Koolie vs American Mastiff - Breed Comparison | Petzlover

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 Koolie's ancestors were both the smooth coated blue merle Collie as well as the Black and Tan Collie. The dog hails from Australia.

Looking much like the Heeler dog, the Koolie is thought to have got its name from German immigrants to Australia who couldn’t pronounce the name ‘collie’ properly, so the name came out as Koolie. The Koolie of today is a product of a cross between the German Koolie and the Australian Dingo.

The dog has been around for a long time and in 2000, the Koolie Club of Australia was formed. It was in 2004 that the Koolie was recognized by the Australian Sporting Registrar. In May 2006, the Stockdog Committee of the Australian Shepherd Club of America accepted the Koolie as a recognized and accepted herding breed.

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.

Known also as the German Koolie or German Collie, the Koolie is a working- or herding dog standing at between 40 – 60cm in height and weighing up to 24kg.

The Koolie's coat is a merle coat pattern in red or black and possibly with some tan and is mostly short and smooth, though it can be medium length too. Depending on the coat color – red or black – the nose and eyes can be either brown or black, although eye color can also be blue or yellowish.

Temperament:

The Koolie is such a wonderful pet who has some excellent characteristics to his name. He is active, energetic, fun, clever, friendly and playful, but if you have him trained and socialized he becomes even more of a great family pet. He is intelligent too and will require an owner who is steady, firm, fair and consistent. You wouldn't call him an aggressive dog

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.

Many people today like the idea of a ‘wild’ animal as a pet, and the Koolie, with his Dingo ancestry, can be a challenging dog breed to keep. People eventually blame these animals for having a poor temperament – meantime all they are essentially, are high-energy animals.

If you keep a Koolie, it will be better if you were a firm, kind, patient, consistent dog owner who understands the special needs of these kinds of dogs. They’re an energetic, care-free animals who will do better on a large property or farm as he is lively and will need a good deal of exercise.

He is quite capable of being a splendid pet with training and socialization and will settle down well to family life when he is loved and cared for.

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.

The Koolie is a long-lived dog and there are records of it being able to reach 18 years of age. Because they have a diverse gene pool, you won’t find many genetic problems with this dog.

It is always wise when you’re the owner of a dog, to look out for his health and wellbeing -

Vaccination:

This is to prevent your Koolie picking up fatal diseases such as distemper and parvo-virus. Dogs can be vaccinated from 6 weeks of age for protection.

Parasites:

Working dogs like the Koolie are susceptible to parasites such as tapeworm. Worming of your dog can be included in your vet visit. Dogs with worms may show tell-tale signs such as being pot bellied, very pale gums, anemia and a dull, thinned coat.

A look at his droppings may reveal white segments or worms. Fleas are another kind of parasite and they breed quickly in warm months. Mange is a skin disease caused by small parasitic mites which can actually live inside the hair follicles of dogs. Veterinary treatment will be required.

Heat Stroke:

This is when your pet’s temperature rises out of control. Dogs pant to reduce their body temperature so a dog puffing heavily is putting in extra work to reduce his body temperature.

Never leave you pet in a boiling hot car as the body becomes weak and he has difficulty with breathing. Without immediate treatment, the dog will collapse and die.

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.

Training:

The Koolie is an intelligent dog that will benefit from training and socialization to make him obedient and able to cope in diverse situations.

Exercise:

These dogs show an untiring enthusiasm for exercise and work and wherever you live, you will need to ensure that he gets regular exercise.

Diet:

Only the very best - both home-made and commercially manufactured food - will be good enough for this energetic dog. Good quality food ensures health and longevity. Always see that there is a constant supply of fresh, cool water.

Relaxing Time:

Make sure that your dog has a warm, dry place to sleep inside and that when outside, he has a cool, sheltered spot from the sun.
