Icelandic Sheepdog vs American Mastiff - Breed Comparison

There are quite a few different dog breeds that fall under the name of Spitz-type dogs, and in fact they have a number of similar characteristics, one of which is that they have some wolf-like features. They typically have the thick coat with undercoat and the erect, pointed ears and slanted eyes.

There is definitely a strong link between the Spitz type dogs and wild wolves. The tail too is feathery and can curl over the back of the dog.

The Icelandic Sheepdog, a native dog to Iceland, is a Spitz type dog which originates from the dogs brought to Iceland by the Vikings. The dogs have always been used to herd sheep, and they resemble dogs found in graves in Sweden and Denmark.

The dog at one time was facing extinction in the late 20th century, but in 1969, the Icelandic Dog Breeder Association was established to restore and preserve the breed. The Icelandic Sheepdog gained AKC recognition in June 2010.

The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.

The Icelandic Sheepdog is a smallish to medium sized dog standing at 40 to 45cm in height and he can weigh anything between 9 and 14kg.

His double coat can be short or long, straight or wavy and in a mix of colors such as grey and white or tan and white, black, tan and white, cream or chocolate. Even though they come in a number of predominant colors, these colors are always accompanied by white markings.

He has a longish muzzle, much like the wolf, giving him an alert, foxy appearance. He has a muscular, rectangular body with strong, straight legs with dewclaws on both the front and hind legs.

Temperament:

Your social, energetic dog will require socialization and training which does him the world of good, turning him into a well-adjusted, obedient dog.

He is an intelligent dog, and training him won't be difficult as he is eager to please. These are social dogs which love being part of the family and they don't like being left outside day after day with little human intervention. He is a lively, confident breed, gentle and not at all aggressive.

This crossing of the English Mastiff and the Anatolian Mastiff resulted in a Mastiff with a much drier, less drooling mouth than the other Mastiffs. This is a giant, massive dog – powerful and muscular. With a wide head that is rectangular rather than square. Their eyes are dark amber, and their ears are high on their head and rounded. With a medium size muzzle, black mask and heavy head, the American Mastiff is a handsome dog.

Their chest is broad, deep with ribs that extended backward. He has strong legs that are parallel and wide set. He also has a long tail. Puppies of the American Mastiff are born almost black and as they grow their coat color lightens. In addition, it is important that they have a wrinkled forehead as well and a scissors bite is preferred.

The Icelandic Sheepdog is such a good all-round family pet. He is alert, intelligent, social, playful, loyal, loving and brave.

He is friendly too, getting on well with children and any pets you have in the home. He is essentially a working dog, so you shouldn’t think of owning him as a pet if your lifestyle is centered around the TV and the couch for the best part of the day.

This is an energetic dog who wants lots of action during the day. He is a dog that badly wants to be part of the family and in exchange for looking after him well, he’ll promise to be an exceptional pet.

A love of children and devotion to his pack (family) is bred into the American Mastiff. He is non-aggressive unless you threaten his family or his children. Then he becomes courageous, protective and defensive. This is a gentle giant most of the time, however due to size and the need for strong leadership, the American Mastiff should be socialized and trained early. If they are socialized and trained they will be calm, gentle dogs. They will remain protective and alert, but they will be friendly with strangers. They love to please their people and being highly intelligent they learn fast.

Your pet will reach 12 to 14 years of age with good care and is regarded as a generally healthy dog breed. However, they can be prone to a few health conditions, and these include hip dysplasia and diabetes.

Diabetes:

Mercifully for your pet, diabetes is considered a manageable disorder. When your pet doesn’t produce insulin or can’t utilize it normally, his blood sugar levels rise, resulting in hyperglycemia.

If left untreated, your pet can land up with a host of complicated health problems. Diabetes can be classified as either Type 1 or Type II, with the more common form in dogs being Type 1.

American Mastiffs seem to have fewer health issues than other larger giant breed dogs. However, they can experience allergies as many large, wrinkled dogs do. They also might have a tendency toward eye issues, hip dysplasia, cancer and heart disease. Bloat might be the most life-threatening issue many American Mastiffs experience.

Diet:

Feed your energetic Icelandic Sheepdog a diet which is appropriate for his age and activity level. Don't just feed him the best commercially manufactured dog food, but give him some cooked chicken, brown rice and vegetables mixed into his kibble as a tasty treat. Also, dogs are carnivores, so include some raw meat into his diet from time to time. Clean, cool water should always be available.

Grooming:

The Icelandic Sheepdog has a thick double coat, with the outer coat being longer and the hair being shiny and glossy. These dogs shed quite a bit with seasonal shedding too so twice-weekly brushing will be necessary to keep the fur free of loose hair. His nails should also be checked regularly and his teeth should be brushed a couple of times a week too.

Exercise:

Icelandic Sheepdogs are athletic, active dogs that require a lot of exercise to keep them in good physical shape.

He loves all kinds of games and outdoor activities, one of which will be going with you for a walk every day. He makes a wonderful companion for those people going on long hikes.

Giant breeds like the American Mastiff are known for growing rapidly as a puppy and therefore proper feeding and nutrition is essential. The slower your American Mastiff grows, the better. Make sure your puppies get enough phosphorous and calcium in their high calorie diet. Free feeding is not recommended. Feed puppies up to 4 small meals per day and feed adults twice a day.

Health issues

As previously mentioned this breed is a fairly healthy one, There, are however, certain evaluations you should do with your American Mastiff puppy to be sure she is in good health. These tests would include an elbow and hip evaluation to check for dysplasia. He should have an ophthalmologist and cardiologist examine him as well. Most American Mastiffs will not have any problems, but these evaluations will help to prepare you if they do. The wrinkles in your dogs; face, around the eyes and muzzle must be kept clean as they can become infected if you don’t.

Exercise and games

Unlike the way he looks, the American Mastiff is not a couch potato, but neither are they a high energy, exercise machine. They do well living in apartments or homes, with or without a fenced in yard. They need a long walk every day. They need mental stimulation through exercise and games. Make sure they learn to love to play so that they don’t become lazy as they age.
