The dr's office said it would have to be engorged for around 48 hours so it's probably okay. To err on the side of caution, I'm going in at 3. At most, I'll be out a few $ but at least, I'll get info on what to do next time.
As for Buddy, it was a wake-up call for us to get the Lyme shots done. We're leery of extra vaccinations, but it's too prevalent here to take the chance.
Thanks so much for the info & encouragement.
