Koolie vs American Bulldog - Breed Comparison | Petzlover

Following World War II, the American Bulldog was almost extinct.

Thanks to John D. Johnson from Summerville, Georgia the breed is still with us today. He gathered the best dogs he could find throughout the rural South and bred them back into popularity among his family and other rural families. His father bred the American Bulldog before John did and they have bred them longer than any other in any part of the world. His dogs were regularly used for tracking, hunting, guarding, watchdog and weight pulling. At some point Alan Scott joined Johnson breeding other bulldogs to Johnson's and forming the Standard American Bulldog.

The American Bulldog/ is popular today as a family pet and companion as well as a working dog.

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.

They have a square head, with muscular cheeks and a clearly defined furrow between his eyes. With broad, square and strong muzzles, they have a reverse scissors, scissors, moderate underbite and an even bite. Ears come in a variety of shapes and sizes and eyes can be any color as well. The nose however should be black and lips black as well. Their legs are strong, heavy boned and straight with well-defined muscles in the hindquarters.

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

The American Bulldog is characteristically loyal, brave and reliable. It is a friendly, gentle dog that truly loves children. There is not a hostile bone in his body despite his history and reputation for bull baiting. Though he is protective of its family and affectionate with most, he still needs a human companion who is strong willed and a genuine pack leader. Without this he might become aggressive around other dogs and pets. They are immensely self-confident and they do slobber and drool and will become excited and hard to handle without daily exercise of both their body and their minds.

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.

Though generally healthy, the American Bulldog is prone to a few problems.

Hip Dysplasia

This is a serious issue in many breeds of dogs and is especially prevalent with the American Bull Dog. This may seem ironic in such a short legged dog but it is unfortunately very common. It is a genetic disorder that causes the bones in the joint to separate and causes the dog much pain and lameness.

Skin and Ear Issues

Due to skin folds you need to be care and watch for irritation and infection in the folds. They are also prone to ear infections.

Obesity

The American Bulldog is prone to overeating and all the health issues that presents. With short legs and a genetic predisposition to arthritis and hip dysplasia, obesity is a real health risk for your bulldog.

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.

Feeding Puppies

Three times a day from 12 weeks to a year for a total of 3 cups per day.

Feeding Adults

After 6 months cut back to one cup twice a day of high quality dry dog food.

Bulldogs will eat anything at anytime and are prone to obesity. Don't overfeed them.

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.
