it does take a fairly large amount of theobromine, about 100-150 mg to be toxic to a 15 lb dog. I'm going to guess a lindt truffle to be about 10 grams each which would be .044 grams of toxin.
The theobromine info I got off my "toxic to your dog" chart. I haven't done that math in a while but I hope it's right. I hope this could put you at ease until you hear from the vet. |
