Tyke ate an extra heart worm pill before accidentally...he was fine so you shouldnt have to worry =).
It was when he found one of my Midols that kind of concerned me

We were driving and I...uh...needed a midol for obvious reasons and I had it in my hand with a glass of water. We turned real sharp and I reached over to hold onto to Tyke and dropped the pill. He was fine (we got him to a vet) and well I guess he didn't have cramps later that night lol
