Dogs know how to swim, but there's a lot more to being in the water than that, according to Alphadog Training Academy's Abby Bird. Bird led a session on the May River at Brighton Beach on June 6, 2014, classes she offers every Friday through mid-August at numerous locations in Bluffton and Hilton Head Island at area rivers, ponds and swimming pools. Bird teaches dogs how to safely get out of pools, retrieve toys, dock dive and swim with their owners. The classes are free, with the exception of dock diving, which is $10. Registration is required.
