Can you please tell me what the number should be for thyroid. My 3yr. old female German Shepherd is on ThyroTab pills and I have been told two different numbers it should be at. First one said her blood work came back at 33 and that's good, not to be lower than 30. Then I moved and just had her blood work done after it's been 8 months and they so it's 22 and that's good.But I've noticed she is scratching more and flaky skin again. Can you please let me know what the numbers should be. Thanks for your time. I'm confused at what number is better.
The normal values for a T4 are between 1.0 and 4.0. vetcare
