DNA evidence has established that Shar Pei dogs are among the oldest dog breeds in the world. The breed has survived all manner of hardships. Originating in the Guangdong Province of China, Shar Pei dogs were originally bred for dog fighting, as their loose skin and small ears make it difficult for other dogs to bite them in fights.
Shar Pei problem behaviors are few, although many people mistakenly believe the dogs have a difficult personality, perhaps because of their dog-fighting origins and because of the myth that the Shar Pei descended from the Chow Chow, which can be a difficult and temperamental breed.
Rottweilers have received a bad rap over the years, to the extent that some cities make it illegal to own this breed of dog. The truth is that Rottweilers are usually not the problem at all. Instead it is the owner who does not know how to exercise proper Rottweiler training and socialization.
Chihuahua potty training is something that every owner seems to fear if they have not gone through this process before. While it seems that there isn't a lot that a little Chihuahua can mess up with the little amount that they can hold, many people fear the fact that they cannot hold their bladders for very long because of their size and that Chihuahua training will be very difficult. But while some of that may be true, there is no reason why this training period has to be a stressful time.
