Schirmer Tear Test

The Schirmer Tear Test: is used to measure the amount of tears your dog’s eye is producing.
This involves putting a special strip of litmus paper, which is marked with a measuring scale, under the bottom eyelid and leaving it there for 60 seconds. The tears are absorbed by the paper and the line the tears reach on the measuring scale indicates whether or not your dog is producing enough tears. A normal reading would be at least 15mm in one minute.
