The German Sheppard is a good dog, so is a Border Collie. For a less energetic dog, an Irish Setter and Labrador Retriever make good pets.
For the adventurous, there is the wolfy, or part wolf and dog, but many are fakes, the real ones will howl. Wolfy will raid your refrigerator, they are very smart and can learn to turn a doorknob, but not a dead bolt, so, you have to keep watch on them. They are shy around strange humans, thus not a good watch dog, but they will attack dogs.
Another great on is the
Catahoula hound, these dogs are very aggressive, more than GS is my opinion. These dogs like to hunt and run down animals, sometimes strangers!
One of the funniest dog is the
Komodor, this dog may look funny, but do not laugh at him, as he is both dominant and sensitive!
Clearly, I like big dogs, not toy lap dogs and for cats, they are best outside catching mice.
