My dog accidentally ingested 20 mg sildenafil (prescription is for my other dog). She is 55lbs. Seems fine at 30 minutes after ingestion. What should I watch for?

Hello. This was a very low dose for your dog to ingest, plus a one time accidental dosing would not be worrisome either. You have nothing to worry about & should see absolutely nothing in your pet. Thanks for using Petco Pet Education Center, formerly Petcoach.
