This is where things get really obvious. If your dog begins seizing or going through fainting spells then you should take your dog to the vet immediately. When your dog begins to seize you should treat them the same way you would a human. Meaning, hold them steady but don’t restrain them because they can hurt themselves or you can hurt them from holding onto them too tightly. After the episode is over, take your dog to the nearest vet or emergency care and consult with the veterinarian on how to handle your dog during episodes and if there’s a medication your dog can take to prevent them in the future.
