Legs Has Dilated Cardiomyopathy


Recommended Posts

I know this has been covered a lot, but please can you guys refresh my mind about thyroid testing. My vet has not seen many greyhounds so we rely a lot on the info I get here. So what exactly should be tested and how do I know if he truly needs to be medicated?

I know hypothyroidism is over diagnosed in greyhounds but I am seeing many symptoms that seem to match up to thyroid. Legs is just the sweetest, bestest boy and it's breaking my heart that he is not completely healthy like he should be at only 7 years old! Thanks in advance :)

UPDATE
Legs test results came back low, but not much different than 2 years ago. I feel that b/c he's showing so many symptoms it is worth trying medicating. Does anyone know how long it should take to know if it's helping him?

Continued updates in this thread :)

I had these tests done locally: TT4, TT3, fT4ed, FT3, T4AA, T3AA, TSH, TgAA.

Here's a link to MSU for their premium canine thyroid panel. Check the box at the top for the endocrinologist's interpretation. MSU thyroid form.

I'm gonna sound stupid, I'm sure... what does Hawaii have to do with vet tests? If there's no lab, Legs' blood could still be sent to MSU? I know I can send blood from Canada down to the US.

I imagine it would be quite expensive to send it from Hawaii to Michigan.

 

It's good to have a full panel done. My problem with MSU's interpretations is that they have defined hypothyroidism out of existence for greyhounds, IMO. Even if the greyhound has so little hormone that they can't even measure it, they won't recommend supplementation unless the TSH is elevated AND there are antibodies present. As I've said elsewhere, TSH measures are not always accurate indicators, and not all hypothyroidism is autoimmune in origin (so of course there will not be antibodies). And I consider that kind of interpretational rigidity dangerous to the health of our dogs. But in all cases you have to start with a panel. You can send the results to MSU and Dr. Dodds, or whomever, for interpretation later if it seems warranted.

Ft4 by ED, TSH and antibody testing would give you a complete picture. Hindsight is always 20-20 - wish I known enough to insist on the antibody testing when we were trying to figure out what was wrong with Suze last year. Would have definitely answered the question of "hypothyroid or euthyroid sick syndrome" once we received the diagnosis of PLN.

Legs came to me on thyroid meds, but his old owners only had the very basic (T4?) test done, so we re-tested and I believe sent to MSU. But his being on meds skewed the test so I opted to stop medicating. This was over 2 years ago so I'm a little fuzzy on the details. I know Dr. Dodds recommended putting Riley on thyroid meds when he was dxed with LP but showed no other symptoms of a thyroid problem, so I am weary of sending anything to her.

 

I will print this thread out before I take Legs in next week. Thanks so much everyone for your help!!

Even if the greyhound has so little hormone that they can't even measure it,

 

That is simply the nature of the science. The amount of free T4 in a greyhound -- or any other organism -- is so small that even the best assays we have (equilibrium dialysis) may not find enough to measure according to the established +/- accuracy of the test. And that is entirely normal.

My endocrinologist would disagree with you. If my free T4 were undetectable, he'd be upping my meds. As it is, he ups them when it's low.

Took Legs to the vet this morning. She is sending his blood to MSU. Should take a couple of weeks before we get the results. She also did cold laser therapy on his skin lesions and put him on abx. If he thyroid comes back ok next step is a heart monitor test since he's been basically collapsing after any kind of exercise. I'm sooo hoping it's thyroid :goodluck

 

Thanks again everyone! I'll update when I know anything.

Poor Legs. I too hope it's his thyroid. You'll be happy sending it to MSU. Did she request the Endocrinologist interpretation?

I believe so. She also told me we have a new specialist on the island she is going to consult with, so that is good. That way the specialist can examine him in person if needed.

 

The cold laser seems to really have helped his sores! Now I just need to keep him from licking and re-opening them which will be a huge challenge :(

I sympathize with the challenge of the sores. Having tried everything, the best combination I have found for my Suze is a muzzle with a stool cup to keep her from licking them and treating by washing gently every day and putting a few drops of calendula on them. Suze has other health issues which I am sure is interfering with the healing process, so hopefully Legs will heal quickly. But you're right - licking is a challenge!

thanks Linda. I've thought of ordering him a muzzle, but I just hate to do that to my sweet boy unless absolutely necessary :( If we get the results back & there is no thyroid issue it may come to that. He's continued to lick and re-opened all his sores :( But thankfully the antibiotics seem to be agreeing with him (he has a sensitive tummy), so hopefully they will kick in soon.
