A music single for dogs topped New Zealand charts

A song audible only to dogs has topped New Zealand record charts, and is looking to go global.

"A Very Silent Night", recorded at a frequency only dogs can hear, was so popular among owners it hit number one at Christmas, but has been receiving mixed responses from listeners.

"The most violent one was a dog that physically attacked the radio when it was played and went quite berserk and totally destroyed it," said Bob Kerridge, chief executive of animal welfare group, the Society for the Prevention of Cruelty to Animals.

"On the other side of the scale, they just lie down and did nothing." The charity CD, priced at $3.93, contained an instrumental and a vocal version of the song. Kerridge added dogs in Australia and the United States could soon have a listen.

Around $17,300 has been raised by the disc's sale. CREDIT: Reuters
