Topic: Dander

Question:My dog has been on thyroid meds for 6 wks, bloodwork was checked after one month and levels are good. He seems to be responding well, loosing some needed weight, is generally happier. When will the excessive dander stop?

Answer:That will take a few more weeks. Consider adding some Omega 3 fatty acids to his diet to help with the dander, like this product: https://www.1800petmeds.com/Welactin+Omega+3+Canine-prod11837.html

Topic: seizures or fainting episodes

Question:My pug was diagnosed in August with low thyroid and was put on Levothyroxine. Recently, she started having these episodes, we weren't sure if she was fainting or if it was a seizure. She acts totally fine after the episode has happened. We took her to our vet, he did an x-ray and everything looked good, he detected maybe a slight murmur. We had an ultrasound and EKG done at a different vet, there was a mild enlargement of the right ventricle didn't seem concerned. There was also a low grade electrical block so want to follow up with a 24 hour holter/monitor. We have been waiting to get to our vet, they haven't reviewed yet, which has been now almost a week. This morning she had another episode, this time to us, looked like a seizure. So we think that is what has been happening all along. I am bringing her to my vet tomorrow, hopefully. Looking at her bloodwork, the other vet also noticed her liver enzymes were elevated back in August, so recommend more blood work to be done. Do you think the seizures are related to the liver? Or do you think it is related to her heart?

Answer:That's impossible for me to really guess but, yes, repeating the blood work will tell you about the liver and the Holter monitor will probably tell you about the heart.

Topic: Supplements

Question:Are there supplements that I can give to help with excessive shedding? My girly is 8 1/2 and has been on .3 mg Levo twice a day for about 4 years. Her T4 is always high normal when I have it checked. She still has some of the classic 'puppy fur' of a hypo dog and it sheds like mad--Makes me think of a Persian cat every week when I groom her. She is also developing the characteristic rat tail as she ages.

Answer:This is a common question. Either fortunately or unfortunately, if they have no areas of hair loss, it usually just means they are really healthy and eat good, quality food, so not a lot can be specifically done about it. (Don't change to cheap food, lol) The best thing I can recommend is brushing them with the Furminator - it will help a little. Here is a link if you would like to read about it: https://www.1800petmeds.com/FURminator+deShedding+Tool+for+Dogs+-prod658143.html Fatty acids may help as well - here is a link to one such product: https://www.1800petmeds.com/Super+Pure+Omega+3+Bite+Sized+Chews-prod11379.html

Topic: Correct Dosage

Question:My pets dosage is 200MCG on her prescription bottle but, I don't see that as an available dosage on the website. What dosage is comparable to what I need to give her?

Answer:I don't know what medication you are referring to but most medication for hypothyroidism (that's the category you chose) is measured in mg = milligrams like this product: https://www.1800petmeds.com/Levothyroxine+Sodium+Tablets+%28Thyro+Tabs%29-prod12031.html

Topic: Meds not working

Question:Hi. I have an 8 yr old boxer who was diagnosed with hypothyroidism almost a year ago. Her symptoms were a low T4 reading of 0.4, free T4 of 11, excess shedding, acid reflux, throwing up food, loose stool, chronic UTI infections, chronic skin infections, anxiety and aggression, not wanting to be body handled. She's been on 0.8 mg of soloxine (split up and given twice a day). She also was given a supplement called "Thyro Complex" which contained thyroid and adrenal glandulars, kelp, and iodine. I also had been giving her digestive enzymes, probiotics, and changed to a higher quality food. She immediately began to lose weight quickly (she has always been the ideal/athletlic body type), suffered urinary incontinence, ravenous hunger and thirst, but her coat changed dramatically (in a good way) and her anxiety improved. I took her off the thyro complex because of the urinary symptoms and they stopped immediately but then her coat and digestive symptoms got much worse. Eventually I found her an herbal supplement called ¿Adrenal Calm¿ which immediately improved her anxiety, coat, and immune system (no UTIs or skin infections since!) with no urinary symptoms. For the first three months of the soloxine (January-March 2019) her T4 remain unchanged. In April of 2019 I then put her on 50 mg of trazodone twice a day for her anxiety and within 2 weeks her T4 shot up to 1.4 In June, T4 was at 2.5, and as of July 2019 it was 3.5. In October I weaned off of trazodone (it was making her aggressive and confident about it) and her T4, which we measured a week after her last dose of trazodone, dropped to 2.5 again. The vet seems to think that she should continue the soloxine but in my opinion the soloxine has not improved ANY of her symptoms! So I don¿t know if maybe she needs more soloxine, or has she been misdiagnosed??

Answer:If the Soloxine made her grow her hair back, she probably does need the Soloxine - possibly a lower dosage. A T-4 and TSH level run at the same time should tell you if she is hypothyroid.

Topic: thyroid testing

Question:Is T-4 enough?

Answer:A TSH with a T-4 is ideal. Here is a good article, written by another veterinarian, from a site that I trust, about hypothyroidism: https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4952004

Topic: Panting

Question:Is there anything that can relieve the panting my dog experiences frequently from his thyroid disease?

Answer:Have his thyroid levels checked - he may be taking a little bit too much of the supplement - that is the most common reason they will pant, but there are other reasons as well, so having your veterinarian check him out when they run those blood levels is ideal as well.

Topic: Adding Proanthozone

Question:Hi there, I recently received an email from 1800PetMeds with suggestions for supplements to go along with the levothyroxine that my 65lb dog takes. She has been taking Levo for about 4 years and is currently 12 years old. I ordered the Proanthozone because it looks like it may help some of the side effects of hypothyroidism she has such as joint pain (inflammation), hair loss and dry skin. We¿ve ruled out allergies at the vet. I just wanted to make sure the Proanthozone will be complimentary to the Levothyroxine and not work against it? I was confused because later in the email it says that HYPERthyroidism is treated with Proanthozone. And she¿s HYPO but recently having some changes. She¿s also taking cosequin & omega 3

Answer:It should be fine to give with the Levothyroxine BUT your question is a really good one because thyroid medication in particular changes the metabolism of various drugs, so I would feel better if you called and spoke directly to the manufacturer's veterinarian - they may want you to use a little lower dosage.

Question: Laboratory diluted blood sample for test results of CBC, total chemistry panel, T 3, T 4 and free T 4 due to inadequate specimen. No T S H testing completed. Results showed T 4 @ 0.5 and free T 4 at 7.9. Does blood dilution affect blood test results and w/o T S H testing don't really know if dog needs medication?

Answer:Ideally, I would submit another adequate sample, mainly to get a TSH to be 100% sure medication is needed.

Topic: Thyro Tabs dosage

Question:Is the dosage supposed to be given 1 hour before eating or 3 hours after eating Or Every 12 hours?

Answer:Consult your veterinarian that prescribed the medication for the best advice because they know the active ingredient that they prescribed but most medication for hypothyroidism, like Soloxine, and this generic, are just given every 12 hours (with or without food): https://www.1800petmeds.com/Levothyroxine-prod12031.html

Topic: medication dosage change

Question:In june my dogs total T4 was .8. , and he was put on ThyroTabs 2 x a day...dosage was .8. At the time his weight was 101 He just got retested and his Total T4 is now 9.3! His weight is 93. they lowered his dosage to 2x a day.... dosage is now .6 Someone told me that his dosage should have been raised, not lowered. Can you give me your opinion?

Answer:It depends on the reference range at the lab where they sent his blood, but 9.3 will probably be high for any lab so lowering to 0.6 seems perfectly acceptable. Why would someone think it should be raised?

Question:what should I give him to stop hair loss ibstarted to notice after I gave him a bath then 2 weeks later I notice more an more hair falling off on his back he seem healthy he drinks plenty of water eats twice a day walked every afternoon about 2hrs is there any thing you can prescribe for my doberman

Answer:There are many things that can cause hair loss, so you really need for your veterinarian to examine him and run some quick tests to make a plan for his treatment. You filed your question under hypothyroidism and that is certainly something they will want to check for.

Topic: Liver damage

Question:I have a 70 pound 11 year old female lab who has been on levothyroxine .6 mg every day for the past two years. She has shown increase signs of anxiety, and hair loss. I started the levothyroxine because of the hair loss and anxiety, it just seems to have gotten worse. her blood count is normal on the medication. But her liver enzymes came back high this year on the last blood test. Could this levothyroxine because liver issues?

Answer:Possibly, but if her T4 isn't elevated that would be unusual. If her T4 were elevated, her dosage might be a little high, but since it's not, your veterinarian might want to run some more tests on her to see what is going on with her liver.

Topic: Future problems

Question:Can hypothyroidism lead to diabetes? My dog has been on medication for hypothyroidism for 7 years. He is only 8 and is now diagnosed with diabetes. Are the two diseases related?

Answer:No - the 2 diseases are unrelated and involve totally different organs (the thyroid and the pancreas). Certain breeds are predisposed to both - that's about the only connection I can think of.
