Below are some recent questions we've received regarding Schirmer Tear Test, including answers from our team.
What is the expected results of this test on a 8 week old puppy with normal tear production?
I would expect 15mm of wetting within 1 minute. Many dogs will produce a lot more than this, though small puppies tend to be slower.
How early can this test be used if you suspect dry eye in a puppy
The test can be done from any age. I am not sure how well you can interpret the results on puppies under about 12 weeks old, but it will measure tear flow in any age. Dry eye would be unusual in a puppy though, it is normally acquired in older dogs from about 6 years of age.
