I've probably treated 600 to 800 pot tox and while most could have freaked out for a while and then chilled for a few hours without medical attention, there was one 80vlb lab who ate enough butter to actually put himself in a coma for 4 days. That dog would have died without iv fluids, and life support..... Trip to the vet might cost a couple bucks but is better safe than sorry. Like you said, just don't let them get in your stash in the first place.
