These three Basset hounds are singing a concerto along with their owner, who seems to be encouraging them as they get louder and louder.
The trio plus owner howl and yodel from their living room as they seem to be offering a tribute to some unknown thing.
Are they howling for the fun of it?
Are they practicing for the next episode of Star Search?
All we know is that you will be mesmerized by these forty seconds of harmonious howling by these three happy and cheerfully loud serenading pooches.
