Yep. You gotta watch out for that kind of critter. "Wagging tails" don't always mean mans best friend. Or womans, for that matter.Once our neighbor had this dog that was always barking and acting mean. Time went by and he seemed to change.
Time went by and it got to where he wagged his tail acted friendly towards me. So one day I think I'll pet that dog since he knows me and now is friendly.
HE BIT ME!
After that when he was wagging and being so friendly, I knew it was because he was talking trash and planning to get me again.
