Last week, Irvine police officers gave the overdose-reversing drug naloxone to a pit bull puppy that they believed might have been exposed to fentanyl.
Unsure of the specific pharmacokinetics behind it but dogs take about 3x mcg per kg dosing compared to humans. A lethal dose of fentanyl for humans is 100-200 micrograms which would theoretically translate to about 600mcg lethal dosage for dogs. Considerably larger than a humans tolerance but still only a few granules of powder would be lethal
