My 7month old Whippet has an adam's apple. I thought it was normal, until my vet recently noted it. She took an x-ray and said he has a prominent bend in his cranial trachea where his trachea meets his larynx. She said it wasn't a problem if it doesn't cause him any issues or get worse. Just to keep an eye on it. If anyone has ever heard of this please let me know. I'm still very concerned. Thank you
