Tantrum has run over 500 miles this season with most runs in the 15-20 mile range. Great attitude. Nice trotting dog but runs best in my opinion in a short harness. Is a bit distracted near front--runs best near back of the team at this time. He is a yearling and will no doubt settle in. Great eater. Decent keeper. Hasn't had any foot issues or injuries. Nice personality with lots of socialization. We are only selling because we have too many yearlings and can't keep up the training for all of them. $450-Sale pending
