(Dasher is sitting quietly with his tail between his legs, shaking.)
Vet Tech: "Does he bite?"
Me: "No."
Vet Tech: "Okay, I'm going to put a muzzle on him. He looks like a fear biter."
The vet tech applies the muzzle with no resistance from Dasher. He then draws blood and administers two shots. Not a peep from Dasher. No raised hair. No snarling. No growling. No whining. No crying. No movement beyond shaking.
He is not a fear biter. Do you know what his fear response was? He pooped on the vet tech.
