My 140lb Dane got his pill bottle out of our cupboard. I am unsure how many, if any, he may have eaten. I found the bottle chewed & open, it had about 4 pills left. I am ashamed to say, I do not know how many were in there, as I split the pills between 2 bottles. He doesn't usually eat them willingly-I always put them in bread with butter. He is only given 1 1/2 pill when needed. He does not take it on a regular basis. I find no evidence of vomit, and he seems to be fine. He went out to pee as normal & is resting beside me. We are doing a race tomorrow. Should I not have him run? what should I be watching for? I read vomiting is good so it gets the drug out before absorbing it, but he shows no signs of discomfort....
