    Hello all. My name is Dan and I'm new here. My dog Bella, a 10 year old female sheltie, has a serious problem with her T4 level.

    About two years ago Bella started to lose her undercoat. I suspected a thyroid problem. Brought her to the Vet. He did the T4 test and sure enough, Bella's level wasn't even measurable.

    So we started her on Thyrotabs .3mg/twice a day. Her T4 level came up to .7, still low, but her hair came back and she was at the recommended dosage for her weight (26 pounds).

    Bella has been tested annually and her T4 remained at .7 until October of 2017. I noticed her hair started falling out again. Brought her in for testing and sure enough, her T4 was zero...or undetectable.

    Vet increased Bella's Thyrotabs to .6mg/twice daily. Twice the recommended dosage for her weight! Her hair stopped falling out. Re-tested her T4 in January. Still undetectable. So we did a full thyroid panel on her last week (February 7, 2018). We should get those results this Wednesday (14th).

    I should mention that Bella has been taking daily metronidazole several years for IBS. The Vet assures me this would not be a factor in her Hypothyroidism.

    So, I'm asking the forum here for any/all ideas. I'm at my wits end. The Vet also said it's the oddest thing he's ever encountered.

    Other than the hair loss, Bella's weight and energy are normal. She does seem a big aggressive at times.

    Any thoughts would be appreciated.

    Thank you,
    Dan

    Welcome to the forums, Dan. I'm sorry to hear about Bella's thyroid problems. Thyroid issues seem to be fairly common in Shelties. It certainly sounds like you're on top of it with testing, etc. though. I wish I could be more help but the only other thing I can think of that can account for coat change and hair loss is Cushings. Has she been tested for that? If not, you may want to consider it.

    I've had dogs with IBD as well, but I've never heard of daily metronidazole for maintenance. Flagyl is such a strong drug that I've only heard of it used on an as-needed basis. Is Bella's case that bad? I found careful diet can help a great deal so the dog isn't on meds all the time. Just a thought. But I do agree that it's not likely to have a correlation to her coat issues, although I'm not a vet and don't know for sure.

    I hope you can find some answers. Several of our members have experience with thryoid issues and may have more information. Please keep us posted!

    Welcome Dan. I am so sorry about Bella's thyroid problems! Over the years many of my Shelties have encountered thyroid problems! You are certainly doing the right thing by getting her tested frequently! .6 twice a day seems really high.
    Have you seen a specialist instead of your regular vet?
    I have no other information to offer but I know others who are more experienced can give you advice.
    Good luck and keep us posted!

    Hi Ann,

    Thanks for the reply. Yes, Bella is a mystery. Cushings has been floated out there as a possibility, but my vet insists I would know something is up because Bella would be drinking a ton of water (and urinating a lot). She's not.

    After sudden onset of diarrhea three years ago, Bella has been on a daily dose of 50mg Metronidazole for what the Vet thinks is IBS. Her diet is strictly Hill's Science Diet WD. She will not tolerate any other food. I do put some cooked chicken breast chunks in there to help get her more protein. Without this combination of Metronidazole and WD food, she has terrible Diarrhea and/or Vomiting.

    Bella's hypothyroidism is the biggest mystery of all. Other than hair loss, she has no other common symptoms. Her weight is perfect, her activity level is normal.

    I just wish we could get her T4 to the proper level. Part of me believes that her IBS is preventing full absorption of the Thyrotab supplement.

    We may know more with her full Thyroid panel comes back on Wed.

    ~Dan

    Many vets are generalists. I was thinking of a clinic that specializes in thyroid, or maybe Michigan State University here where I live or a pet referral clinic! Just a thought.

    Interestingly, Bella's blood work for her thyroid panel was sent to Michigan State! Hopefully we get the results and possible answers in the next day or two.

    That is quite possible!
