The Koolie, as a breed we know today, originates from Australia. But, before they were breed and imported, they were the mix made of Britain smooth coated blue merle Collie and the Black and Tan Collie from the Highlands of Scotland. The Koolie came to Australia to work as a kennel dog since they are known as the working, farm dog that can adapt to any weather condition. They were bred to be agile and non-aggressive quiet herding dogs, and they have kept most of those good characteristics until today.
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.
Koolie is a medium bred. Their head is small, with a pointy jaw. Ears are pricked, semi-dropped or dropped. Their coat can be smooth or rough, short or medium length, always with the undercoat. The colours can be Red or Blue Merle, solid Red or Black, sometimes with minimal white or cream speckles. They are usually two-coloured or tricoloured, but some of them are actually one-coloured.
Some Koolie have one or two blue, green or yellow eyes. Eye colour is, of course, affected by the gene that creates the coat pattern and eye colour as well.
They are athletic dogs, with fine bone structure but great stamina. Actually, they were breed to be like that – to work hard, be noticeable among the sheep, eat little and be loyal to one person.
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.
Koolie is naturally energetic, playful and affectionate so they are naturally very good to raise with children.
They are known as great obedience dog. They are very famous as the tracking dogs.
Some of them are successful as the rescue dogs, therapy dogs or educators for school children.
This is not a type of dog that will be alone in the house, wait for you and then be quiet while you rest. They need a great deal of activity and they are not such great choice for indoor life anyways. The best thing for them would be the large yard, with somebody home most of the time. They are great if raised in a family, with children and active owners. They will be great for a loner at the farm as well since that is in their blood. They need enough place to run, chase, play, rest on the sun and be active as they please. They get affectionate towards their families, but they will be accepting their new home when they are older just fine.
They are very good at learning. Intelligent, yes, but yet very silly and playful to do what is told all the time. They will surprise you with how quickly they will pick up the new trick but not feeling like doing it every time you would like them to. Everything is a play for them, so it would be best if you know how to play, be affectionate and friendly to become a good owner of this breed.
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.
If you are careful enough, you will choose your Koolie form patiently chosen breeders, after checking the health history of the pup and the pup’s family. Advisable is to do these things in person and never to buy a Koolie from a pet shop.
Sometimes, pups can be born blind or deaf pups. They have the great chance of joint problems because of their extreme activity. Their need to run, jump and play all the time may result in damage to cartilage and ligaments, especially since they are not aware of their age most of the time.
There is a chance that pup has skin allergies or immune system issues if they are growing on a farm near the chemicals used for plants, so be careful what kind of herbicide you use if you have a Collie.
In some rare cases, they suffer from seizers. If untreated, they can cause death. If you decide to take him to a regular vet check, you will have a happy and playful life together.
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.
Whether you choose canned food or dry food, treats as biscuits or left-overs, the quantity is the safest way of keeping the balanced diet for your Collie. They like raw meat and raw bones. Make sure not to feed them with cooked bones because they can do more harm than good.
Since Koolie coat can be very short with the undercoat or a bit longer with undercoat, bristle brushing every 3 or 4 days will be enough for them. Some of them like the water and some of them don’t and that is perfectly fine since there is no need for a regular bath.
Lots of activities and lots of love. They express their love all the time and you can learn a lot from them actually. They like raw bones and from-the-table delicious treats but make sure not to overfeed them.
Games that need them to be fast and think quickly. Running with them, driving a bike with them (but not on the leash!) would be a great fun for them. Why not leash? They are so playful and happy and they tend to jump and run to the side to chase a butterfly or catch the falling leaf.
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.
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.
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.
