We have found that most dogs react very well to THC, both physically and mentally.  They generally have a good tolerance for overdose but don't really need much for a good effect.  As with people, it' a good idea to wait at least two hours to decide if you have had enough of an edible, and with dogs you can usually tell from their behavior.  If they still look miserable, probably not enough - happy and relaxed maybe even a little frisky is probably about right.  Overdoses generally look like your buddy walking wobbly, having trouble standing and on rare occasions vomiting or urination.  Extreme overdoses usually require dosing many times higher than the recommendation.   Please note: While Hyde was an amazing dog; he wasn't an actual doctor 'cuz all the "real" medical schools have rules barring dogs from attending...no matter how brilliant they are.  That being said, Dr. Hyde benefitted from cannabis for most of his life and enjoyed sharing with his friends in need so  he knew what he was barking about.  Dr. Hyde would like you to know that this product and the statements made on it have not been evaluated by the FDA.  This product is not intended to diagnose, treat, cure or prevent any disease.
