We always assumed our dog Sammy's singing with the church bells was an enjoyable experience for him - he'd leg it out to the garden as soon as the first chime went up, sit on the top step and howl away. If the front door was shut, he'd become agitated and scratch at it, and come and get us so that we'd open it for him. I was always wothwhile having guests around on a Tuesday evening to witness his performance.
