Wow, Squish, I know you work in a specialty hosp, but so do I, and I think GPs are getting an unnecessarily harsh rap on this thread. What we (veterinarians) say is not always what clients perceive, and we give clients A LOT of information when they come in for a first seizure, so it may well be a case of what the vet said is not what the client heard/comprehended.
Phenobarbital remains a widely used, very safe drug. It is economical, and it has saved the lives of probably countless dogs whose owners cannot afford more expensive drugs or can’t do TID administration.
And my point in the previous post was NOT about boarding or grooming facilities accepting rabies titers, my point was that any health department is not going to accept a titer when your unvaccinated dog bites someone. There is no established “safe” value for the titer.
