I called the vet--not in (of course). They'll have someone call me. They said I could double the dose, but I don't think that would help unless he was compeletly out--and there's no way I want to do that. He's never been as bad for strangers and so maybe a groomer could handle him? I hate the whole idea of drugging him, he's old, has a heart murmur and elevated liver enzymes! I don't know what to do.... We are leaving tomorrow for a short camping trip in the RV and I can't bathe my stinky dog!
