Well yeah, it's rat poison. If it was intended to kill dogs, they'ed call it dog poison.

That a poison has some minimum dosage or can potentially be prevented from causing harm with proper intervention is irrelevant. The same could be said for cyanide. The fact is that there is some dosage that can cause serious harm without proper intervention.

My point is that rat poison is a serious risk to dogs. Technically anything that chemically causes undesired side effects is a poison, but colloquially we tend to distinguish between things that are dangerous and things that are merely unpleasant. Rat poison is firmly in the first category, cannabis is in the second.
