The answer isn't curt but the distinctive feature is strongly developed hunting instinct. By reference on this instinct the trainers train hounds physically and mentally. While training, the trainers bound engagement with other people and animals. They are taught guard, service and patrol skills. Depending on the particular area different dogs breeds adapted to different kinds of hunting have been formed. By its specifics all breeds of dogs can be divided into several groups: earth dog, husky, hound, pointing dog, greyhound and spaniel. If you want to go hunting and want to have a hound at first contact the society of hunters. It works on registration of all pedigree dogs. The selection is provided among one of the best in dog shows and dog competitions. In a society of hunters the crossing of the best species are made. If you contact the society they will give the addresses and phone numbers where you can ask and buy a puppy with all documents and pedigree. Available documents guarantee the quality of hunting skills of the dog. Another one main question is dog's care. It consists of feeding and skin care. Commercial feeds and homemade food is allowed. The main thing is that the food is fresh, various and complies the square. If your dog doesn't eat everything, take the rest of the feed and give it less food next time. Taking care of hair, comb it once a week with a metal brush. During the shedding, twice a year comb old hair intense. Bathe it when it's necessary. From spring to autumn watch for lice uprise. In such case, use special shampoo, drops at the withers and dog-collar. All these things you will find in pet stores. Vaccination and vermicidal procedures are necessary for hounds. Also take care of external ears and cut nails.
In the end I want to say that hounds should lead mobile mode of life, regular exercises strengthen the muscles and stop the process of obesity.
