Thyroid Just A Little Low For Jenna


Recommended Posts

just had bloodwork done on jordan and jenna. had noticed that jenna's bare spot on her tail has gotten bigger around and longer. so had vet run thyroid test. jenna came back .9. went to suzanne stacks site and she show 1.0 being on the low side of low. i just want to verify before i put jenna on thyroid meds. i do NOT like to dose my kids unnecessarily - but i also know the consequences of not treating a low thyroid condition in greys; thanks for any and all input.

If you'll look at Stack's article again, you'll see that she cites a study that shows .7 as the bottom of a normal T4 range for greyhounds. As the article says, it's not just the T4 level, it's the relationship of T4 to several other hormones. There's a helpful chart toward the end of the article that shows the levels of three different greyhounds and what the levels might mean. Did you have the full thyroid panel run (more expensive), or just the T4?

 

I had a hound who was losing fur and her T4 was tested at .7. Then I read GreyTalk :) and had a full panel run by Michigan State (I think), which at least at that time was the premiere place for thyroid testing. The results came back with a specialist's opinion. My regular vet shook his head, but said he had to follow the experts and .7 was the normal level for this hound.

You can not diagnose hypothyroidism in a greyhound by a T4 only. Greyhounds T4's run about half of "other breeds". You need to run a full panel (MSU is the gold standard in the industry) or minimally a Free T4/cTSH (although I find gh's FT4's typically run on the low side too). If your hound is hypoT the cTSH should return above the reference range.

Yes, sounds like stud tail to me. Absolutely what tbhounds said. No supplementation without a thyroid panel, preferably from MSU. When your vet orders it,you might ask him to add on the interpretation. It's only a small fee to add it on and then you'll have a second opinion on whether to treat based on the results. The interpretation can always be ordered after the fact as well.

I just had Buck tested, and he was .6 My vet immediately wanted to do Soloxine, and I said, "No so fast!" and told her about the normal vs. Greyhound normal with thyroid, and so Saturday I take him in for another blood draw so they can run a complete thyroid panel.

I was wondering the same thing, Chad.

Carolina's T4's have continued to sneak down the last two years. She hasn't been acting any different so I haven't pushed for further testing.

I don't think we need a picture because "stud tail" is very, very common. It's a bare spot on the tail about 1/3 of the way down from the top. Not sure why it's called stud tail, but all breeds of dogs can get it, it's harmless, and treating a dog with Soloxine for it would be crazy.

Just wondering what is the "consequences for not treating low thyroid in greyhounds"?

 

I was wondering what Karen meant by this as well. Hypothyroidism is pretty rare in greyhounds and is more often misdiagnosed. Most of the greyhounds I've seen who were on thyroid supplement really didn't need to be, and I've taken more greyhounds off thyroid meds than started on it. Here's a good article:

And here's a previous thread about stud tail with a couple photos:
