The story I am about to relate is why we have to be wary about what we believe about certain dog breeds. I was talking to a woman and daughter. They explained that they had gotten two dogs who they were assured were a certain type of mix(don't remember the mix) Later the dogs became aggressive. The woman stated that was when she knew that the woman she had purchased the dogs from had lied and sold her a pit bull mix. I asked how she knew that the dogs were pit bull mixes and she said, 'because they became aggressive." I wonder how many people who have been bit by dogs simply assumed that the dog must have had certain breeds in them because those are the only breeds that they think will attack them.
