Hello, and thanks for using PetCoach. If it was just a couple licks, then the dose of caffeine Niko got would be pretty small and I wouldn’t induce intervene. If he drank a more significant amount then I recommend contacting Pet Poison Helpline to better quantify and assess how much caffeine he actually consumed. From your description it sounds like a pretty small amount - but if you perceive it was more than a couple licks, it’s worth getting guidance from the toxicology experts.
There is a $65 fee to start a consultation with Pet Poison, but that’s far less than you’d spend rushing him in to an emergency vet, and they very likely may advise you that his caffeine exposure was small enough not to be of concern. Since the cold brew is liquid, it may be too late to get out of his system even if you induced vomiting, so the question at this point is likely whether you should watch for development of symptoms or whether the exposure is high enough to warrant preemptive hospitalization. I do not suspect Niko’s exposure was that high, but we’d need more info on exactly how much he consumed.
Here’s the info for Pet Poison Helpline if you decide to call:
