It's a doggone chartbuster -- 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 (SPCA).
"On the other side of the scale, they just lie down and did nothing." The charity CD, priced at NZ$4.99 ($3.93), contained an instrumental and a vocal version of the song, but Kerridge said he did not know what kind of music dogs would hear.
"Never having heard it myself, I don't know what they'll hear and of course I don't know how dogs hear music," he said.
Kerridge added dogs in Australia and the United States could soon have a listen.
Around NZ$22,000 ($17,300) has been raised by the disc's sale.
