Dylan, Dixie and I were in the back yard. I noticed she wouldn't stop barking. I figured it was at the neighbors. Which isn't unusual. She will, usually, take a pause if I shush her but she just kept on barking and I realized it sounded different. I know that sound because she does it when she finds something scary. So I hurried over and found out what I think to be a copperhead. She was barking at it while only 1-2 inches from it. Thank God it didn't strike her.
