He hasn't thrown up, that we are aware of, and he's eating and drinking like normal. Going to the toilet normal too (both ways) However he is a bit lethargic, but he's always been a lazy dog, and he seems to be limping but I can't tell which leg, he is also stiff. He seem's to have improved, but I didn't think it was chocolate until today, I found an empty bag of milk choc chips. He could have had upwards of 100g. I am really scared. Will he be okay?
