My Dog Acts Dizzy Then His Rear Legs Collapse. He Twitches And Jerks Then Recovers Quickly. Happens Often. He Has Heart Issues. What Can I Do?
It sounds like your dog may have EIC (Exercise Induced Collapse). It's a genetic disorder. You should look up the particulars. It doesn't necessarily hurt them, but it can be dangerous if they collapse while doing something that could hurt them (swimming).
