Comparison

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.

The Parson Russell Terrier hails from England and is a small to medium sized dog dating back to the 18th century. It is believed that Reverend John ‘Jack’ Russell was the developer of this dog. The Parson has always been involved with England’s sport of foxhunting.

They’re spritely and quick and have been able to keep up on a hunt and take on a fox in its lair. The dog was first recognized in 1990 in the United Kingdom as the Parson Jack Russell Terrier and in America in 1997.

All the top kennel clubs recognize this dog as the Parson Jack Russell Terrier.

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.

Your Parson Jack Russell can live to be between 12 and 15 years but nonetheless he does have some breed-related health issues to watch for.

Eye Disorders:

Eye conditions which can affect this dog include primary lens luxation,cataracts, corneal dystrophy and progressive retinal atrophy. With cataracts the lens of the eye develops a cloudy look resulting in poorer vision and sometimes blindness. Cataract surgery is available for dogs.

Obesity:

Your Parson Jack Russel should be lean and muscular and always full of energy. Avoid feeding him unhealthy treats which can lead to obesity and other health problems.

Parasites:

All kinds of parasites such as ticks, fleas and worms can invade your dog’s body. Roundworms, hookworms and tapeworms can cause havoc with their health and some of these parasites can even be transmitted to humans. It’s why it is important to get your puppy to the vet to be de-wormed and to get his first injections.

Liver Problems:

A liver disorder known as portosystemic shunt can mean that some of the blood supply doesn’t get to the liver and it doesn’t function properly. This will mean the liver can’t remove toxins from the bloodstream effectively.

The Japanese Terrier is an active dog and will require exercise every day. He’ll love to join you on your walks or have ball games in your garden. He can adapt to life in the city or in the country but will always need to have good exercise.

Grooming:

The Japanese Terrier is a medium shedder and you want to be sure then to brush him twice a week to get rid of all those loose hairs.

Diet:

The Japanese Terriers will require the best commercially manufactured dog food, and instead of one large meal a day, rather feed him 2 smaller meals. You can mix some tasty home-made food into his dry kibble from time to time. Excellent home-made food would be something like cooked chicken, brown rice or pasta and some vegetables.

If you can, try to also include some raw meat occasionally. If you’re in any doubt as to how to feed your Japanese Terrier so that he remains healthy, speak to your veterinarian.

Your dog should never ever be without a continuous supply of fresh, cool drinking water.

The Parson Russell Terrier has different coat types – the smooth and rough and both will require regular brushing. Rough coats will require plucking or clipping to avoid matting.

Check his eyes and ears regularly. Look inside his ears for excess wax and dirt which could lead to an ear infection. His nails should also be trimmed.

No Puppies – Spay or Neuter:

The best thing you can do for your Parson Russell Terrier if you don’t want your pet producing puppies is to have it spayed or neutered. Spaying for females or neutering for males decreases the likelihood of certain types of cancers too so it can be beneficial.

Diet:

Diet is hugely important for a Parson Russell Terrier and the food you decide for him can impact his health. Many time those ‘treats’ you feed your pet do nothing more but give him a stomach ache.

It's tempting to pop chocolates, popcorn, nuts and ice cream into your pets mouth when he is so adorable but in the long run it is shortening his life. All he basically requires and needs is a simple, consistent diet of the top commercially manufactured foods mixed with some tasty home made food from time to time.

Boiled chicken, brown rice and vegetables such as sweet potatoes, carrots and spinach will do your pet wonders. Ensure he always has fresh, cool water available to him.
