Answer by  Badgzara (95)

If you notice that your dog has an abnormal rapid heart beat consult a vet as soon as possible. However, since there are many reasons... one reason could be food. Depending on what your dog has had access too. One food that people generally don't realize is deadly is chocolate. Chocolate can cause seizures, rapid heartbeat and even death.
