There's litttle risk from that drug even in excess for an 85 lb dog. You're likely to see its laxative effects within 6-10 hours and cramping, diarrhea, vomiting and, potentially, fluid and electrolyte imbalances can occur with egregious overdoses. A usual dose for an 85 lb dog would be three of the 5 mg tablets. It's minimally absorbed after oral administration and so systemic toxicity isn't an issue. Monitor him, please, and have replacement fluids and electrolytes given if fluid loss is excessive from either end of him (unlikely). Please respond with further questions or concerns if you wish.
