Thats not something to play with.  I'm on it my self and so was Rocky.  It goes by your test results.  You can over medicate a dog really easily.  If your questioning the does why not talk to the vet.  The dog probably need it for a long time.  It will take time to build up in the system just like it does in humans.  I' m on 3 grains of my medication that doesn't mean someone else my same weight would take the same amount. It would be based on the blood work which would tell you how low the thyroid function is and then the right does would be prescribed.  I really suggest you talk to the vet about this.

I agree with previous about dosage depending on bloodwork numbers.  Years ago my almost 12 year old developed the seasonal alopecia, so of course we went for thyroid testing.  Vet said she was borderline low and started her on low dose of soloxine, which didn't do anything for the alopecia.  Then her daughter had heats that were 13 mo. apart, so I decided to re-do the mother's test and also have daughter's sent to Dr. Jean Dodd's, who is known for her expertise in thyroid.  I spoke to Dr. Dodds, and she said that low normal was still normal and no medication was required, and the other was normal...that was just her cycle.   So neither required the medication.   You might suggest that your friend's vet contact her.  All vets know who she is, and her information is readily available by internet search.  Good luck!
