My vet's practice has 4 vets, all with different personalities. Some dogs love one vet, but run when they see another. Occasionally, depending on the procedure to be performed and the dog's temperament, the vet is more comfortable if the dog is lightly muzzled - yes, even the sweetest dogs in the world! I suggest you try and find a new vet - your profile just reads Ontario. My primary vet is excellent - but located in Toronto.
