Blazer's Taxi — Una Belle Townsend

In Una Belle Townsend's latest children's book, Blazer's Taxi, an unusual friendship exists between a Clydesdale and a mini-horse.  When Doug Sauter buys the Clydesdale, whose name is Blazer, he can't get the horse onto the trailer until Taxi, his very small friend, is loaded first.  After all, the two horses ran and played together in the pasture and had a marvelous time.  Blazer wasn't going anywhere without his friend, so Taxi remained with his buddy, and Doug ended up with two horses, the big one and the tiny one.  Blazer eventually became the mascot of the Oklahoma City Blazers hockey team, which Doug Sauter coached.  The three of them traveled with the hockey team across America and Canada.
