Kipper our 5 month old ACD puppy is having SEIZURES!

A month ago I applyed the first of the three month Hartz Ultra Guard for small dogs and puppies. No issues. Then a week ago I applied the 2nd treatment…now today at 1:00 he had a seizure, then another at 5:30, then again at 9:00 and just now another 1:16AM. I JUST a year ago put down my 24 year old English setter and can’t bare to think I’m going to lose Kipper already! And to think I did this to him! Now we live out in the middle of NO WHERE and I can’t get him to a vet until Monday! Will giving him a dawn bath help at all at this point???
