8. American Pit Bull
American Pit Bulls were brought to the States to fight bulls and later used as mascots during World War I, as it was believed to capture American spirit and bravery. The war clearly had some karmic impact on the breed, as it is the #1 dog blamed for fatal dog bites. The breed requires extensive and serious training and can’t be left to its own devices, or it can easily snap. Even potty training will be quite a challenge with it, but if you succeed, you will raise a truly loyal and protective dog.
7. Siberian Husky
You can take a dog out of Siberia, but you can’t take Siberia out of the dog. Having this dog run around your household is basically like letting a wolf inside your home. These gorgeous dogs love attention and are famously good-tempered. But the problem here is that this dog loves to work — it was bred to survive in tough climates and was used for all sorts of tough tasks. You’ll need to provide enough exercises to your dog for it to run out of energy. Otherwise, it will find itself some tasks of its own, which will include ruining your house and causing chaos wherever it goes.
6. German Shepherd
German Shepherds are incredibly intelligent, and that may actually cause some serious problems if you decide to have that dog as a pet. Originally bred to herd sheep, German Shepherds feel much more at home while serving law enforcement rather than watching you read your morning paper. These dogs require a lot of training and activity, which includes a lot of socializing. Otherwise it can go a little overboard while protecting itself and your family from the outside world.
