Tony, what would work best for you is a fan motor application for a commercial kitchen dishwasher hood or grease exhaust. Both use a sealed motor with heat sinks and are designed to withstand high temperatures. Grainger has a great selection of the Dayton brand fans. Check into Greenheck as well. PM me on the specifics of your kennel application and I might have a better suggestion for you.
