Your comments are dead on accurate.
My neighbor’s dog committed suicide. She always stayed close to home until she started having health problems.
Then she started wandering all over and neighbors kept bringing her home. On her last hour I saw her wandering the dark country lane as I headed to town, and I tried in vain to coax her into my ride. I gave up and continued on my way.
Next day I get word the dog was hit on the rural route about a half mile from where I saw her.
Purty crazy I know, but sure looks like suicide to me.
