Irish Mastiff Hound vs Irish Jack Russell - Breed Comparison

The Irish Mastiff Hound is a huge dog – a mix of the English Mastiff and the Irish Wolfhound.

Both of these dogs have been around for a long time and actually have ancient histories. The Mastiff for instance has origins that date back to ancient times in China, while the Irish Wolfhound has origins that date far back to 391 AD.

Today this dog is regarded as an excellent companion for any home.

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.

This is a large crossbreed which can stand at 85 to 91 cm in height and weigh in the region of 47kg to 74kg.

He essentially has the short, smooth coat of the Mastiff but other dogs may well inherit the longer, more wiry coat of the Wolfhound. Coloring of the coat can be quite varied and can be brown, grey, white, tan or black. Some dogs take more after the Mastiff while others have more Wolfhound characteristics. They have a large head, some have a somewhat wrinkly face because of the Mastiff side, the ears are fairly small and floppy and the tail is long.

Temperament:

Even though they're so huge, these are easy going dogs that are able to fit in well with most human families. Described as gentle giants, they are loving, loyal, easy-going, even-tempered and eager to please.

The Irish Mastiff does well in the city or in the country because he isn't particularly active and will be happy to have a comfortable spot to lie close to you, however with such a large dog, you will certainly need a garden.

Irish Jack Russells are small dogs standing at roughly 18 to 35cm and weighing in the region of 5 to 8kg for both males and females.

He looks much like your regular Jack Russell but he has shorter legs, and where the regular Jack Russell has an essentially white coat with orange-tan patches, the Irish Jack Russell can be solid tan or other color variations such as red, brindle, black and tan.

The coat can be short or fairly long and coarse. The Irish Jack Russell is a sturdy, compact dog with a flat skull, brown eyes and ears which are semi-erect, semi-floppy. He has a bright, alert, intelligent look on his face. The tail is set fairly high and has always been docked but these days it is inclined to be left long, taking away from the dog’s nice compact look.

Temperament:

The Irish Jack Russell is perhaps more placid than the regular Jack Russell and that is why he can adapt to life in the city or in the country. They’re intelligent dogs and therefore easy to train and have socialized.

Even though he is a small dog, training and socialization is important as he is a feisty, stubborn, know-it-all little dog. These are dogs which can become possessive of their owner and they can become quite aggressive when protecting their family. He is a highly trainable dog but it is important to have him trained as he tends to be aggressive with other dogs.

He is busy, active, happy and inquisitive and will require regular exercise to prevent him becoming restless and destructive. He has been a working terrier and he always wants to be busy.

Your big Irish Mastiff Hound is cool, confident and calm. He isn't particularly energetic and as long as he gets a nice walk as well as some mental stimulation, he'll be happy, wanting to spend a good part of the day lying close to where you are.

Socialization and training will be good for him and he learns easily. He is just a big gentle giant who promises to make you a wonderful canine friend.

The Irish Jack Russell is a self-confident, energetic dog who will like nothing more than to be involved with everything you’re doing. The busier he is the better, and because he has strong hunting instincts you may find him digging in your garden for rats.

Have him trained and socialized if you want to avoid certain problems with him and remember to exercise him and provide him with the attention he craves.

He is a social dog and will pine away if you just leave him to get by on his own. Make sure that he becomes every bit as part of your family as everyone else and he promises to make you a loyal, devoted companion.

Many people find giant dogs irresistible because they're usually gentle, patient and loving. However, it is their very size which makes them more prone to certain health concerns and gives them a shorter lifespan.

It is why it is so important to ensure you feed your pet a healthy diet to ward off illness. A large dog like the Irish Mastiff doesn't have a particularly long lifespan, and with good care he can get to 9, 10, 11, 12 years of age.

Hip Dysplasia:

This condition is more common in large dogs and it can lead to joint degeneration, arthritis and pain. Your pet may even be reluctant to get up and greet you when you come home which can be very sad. Vet intervention will certainly be required.

Dilated Cardiomyopathy:

This heart disease is commonly seen in large dog breeds where the heart becomes weak so that it can't pump blood throughout the body. Coughing, difficulty with breathing, weakness and lethargy are just some of the symptoms of this disease and will also require veterinary intervention.

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.

Grooming:

He has a short coat, and grooming of this laid-back dog will include brushing him twice a week, trimming his nails and making sure that you check inside his ears for ear infection.

Diet:

Large dogs have special nutritional needs, particularly because they are more prone to illnesses such as hip dysplasia. You want to make sure that the foods he eats are rich in Omega-3 fatty acids, glucosamine, chondroitin, amino acids and antioxidants because these will ensure proper joint health.

You've got to be careful what you feed a large breed dog because of the weight management issue too. Excess weight puts stress on the joints and promotes the development of osteoarthritis. Speak to your vet about portion control and meat protein for your pet and how to ensure excellent nutrition to avoid common dog illnesses.

Fresh, cool water needs to be available to your pet every minute of the night and day.

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.
