Hi Everyone, My name is Amanda and Jax is my 3 year old intact male sheltie. I've been reading the forums for awhile but this is my first post. I had Jax's thyroid levels tested last week, just as a routine check, he has no symptoms at all. Everything was normal except for his Thyroglobulin Autoantibodies. Here are his results: Total T4 - 2.6 Adult Range 0.8-3.5 Free T4(ED) - 28 Adult Range 8-40 TSH - 0.09 Adult Range 0-0.60 Thyroglobulin Autoantibodies - 137% Adult Range:<10% = Negative 10%-25% Equivocal >25% Positive I sent his test info off to Dr. Jean Dodds for a consultation and she suggests medicating him immediately. I also have others telling me he doesn't need to be medicated yet, just monitored as his other levels are normal and he has no clinical symptoms. I just want to do the right thing for him, and I'm really confused about what that is. I don't want to unnecessarily medicate him, but I also don't want to wait until he's really sick before I do anything. He will not be bred, that was never even on the table, but he is intact because I feel that he's healthier that way. Do any of you have any advice or experience with this issue? Thanks for any advice you can offer!!
