As many of you may remember, I have a boxer (who thinks she's a basenji) named Zina. She had HOD and at last count had been to the breeders for a 'vacation' and to, at the time we thought, end her life there. She did bounce back and came back to me from her arthritis and various problems. She was still lethargic and showed no interest in life when she came back, although she looked a lot better. I had a blood panel done on her for thyroid a little bit back-about a month ago or three weeks. The vet said her thyroid levels were fine and wanted to try her on cyclosporine. Which she would be on for the rest of her life. I wanted to take her off everything, if I could, and he didn't want her that way. I did ask for the results of the panel and when I got them, I was sad to see, in my estimation, that they were low. I contacted Dr. Dodds and asked what she suggested. She also agreed that they were low and suboptimal. I asked Dr. Dodds what I should put her on. I did end up putting her on a dosage of soloxine and she has done fabulous. This dog did not want to go outside and was depressed. In the few weeks that she has been on the thyroid meds, she has become her old bouncy self that I have not seen since before last spring. She's running through the house again and jumping all over and playing. I will post a video of her this weekend so you can see that she is typical boxer like. I have also been able to start to decrease her Dexamethasone.
Vets are not always right. Take the time to look at your levels for testing yourself.
