Pyrenean Mastiff vs Greater Swiss Mountain Dog - Breed Comparison

The Pyrenean Mastiff originates from Spain, descending from ancient livestock guardian-type dogs.

They have always been used as guardians, looking out for livestock and warding off predators.

When you do research you find that there is little information on the exact origins of the dog. It was only in recent years that the dog was taken out of its native region and sent to the USA, but it isn’t recognized by the AKC.

The dog was however recognized by the FCI in 1982.

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.

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.

This is a fairly healthy dog breed, particularly when you consider what a big dog he is. There are always some health concerns to watch for so that you can take steps to get your pet well again.

Dental Disease:

There is tartar build-up on the teeth and this can lead to infection of the gums and roots of the teeth. Rotting teeth can cause pain, but more worrisome they can cause damage to the heart and kidneys as well as the dog's joints. The vet or professional pet groomers can keep your pet’s teeth clean. They can advise you on how to take care of your large pet’s teeth.

Bacterial and Viral Infections:

Diseases such as rabies and parvo can be prevented by means of vaccine.

Obesity:

You can’t afford for a big dog like this to become obese. It’s a serious disease and can put pressure on your dog’s joints and also cause back pain and digestive disorders.

Parasites:

Your dog can be infected with all kinds of worms and bugs such as ticks d and fleas as well as mites. Some of these parasites can be transmitted to you. Your vet can talk about preventive medication.

Bloat:

Gastric Dilatation and Volvulus, commonly referred to as bloat often occurs in dogs with deep chests.

The stomach twists and fills with gas,and blood to the stomach is cut off. Left unattended to, your dog can die, sometimes within half an hour. His stomach is hard and swollen, requiring immediate veterinary attention.

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.

Spay or Neuter:

Have your pet spayed or neutered if you don’t want puppies. Spaying or neutering also decreases the likelihood of certain types of cancers.

Diet:

Nothing but a top quality diet is good enough for your pet. Commercially manufactured dog foods are a convenient means to feed your pet, and there are some excellent brands.

Look out for the ones for extra large dogs and avoid the ones with low quality ingredients. The dry kibble you give your big pet can be made more tasty when you add some homemade food to it about twice a week.

Dogs thrive on simplicity, so boiled chicken, sweet potatoes, brown rice or pasta, carrots and spinach will be wonderful for him when you chop the food up and add it into the dry kibble. Its such a tasty, wholesome treat for your pet.

Some raw meat added in occasionally will contribute to your pet’s heath. Make sure he is never without a constant supply of fresh, cool water.

Grooming:

Brush his coat at least twice a week. Check inside his ears for redness which could indicate an ear infection.

He’s an intelligent pet with lots of energy, so you will need to keep his mind and body active by ensuring he enjoys walks every day. He isn’t a dog that requires running with you on your jogs or cycles.

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.
