brandimom Posted April 18, 2009 Share Posted April 18, 2009 I also have another sighthound, an afghan, that was on a high dosage of Soloxine .6 mg, male, wt 73 lbs. Since consulting with Dr. Dodds the dosage has been cut in half one week ago. In two weeks I will take him in again for another T4 test and it will be sent to Dr. Dodds for interpretation. Last month he was diagnosed with a slight heart murmur (did ultrasound with a cardiologist). Holistic vet said it may have caused an irregular heart beat but did not know if it caused a heart murmur. Any thoughts? This is one of the reasons I switched vets. Wish I had consulted with Dr. Dodds when the western vet suggested .6 mg. Quote Link to comment Share on other sites More sharing options...

Brindles Posted April 18, 2009 Share Posted April 18, 2009 I could see it causing an increased heart rate, but not an irregular heart rate or murmur.

RobinM Posted April 19, 2009 Share Posted April 19, 2009 Chloe weighs 70 pounds and is on .5 mg 2x a day. It doesn't seem like a high dose. I have never heard of it causing a murmer, but wait to see what the doc says.

Batmom Posted April 19, 2009 Share Posted April 19, 2009 It can cause high heart rate or irregular rate. But too low a dose -- that is, if dog is still hypothyroid even if medicated -- can also cause an irregular rate. Arrgh, eh? Hope you can get to the bottom of things.

seeh2o Posted April 19, 2009 Share Posted April 19, 2009 Carl weighs about 72 - 75lbs and is on a .7mg dose each day. I give him half a .7 tab in the morning when we get up, then the other half tab an hour before dinner. This was per Jean Dodds. Was your dog on .6mg 2 times a day? That would seem like a lot to me. Like Claudia said, I'd send her an email and ask.

VinnieAndRexsMom Posted April 19, 2009 Share Posted April 19, 2009 When thyroid meds have been too high, my heart was racing. Too low and I feel like I have a fat butterfly in my throat and I am confused and sluggish. Red was on a high dose (.8) for quite awhile because he was hypothyroid with all the symptoms. He had never been treated by his other family. After he leveled out, we cut it back a little at a time. You don't say what the levels tested at on the high dosage. Vinnie had a slight murmur because he did. He lived a long and normal life with his murmur, and only one vet ever heard it out of the four vets he saw.

brandimom Posted April 19, 2009 Author Share Posted April 19, 2009 You probably already know this but email Jean, you know she'll get back to you right away no matter where she is. I have never heard of it causing a murmur Jean normally gets back to me the same day and I did email her two days ago asking the same question. Have not heard back from her yet. I am glad you have not heard of it causing a murmur. Chloe weighs 70 pounds and is on .5 mg 2x a day. It doesn't seem like a high dose. I have never heard of it causing a murmer, but wait to see what the doc says. Do you mind sending me a PM with your email address. I would like to share with you an email I got from Dr. Dodds about a week ago which made me think the .6 mg. was too high. Thanks. Carl weighs about 72 - 75lbs and is on a .7mg dose each day. I give him half a .7 tab in the morning when we get up, then the other half tab an hour before dinner. This was per Jean Dodds. Was your dog on .6mg 2 times a day? That would seem like a lot to me.

Guest Greytluv Posted April 19, 2009 Share Posted April 19, 2009 Three of my dogs are on .3 2x a day. I've never heard of a Greyhound being on such a high dose of Soloxine .7 or .6 All my dogs are from Hemopet. I don't know anything about the murmur Quote Link to comment Share on other sites More sharing options...
Chicocat Posted April 19, 2009 Share Posted April 19, 2009 The dosage is based on how low the thyroid readings are and their weight. My girls (all in the 60 # range) are on .6 mg Soloxine. Now that their thyroid readings are stabilized they have been cut back to .6 once per day. Soloxine stays in the system for 24 hours.

brandimom Posted April 19, 2009 Author Share Posted April 19, 2009 Thanks for all the imput. I heard back from Dr. Dodds today and she said a high dosage can cause an irregular heart beat. As someone mentioned in their reply I forgot to give you the result of his last T4. It was 3.3. Quote Link to comment Share on other sites More sharing options...
FosterFlunker Posted April 19, 2009 Share Posted April 19, 2009 Star used to be on .8 Thyrotabs 2 times a day. When I changed vets he tested him and cut the dose to .5 twice a day.

VinnieAndRexsMom Posted April 19, 2009 Share Posted April 19, 2009 Yes, .8 twice a day for Red, too, until he began to test high. Then we lowered it. 3.3 and what is the range? Lab ranges vary.

Guest BarneysMom Posted April 20, 2009 Share Posted April 20, 2009 Barney (about 83 lbs) is on 0.8 mg Soloxine twice a day. He was just diagnosed with hypothyroidism in February though. How long do you usually wait before retesting? Is there a good way of feeling a grey's heartbeat yourself? Patty Quote Link to comment Share on other sites More sharing options...
FosterFlunker Posted April 20, 2009 Share Posted April 20, 2009 My vet after diagnosis said retest in 3 months and then every 6 months. Now mine tests once a year. Quote Make a fast friend adopt a greyhound Link to comment Share on other sites More sharing options...

Batmom Posted April 20, 2009 Share Posted April 20, 2009 Euthyroid sick is when the pup tests as hypothyroid when he doesn't have true thyroidal illness but rather a low thyroid reading due to some other illness. Lots of things -- tick disease, injury, infection, plain old stress -- can cause a low thyroid reading when the dog isn't hypothyroid and doesn't need supplementation. A comprehensive thyroid profile can usually detect the difference.
