Shetland Sheepdog vs American Mastiff - Breed Comparison

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 Shetland Sheepdog was crossed with working collies and brought to the islands. They were bred on the Shetland Islands, United Kingdom.

These little dogs have always been particularly valuable to farmers who used them to herd their sheep.

During the early 20th century other crosses occurred an in 1909 and the little dog received recognition by the English Kennel Club. The first Sheltie to be registered by the American Kennel Club was in 1911.

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.

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.

Every dog, no matter how healthy, can succumb to any one of the many dog illnesses there are.Some of the dog illnesses to look out for include cancer, bloat, ear infections, dental problems, hypothyroidism, skin allergies and obesity among others.

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.

Exercise:

These little dogs have always been farm dogs and they will need a lot of exercise. Even so, with their small size, they can adapt to life in the city or the countryside, but will always need exercise.They love going for walks and playing games with the kids.

Grooming:

Your Sheltie will need brushing every day because the hair can so easily pick up leaves, twigs and burrs. In the warmer months some people prefer to trim the coat themselves or take the dog along to a professional groomer.

Diet:

It is best to feed adult dogs two meals a day instead of one. One can make your dog want to gobble up his food too quickly and this can result in a life threatening condition known as bloat.

How much any adult dog eats will depend on his size, his age and his activity levels.The quality of dog food you buy also makes a huge difference – the better quality the food, the more satisfied your Sheltie will be.

Some of the best commercially manufactured dog foods are convenient and they can be good if you go with the best brands that have high levels of vitamins and minerals in them. Dry kibble can be made more enticing when you add some homemade food into it.

Boiled chicken, sweet potatoes, brown rice or pasta, carrots and spinach will do him the world of good. Chop it up and add small portions to the kibble about twice a week. His wagging tail and prancing antics will be all the thanks you need.

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