Both animals and people can overdose on opioids, like fentanyl or heroine. Dogs — especially those on police K9 units — are the animals most at risk, since they explore their environment by sniffing and licking.
Affected dogs become lethargic and weak, then collapse and develop rapid, shallow breathing. At high doses, respiratory depression can quickly become fatal.
Once a dog has collapsed, administration of naloxone can reverse the effects of opioids within minutes. Narcan, the spray formulation, can be applied inside a dog’s nostrils. It’s harmless — even in the absence of an overdose — and can be accessed without a prescription at many retail pharmacies.
Narcan may have to be given more than once. And remember — any animal exposed to opioids should see a veterinarian immediately.
