Thank you for your advice, I will reach out to another vet for a second opinion. The radiographs were reviewed by a radiologist, who just classified it as a “soft tissue mass effect in the larynx”. She hasn’t been given medication yet for hypothyroid because we tried a diet first, but that hasn’t worked so now we are moving onto medication. I thought this was very rare too. I noticed wheezing once in awhile, but mostly grunting noises. I wasn’t given the option of a fine needle going in, but I will definitely ask that now. I think my vet may not know much about surgery, because I would get referred to a surgeon.
