Yes and no. A warmblood is as a general rule a description of any horse that is neither a hotblood (Arabian, Thoroughbred, or Akhal-Teke) or a coldblood (Draft). The majority of horses fall under the 'warmblood' heading. That being said however, many European sport horses are called Warmbloods, this would include the Hanoverian, Holstein, Oldenburg, Dutch Warmblood and many others.
Czech Warmblood.
A Clydsdale is one breed of Draft horse. If you breed a draft horse ro a regular horse, you get what is commonly called a "warmblood", which are heavier than regular horses, but lighter than draft horses.
No it is not. The Dutch Warmblood was created by crossing Dutch drafts with Thoroughbreds and lighter riding horses to create a sporting type horse.
Yes the Holsteiner is a German breed of warmblood type horse.
Welsh Cob.
It's not a warmblood breed so a fairly rough diet is fine. Most live outdoors all year round.
Yes and No. There is a British Warmblood horse society but it's not a true breed. They register any horse of warmblood breeding. To be a true breed there must be a closed studbook of which only Trakehner warmbloods have.
The Czech Warmblood.
The Kladruber (warmblood)
Mainly European warmblood types. But I prefer Thoroughbreds myself, or a good Anglo-Arabian, or Irish bred horse.
They can be either or, depending on the actual breed.
There is never a magic number but Arabs are a breed that matures slowly and can still grow at 5 years. When training these horses you have to remember that and not to push him too hard. They are also a very sensitive breed and smart. Athough I have never trained a full Arab I doubt these horses will respond to a heavy hand. With this breed your better off to use your brain.
