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.

The Kerry Blue Terrier hails from Ireland, with the name of the dog coming from a place known as County Kerry, and Blue being the color of the dog's coat.

The Kerry Blue was originally bred to control rats, rabbits and otters and was actually a working dog for a host of different jobs.

It was in 1922 that the United States Kerry Blue Terrier Club was founded and recognized by the AKC in 1924.


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.


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 Kerry Blue is a small dog standing at between 44 to 51cm and weighing anything between 15 and 18kg. He has dark eyes which give him that typical alert Terrier expression.

The ears are small and are carried up before flopping down. The high-set tail has always been customarily docked, giving him a compact, jaunty appearance but these days, the tail tends to be left long, curling somewhat over the back.

He has a coat which is quite wavy or curly and comes in different shades of grey or blue, while the puppies are born black, gradually becoming more blue. The dog is considered to be hypoallergenic as it doesn't shed a lot.


Kerry Blue Terriers are strong willed dogs, but with training and socialization they respond well to instructions such as sit, come, lie-down and stay. As a Terrier breed he is feisty, lively, strong-willed, stubborn, independent and impulsive. They are loyal and affectionate towards their owners and are amicable with children and pets in the home.

Training and socialization develops a balanced attitude around his human family, other animals in the home and around strangers. He is an active dog too so whether he lives in the city or the countryside, he will require a lot of exercise as he is full of life.

You can’t just put him in the backyard and forget about him. He is an intelligent, social dog who will only do well when he is counted in as a family member.

Health Problems

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 -


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.


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.

You aren’t going to be running to the vet often with your Kerry Blue as he is a healthy dog breed. However there are some common dog diseases that even the most healthiest of dogs can succumb to.

Always feed your dog the very best food there is so that he has a strong immune system that can fight off disease.


This is the inward rolling of the eyelid which can irritate the dog’s eye and even cause vision loss. Surgery can treat the problem.


Every dog can succumb to cancer. You may well find a lump or even detect a sore that won’t heal. Treatments for cancer can include medicines, chemotherapy and surgery.

Hip Dysplasia:

This is an inherited condition to do with the hip joint. It can result in pain for your dog and even lameness. When you discover your pet no longer wants to play and he battles to get up after lying down, he will need to go to the vet. Dogs with this debilitating disease should never be bred.

Caring The Pet


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


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


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.


The Kerry Blue’s coat doesn’t shed a lot but it’s a curly coat that will require brushing at least twice a week. He will also require clipping and trimming if you want to keep the coat manageable.


Nutrition is a key part of a healthy Kerry Blue Terrier and instead of just plonking down a bowl of dry kibble every day, make his mealtimes something to look forward to, more sustaining and more interesting.

Top quality kibble is good every now and then but try mixing in some cooked chicken, brown rice, pasta and vegetables occasionally as well as a little bit of raw meat. You will be rewarded with bright eyes, a wet nose, bushy, wagging tail and less trips to the vet.

Make sure there is always a supply of fresh, cool water for him.


Active and lively, your Kerry Blue will need lots of robust exercise – a daily walk as well as ball games which ensure his muscles are kept strong and toned. Not only that, this exercise is important for keeping him fit and also mentally alert.


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.

When you bring a Kerry Blue Terrier into your home and your life, you’re going to have a jaunty, lively, comical pet in your home, as he certainly has the reputation of making people laugh.

He is such an intelligent dog too and has no difficulty with learning new tricks. He takes his role of watchdog seriously too, as he loves his human family and wants to be looking out for them.

When you bring a Kerry Blue Terrier into your home, you can be assured of jolly good fun from a true canine companion.
