My 2 1/2 year old son loved the book from the minute I brought it home from the library. No matter which other books I take out to read, he asks for this one instead. What attracted me was the illustrations have a "Richard Scarry" feel to them. So they are three gentle looking animals that are firefighters and save a dog in a fire. It's a fairly quick read, good for those nights where everyone is a little more tired than usual, and it rhymes. I'm here buying a copy now since the library book has to be returned in another week and I know I'll get the request for it. At the end, it has the back page where they explain in more detail different things a fire fighter uses like helmet, air mask, etc.
