Irish Jack Russell vs Greater Swiss Mountain Dog - Breed Comparison

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.

Hailing from Switzerland, and one of its oldest dog breeds, the Greater Swiss Mountain Dog has a dubious history in that there are a number of theories as to its origin. He is closely related to the Bernese Mountain Dog, Saint Bernard and Rottweiler.

Of all the theories, the one that says he is descended from large, mastiff-like dogs is a popular one. He used to be a herding- and guard dog, but also was used to pull carts of farm produce.

It was in the 1900s that the dog’s numbers started dwindling. In 1908, canine researcher, Albert Heim recognized the dogs as being large members of the Sennenhund type, a family of four breeds that includes the Greater Swiss Mountain Dog.

He wanted to see the dogs recognized as a separate breed and the Swiss Kennel Club listed the Greater Swiss Mountain Dog in 1909.

In 1968 they were brought to the United States and a club for them was formed. The dog was recognized by the American Kennel Club in 1995 with the dog being recognized as a member of the Working group.

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.

The GSMD or Sennenhund, as his name is shortened to, is a fairly healthy dog breed, with very few health issues.

He has an average lifespan of 10 to 12 years, and although not likely, he can suffer from minor problems such as gastric torsion as well as female urinary incontinence. If your female dog is dribbling urine in her sleep, there are a number of reasons that can be causing it - bladder infections, a medical condition or a weakened bladder with spayed female dogs.

It is certainly time to get your pet to the vet who will recommend a urinalysis.

Grooming:

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.

Diet:

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.

Diet:

The Greater Swiss Mountain Dog is a robust dog and thrives on a diet of kibble to raw meat to some cooked home-made food such as chicken, brown rice and vegetables.

A serious issue with the GSMD is overfeeding, resulting in uncomfortable digestive problems and of course, obesity.

Exercise:

Your GSMD isn’t a dog that is going to require a lot of exercise like some of the other dog breeds there are, but still his working career of the past requires that he still be taken on daily walks, enjoys ball- and rope games and to go swimming.

Grooming:

Brush your dogs coat at least twice a week to remove loose hears. Other grooming aspects include cleaning the ears to avoid infection, clipping his nails and brushing his teeth at least twice a week.

If you’re not sure how to do all these things, there are useful accessories for dogs that allow you to do all this grooming on your own. Your vet can also show you how as these are all things that will require ongoing attention.
