I have two boxers and a pit, between the three of them, over the last few months they've busted into my room and eaten nolvadex, winny, flax seed oil, multi-vitamins, tar from the new roof, cat shit, dog shit, ear plugs, a big candle, three pillows, four cds, and possibly a vicodin. I think dogs' stomachs are made from steel bro. But, 150mgs is a lot, so just keep an eye on him.
