Yes this stuff is really dangerous and it needs a warning label I have had a few dogs in my life and gave this stuff to them thank god it didn't kill them I had no clue how bad this stuff was until that day, I talked to the vet after he did a neoscopy and he told me even if I had got him there there would have not much he could have done either this whole ordeal took all of three minutes and I at that point had no idea what was wrong I thought he had been poisoned till the day I die I will never forget how he cried and the helpless feeling I had so please tell everyone you know about these things.
