Has anybody ever had a dog refuse a contact at a trial that had a drastically different surface texture than the one they are used to practicing on? My dog refused every contact at a trial just a few days ago. He'd get on then jump right off and then refuse to get on again. JWW was excellent so I don't think it's a foot or leg problem. It was just so strange! Contacts are a non-issue in practice so it caught me totally off guard.
