Molzy, my Cavalier King Charles has the same symptoms. After multiple tries with different Chinese herbs, acupuncture, dietary changes, etc. we finally took her to a specialist who scoped her throat and bronchials. (While in there he took photos that he later showed us.) It turned out that her left bronchial is 95% collapsed and her right bronchial is 75% collapsed. (She’s never worn a collar when walked, just a soft harness. The doctor believes it is genetic.) At the same time he removed a small amount of excess palette tissue that was touching the back of her throat. The collapses are after the bronchial tubes split so she is not a candidate for surgery. My husband did some research and we have her on some good supplements designed to rebuild cartilage which has helped quite a bit. (She used gulp/panic/eat grass several times a day and night. Now she has an episode once every couple of days.) When it happens, I find that if I open her mouth (which she actually comes to me to do), stick my finger toward the back of her tongue and then gently pull her tongue forward, they’ll be a soft popping/suction-release sound and she’ll feel better. Occasionally this doesn’t work, so when that happens I just let her go outside and eat a bit of grass so she can throw up and clear her lungs. We’re planning to take her back to the vets soon to have her re-scoped so we can see if the supplements have arrested the collapse and possibly rebuilt them in some way. If you’re interested, I’ll let you know the results. Good luck–your pup is lucky to have you.
