Irish Jack Russell vs Giant Maso Mastiff - Breed Comparison

The Giant Maso Mastiff is a fairly new dog breed so you aren’t going to find much history on him.

The breed was only started in 2001 so as to create a mastiff dog that would have fewer health problems and therefore have the chance to live longer. The Giant Maso came about because of a mix between the Old English Mastiff and the Cane Corso Italiano.

As stated, breeding began in 2001 and the dog has inherited intelligence and protective instincts from both these dogs.

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.

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.

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.

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.
