The Knoxville Chamber of Commerce is searching for 50 artists to create special sculptures — of dogs. Knoxville Chamber of Commerce Director Pat Boyle says the dog sculptures will be displayed throughout Knoxville this spring, then auctioned off in late May to raise money for new fire equipment. This past summer, three-hundred cow sculptures were on display in downtown Chicago, the cows were auctioned off for charity. That’s where Boyle got the idea for Knoxville’s dog pack. Boyle hopes the auction and dog-related events — like a dog-a-thon walk — will raise 10-thousand dollars to buy a “thermal imaging camera” for Knoxville’s fire department. It’s an infra-red camera which pinpoints people in a building. Boyle has suggestions for doggie sculptures, including top dog, under dog and, of course, news hound.
