I have two pit bulls! They get into so much trouble.
I have an American Bulldog, which is also a pit bull!
Nice! Do you know why they are so aggressive sometimes? Mine tore my couch to pieces. 
I'm not too entirely certain, but their remarkable aggressiveness makes them ideal for catch dogs, hunting dogs, and dogs to protect the home.
Wow interesting. Maybe I need to take mine into the woods more often.
Yeah, catching dogs are really superb animals. They're used to catch and herd big animals such as bears!
Really? I live in an area that has some bears. I don't want my dogs to go anywhere near them! Do you know how long people have had them as pets?
Archaeologists believe that humans have had dogs around for about 14,000 years or so. But there is evidence that it may have been much earlier than this.
