The Butcher dog of Rottweil has become more famous than Germans ever dreamed of. The most popular dog of the nineties is a powerful, molosser-type dog, in black and tan. 
It is not a giant dog, the Rottweiler is a medium-large, compact dog, which stands out for its solid black coat with well defined tan colored marks. It is famous for its strength and agility, it stands at 61 cm; the female, 5 cm less. The body length is slightly above the height (9:10). The head is wide between the ears and medium lengthed; on a profile, the forehead moderately arched, well developed stop and well mark orbits. The eyes are medium sized, almond shaped, dark brown, with well adhering eyelids. The ears dropping, triangular, very separated and high implanted. The muzzle is wide at the base, narrowing with a well developed chin and wide, black nose. The correct closing is in scissor and complete 42 piece dentition is mandatory. Lower or upper prognathism and the lack of premolars and molars disqualifies from the show rink. The back is firm and leveled; the chest, wide and deep (approx. a 50 % of the dog’s height); the rump only slightly descending. The tail is docked short and close to the body, in countries where docking is forbidden, the tail is left natural. Strongly developed and straight limbs with a heavy bone structure, not closed; hinds in balance with the forequarters; good hind angulations. Built to trot, the Rottweiler should move confidently and balanced; cow like or open hocks should be discarded. The coat is comprised by external hair and internal fluff. The external hair is medium length, hard and tight; the internal fluff should not protrude from external hair.
WHO IS IT RIGHT FOR             
Never choose a Rottweiler because it is large. It is a large dog, no question, but its virtues should be its good nature, a set of good hips and its desire to please its owner. 
A well bred Rottweiler is a kind animal, family loving and a natural guardian. The temperament can vary: some are independent, reserved and not so kind, while others are extroverted and gregarious with everyone. It is a medium-large animal with incredible strength which needs to be trained and socialized properly to love people. The Rottweiler is an active and very agile dog for its size, able to run and jump easily. It is educated enough to live inside the house and happiest when with its people. Attack training is highly discouraged, since it over stimulates its already protective instinct due to which it would become uncontrollable. To a certain extent, every Rottweiler is aggressive and not apt for a shy or insecure owner.
The Rottweiler puppy should be extroverted and kind, not suspicious or shy. The female should be similar, and not overprotective, aggressive or nervous.
The weigh at birth varies between 340 and 520 g, although puppies from large litters can weigh less. At the beginning growth is relatively slow, but increases afterwards. After eight weeks the weigh should be between 7 and 7.5 kg. The buyer should avoid an excessively large specimen, so many times advertised, since they are more prone to bone problems, including hip dysplasia, as well as stomach torsion and other complications. The Rottweiler is already a large dog, and if it is senseless, it can even be harmful to seek for even larger specimens. The buyer should select carefully, insisting in health certificates and parent’s X – rays. Check puppy and parent’s movement, and obviously insist on a balanced temperament on both sides. Avoid timid puppies or proceeding from aggressive parents. We cannot stress the importance of socialization and training enough. Maturity is reached after two or three years.
Everyone is breeding Rottweiler nowadays, and you cannot afford the luxury of not being selective. Make sure that the parents and grandparents hold dysplasia free certificate. X – rays are not show dog matters: who wants a Rottweiler that will limp after two years and has to be put down after five?
The character and hip dysplasia are two of the largest concerns for Rottweiler breeders. The future owner should insist in breeders with proven character and early puppy socialization. The owner should continue socialization and enroll the puppy into a basic puppy school to help guarantee the Rottweiler’s good character. It is proven that the breed is very susceptible to parvovirus, and this has become a breeder concern. Other problems affecting the Rottweiler include entropion, retinal dysplasia, osteochondritis and pancreatic insufficiency; although its incidence is limited. Some breeders also inform alimentary complications and the owner is recommended to ask about it and following a diet program advised by the breeder. Care is minimal, although it requires plenty of training and exercise. Beware of heat strokes. The Rottweiler can live more than ten years, being heart disease, cancer and stomach torsion the main death causes.
