Hi. I'm Dr. Gotthelf. I have been a vet for 33 years and I would like to use my experience to help you with your pet's medical problem.
Sevin dust is not terribly toxic to dogs, depending on how much the dog ingested. Atropine sulfate is the antidote to Sevin. It can be repeated every 8 hours when there are symptoms present, like salivation, vomiting, and muscle tremors.
