As a non-pet owner, you don't really think too much about how the heat effects animals until you read/hear about it, or someone reminds you. On Thursday, someone rang Triple M while I was on the way to work and said not to walk your dogs today, and I just figured it's better to keep them inside - where it's cooler, until they made a comment about how dogs don't have shoes. I'd never have thought about blisters on dog's paws, but I guess its as likely to happen to them as it is to us when the sidewalk's so hot.
