We're always being told to make sure we have a healthy heart, but what about our dogs? From 30th January, The 2011 Mobile Dog Heart Health Tour kicks off and is heading to Miami Beach for an afternoon of free heart health examinations at Flamingo Dog Park. From 1 to 5 p.m. on Sunday certified veterinary cardiologists will perform on-site heart screenings in a soundproof medical unit, as well as educate owners about canine heart disease.
