I have an 8 month old chihuahua X JRT and since we got him, he's had episodes where he sort of hacks/ sneezes. he stands with his head down and his mouth closed when he does it. I've googled and found references to "reverse sneezing" which is when they get an irritation on their soft palette. It suggested covering the nose when it happens (to make them take a breath through the mouth) and that sort of works, although he doesn't like it. He's fine when the episode passes, it might last 20 seconds if we don't intervene. It does seem to be happening more often, maybe 3 or 4 times a day.
I did read that this can be common with chihuahuas but I don't know whether I should be going to the vets about it. I keep trying to catch a video of him doing it to show the vet but he stops by the time I get my phone out.
Does anyone have any experience of this?
