A Lab? I call BS
Labs are generally more mellow. A lot of pit bull owners do, unfortunately, get them due to their inbred aggressive traits (not all pit bulls, I know there are some happy pit owners here). A person who wants an aggressive dog can train any breed to do something like this.
Don’t be so quick on that one.
This is the high desert.
The article say more like a lab. I can tell you from working with a shelter, if a dog comes in that is black with long ears they always say the breed is Lab mix to make it more adoptable.
