Greater Swiss Mountain Dog vs Giant Maso Mastiff - Breed Comparison

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.

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.

There has always been the concern with joint disorders in large breed dogs. Both hip- and elbow dysplasia can occur with your Giant Maso Mastiff, more so if you overfeed him as a puppy and he grows too fast.

With hip dysplasia, the long bone of the leg forms incorrectly. This can lead to pain and lameness with your pet.

Also check out bloat. This is a serious illness when the stomach fills with air and can twist. Gastric Dilatation-Volvolvus, is an emergency situation then which is found more often in large, deep-chested dog breeds.

If you see your dog with a bloated stomach and acting in a strange, lethargic way, get him to the vet immediately as bloat can be life threatening.

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.

Grooming:

As an average shedder, the smooth, shorthaired coat is easy to groom, and a good brush twice a week will be adequate.

The Giant Maso Mastiff has floppy ears and therefore these should be checked for ear infections. Wax build up and dirt will need to be checked and cleaned.

His nails will need to be clipped, especially if they don’t wear down on their own and his teeth will need to be cleaned 2 or 3x a week to avoid dental disease.

Diet:

With a large dog breed puppy such as the Giant Maso Mastiff, rapid growth is a risk factor for developing joint and bone conditions. The growth period can last till 12 months and puppies of large breeds should actually have their caloric intake adjusted during this growth period.

It is important to ensure that your puppy grows at a slow, steady rate. If you are feeding dog food from the commercially manufactured range, if you aren’t sure, speak to your vet about large breed dog foods. You want to be sure that this gentle giant of yours receives the best dog food there is, whether commercial branded dog food or your own home-made food. Good nutrition is imperative for the health of your pet.
