Karen,

When I take Rocky to the vets,
I either muzzle him, in the waiting room,
or when we get to our room.
Even a muzzle can make a dog more nervouse,
so I tend to put it on in the room before the
vet comes in. (unless the waiting room is crowded.)

Poor Logan must have had some bad experience and
is very scared. Rocky is scared of the vet since
the day he got neutered their. In my opinion
a small dose of tranqulizer might make her a bit
more relaxed but she still might have to be muzzled.

I think they need to be very gentle with Logan so
she can learn to trust them.
JMHO
