Since your pet is a curious creature and loves to play with everything in sight, they may end up playing with an electrical cord. Playing with this can result in an electrical shock and can trigger a seizure or stop the heart. Usually a clear cut sign that your pet has been shocked is a burned strip across the tongue called an "electrical bite." Even if your pet seems fine it can cause an erratic heartbeat or problems with breathing in a few days, it is crucial to have your pet checked out by a vet immediately.
