My 10 yr old ISH has started to cough and quid. Vets have been out 3 times. They cant find anything wrong with his breathing, his teeth, sinuses or chest. He's just finishing his 3rd course of antibiotics and , tbh, theres no real improvement.
he's quite bright in himself, has a play in the field and otherwise seems normal.
Some days he coughs up a thick creamy discharge, other days nothing. But the quidding is definitely getting worse and I think he's lost a bit of weight, although he is finishing his net every night.
Any ideas? Im wondering about a rotten or broken tooth? My vet dismisses this but he doesn't have any other ideas and they haven't done an X-ray
