Sealyham Terrier vs Irish Mastiff Hound - 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.

The Sealyham Terrier is a rare dog breed originating in Wales. The dog was developed in the 19th century by Captain John Edwardes at Sealyham House. The Sealy has been associated with members of the British Royal Family, but its numbers declined to such an extent that it was listed as a vulnerable native breed by the Kennel Club.

The Sealyham Terrier club was created in 1908 and the dog breed was officially recognised by the Kennel Club in 1911. This dog is now recognized by all the major kennel clubs. The American Sealyham Terrier Club was founded in 1913.

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.

The Sealyham is a dog that stands low to the ground and its height shouldn’t exceed 27 - 30cm and weight should be about 8 - 9kg.

The double coat is considered non-shedding and is wiry and weather resistant. It is nearly always white but can be fawn. They’ve got big heads with dark, deep set eyes. The ears are semi-erect, semi-floppy and the tail is usually docked.

Temperament:

Affectionately referred to as Sealy, there aren't too many of these little dogs left. At one time, they were a very popular terrier breed, but today they are uncommon – almost endangered.

He’s a social dog with his human family but tends to be reserved around strangers. He also tends to be just a little bit more mellow than some of the more rowdier terrier breeds.

He gets on well with other dogs in the home as well as with children. He is an intelligent little dog but is inclined to be stubborn so you have to show him both firmness and kindness and also think about obedience training for him.

He’s amicable and adjusts well to life in the city or the countryside.

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 Sealyham Terrier is such a robust little dog with a distinctive look.

He can be stubborn but he loves his human family and is sociable and amicable with them, slotting in to their way of life. He can be a couch potato or an active outdoor dog – whatever is required of him and he makes and excellent, loving family pet and 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.

This is a hardy dog breed and you don’t hear of many health problems associated with him. It seems as though you might have to watch out for an eye condition known as lens luxation. It's an eye condition with dogs where the lens slips out of position because of weakening of the fibers that hold it in place.

There is a lack of fluid in the eye causing optic nerve damage and this can lead to blindness.

Retinal Dysplasia is another eye problem . This is a developmental malformation of the retina that the dog is born with. Symptoms in dogs are a reluctance to jump off things such as the bed or he may even bump into things.

Atopic Dermatitis is something the Sealyham is more prone to. Its an allergic skin disease which drives a dog mad with its itchiness. Your pet will certainly need treatment from the vet to relieve it.

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.

Provide your Sealy with his own warm, dry bed.

Brush the long, weather-resistant coat at least twice a week. Hand-stripping of the coat will maintain the wiry, hard texture, but because this method can be quite a laborious process, many Sealy owners rather have their dog professionally clipped.

Check inside his mouth for bad teeth as well as inside the ears for signs of infection. His eyes should also be clear and free of discharge.

His nails will also need to be trimmed.

The Sealyham doesn’t require a lot of exercise but he must at least be given a walk every day.

Ensure the vaccines are up to date. They start when your pet is just a puppy. Remember to get your dog to the vet when you suspect that he is ill.

Feed your Sealyham with good food. Make sure you’re feeding your pet a high quality food as this promotes health and longevity. Provide your Santal Hound with top quality food to ensure his health.

Always choose the quality commercially manufactured foods on the market – those that have natural, good ingredients in them. Try to include some home-made food for him which can be simply mixed into the dry kibble twice a week.

There is no need to offer your dog a host of different foods. Dogs want simplicity and consistency. Boiled chicken, brown rice or pasta and spinach, sweet potatoes and carrots is super tasty and nutritious. If you can, also try and include a little bit of raw meat to his diet occasionally as this can go towards ensuring he doesn’t get skin diseases.

Make sure that a constant supply of fresh, cool water is available to your dog.
