Why is my hypothyroid dog skinny and vomiting after medication?

With regurgitation secondary to megaesophagus dogs usually can’t keep any solid food down and continually regurgitate shortly after eating. I would guess that the episode is unrelated to hypothyroidism or the medications- although I’m not entirely sure why cimetidine was prescribed. It is also very rare for hypothyroidism to cause megaesophagus. The good news is that if megaesophagus does occur secondary to hypothyroidism supplementation with thyroid hormone should reverse the disease.

If you have a copy of Milo's medical record, you can choose a Petco Pet Education Center, formerly Petcoach Consult to discuss this fully. Hypothyroidism does not usually cause weight loss in dogs, and the test may be caused by euthyroid sick syndrome, meaning the thyroid hormone is low because of some other illness. There are confirmatory tests that can help your vet decide if Milo needs to be on thyroid therapy. If there are no other abnormalities on a CBC and complete blood chemistry, then additional diagnostics may be indicated, including intestinal parasite screen, GI panel, x-rays, abdominal ultrasound, etc. If Milo has a good appetite without vomiting or diarrhea, you could try feeding more calories. I like Purina ProPlan Sport. You could also try puppy food, which is higher in fat. If you do decide to switch food, mix them together slowly over 2-3 weeks to avoid an upset stomach.

I'm sorry that Chewie is not feeling well. Unfortuantely, vomiting is a very non-specific symptom. Pretty much anything can cause vomiting in dogs so I cannot tell you why this is happening. You are doing just right by withholding food. Just be sure to offer only small amounts of water at a time. If he continues to vomit in the next 6-8 hours you should get him to the vet right away. Continued vomiting can be serious.

Hi there! Thanks for letting us take care of you today! This is unlikely to be due to the thyroid medication. When there is evidence of blood in the vomit, that raises concern for things like a gastrointestinal ulcer, gastrointestinal tumor, severe gastroenteritis, foreign body ingestion, among other possibilities. Some tests that are usually run include bloodwork (CBC and chemistry panel +/- coagulation profile) and abdominal ultrasound. Thoracic/cervical/ abdominal adiographs may follow. Further diagnostics will be based on the findings up to that point. Keeping my fingers crossed that everything will be fine with Tiekie!

As per Dr. Elbeze, hyperthyroidism is quite rare in dogs. The main cause of this in dogs is thyroid carcinoma or there is a lab error. I would make sure to have the thyroid level tested again and confirmed and have a free t4 rather than a total t4 tested. If Soska has hyperthyroidism, I would recommend speaking with a veterinary oncologist about further testing and treatment.

It sounds as Vinny is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

Since it has been several hours, inducing vomiting will not help. Dogs take higher doses of thyroid medications than humans do, so it is likely that Roxy will be fine. He may develop some stomach upset. Monitor for rapid heart rate, panting and restlessness or hyperactivity. These are symptoms that should be addressed by your veterinarian or at the nearest veterinary ER. You can also contact the Pet Poison Helpline ( https://www.petpoisonhelpline.com/ ). They are staffed by toxicologists who have more detailed information. There is a fee for the call. https://www.petpoisonhelpline.com/poison/thyroid-medications/
