This news will be a amazing thing for dog lovers. who can't believe size of huge dogs. But its here. Yes, still some breeds of dog are unknown to most of the people but they are loved by many people. Those people will treat dogs like a family. Giant dog breeds are simply extra-large canines. Like any type of dog, giant dog breeds have their pros and cons. On the positive side, giant dogs are typically very gentle, affectionate and loyal. They tend not to need too much exercise and are not very difficult to train.
Potential negatives include a tendency to drool quite a lot and cost more in food and supplies.In addition, many large dogs are more prone to orthopedic problems or health issues like bloat.Perhaps the most unfortunate thing is that extra large dog breeds tend to have a shorter life span compared to the average canine (about 6-10 years compared to the 12-15 years most dogs live). However, those who adore these big beauties feel that it adds up to a small price to pay.
Typically weighing anywhere from 100 to 200 pounds, giant dogs need ample space in their homes for large dog beds and plenty of tail wagging space. When these big dogs are young and not fully trained, they may not know their size and strength. However, with age and proper training, they usually become gentle giants. While plenty of people prefer small dog breeds, many other people feel that giant dogs cannot be beat.

The Leonberger is a giant dog breed. The breed's name derives from the city of Leonberg in Baden-Württemberg, German. According to legend, the Leonberger was ostensibly bred as a 'symbolic dog' that would mimic the lion in the town crest. It is in the working group for dog shows such as crufts, but not at the world dog show.
This Mountain dog comes with a generous double coat; the Leonberger is a large, muscular, and elegant dog with balanced body type, medium temperament, and dramatic presence. The head is adorned with a striking black mask, and projects the breed's distinct expression of intelligence, pride, and kindliness. Remaining true to their early roots as a capable family and working dog (particularly water), the surprisingly agile Leonberger is sound and coordinated, with both strength in bearing and elegance in movement. A dimorphic breed, the Leonberger possesses either a strongly masculine or elegantly feminine form, making gender immediately discernible. When properly trained and socialized, the Leonberger is vigilant, loyal, and confident in all situations. Robust, adaptable, obedient, intelligent, playful, and kindly, the Leonberger is an appropriate family companion for modern living conditions
