I recently adopted a very sweet tiny chihuahua. We took little Agatha in for her second set of shots this morning. The assistant bragged on her after taking her away to weigh her that she was so sweet ... stayed right up against her cheek. TILL... she tried to take her temperature (from you know where) thereby Aggie snarled and snapped. The assistant tried to put a muzzle on her and couldn't accomplish it.. Aggie did let me put it on her as I told her she would be so pretty wearing it. Then she met her vet for the very first time with a green muzzle upon her puzzled face. *smile*
