I took Chester out for a walk on friday and he suddenly stopped when we were in the field and started what I can only describe as snorting noises. It was as if he couldn't breathe through his nose. This lasted for a few minutes then he stopped and we started to head back home and he had it again for another few minutes. It was really scary I didn't know what to do. When I got him back I took him straight to the vets and they checked his chest. It was a struggle as Chester hates the vets and gets really scared and shaky. We had to muzzle him as he was trying to bite as he was that scared. The vet basically said that she couldn't find anything wrong.
looked at me like what am I talking about
. She gave me some sedatives for him to take the next time he comes in to make him calm and told me just to monitor him. He has been fine all weekend until tonight where he had another episode of it. Am unsure of what to do at this point as the vets don't seem to know whats wrong but it clearly is something. Just really worried what it is and if it is something dangerous.
