Our dog, Harley spent all of July 4 barking. We were sitting on the patio and suddenly he would see some action on the lake (e.g. a boat, paddleboard, catamaran, kayak etc. passing) and he would rush downhill to the dock barking all the way. He would then run up and down the dock a few times and then run back up to the patio. Until the next boat passed (it seemed like 15 seconds later) and then he would repeat the process. He must have been exhausted by the end of the day – I know I was and I’m sure our neighbors were.
I guess it was all too much for him.
