I think it could extend that far. Up the nose, down the throat, into the stomach or lungs. I think the lack of appetite and not pooing regular is more resulting from the excessive mucous. I also think if it were allergies, he would be sneezing all the time, not just every 3-4 days.
If you get it on film, you may be able to email it to the University. An x-ray would be helpful, but I really think it will be visible in his nose and throat when they do the exam. So you may get away with just the exam and x-ray fee.
My pup's episodes were so violent, I was waiting for her to have a heart attack. It took quite a few tries looking up her nose with a flashlight everyday at different times to try to see something. Then I saw something bright green, maybe the diameter of a dressmaker's pin. I grabbed my tweezers and very slowly removed a blade of grass. The odd thing is that the tip of the grass came out first. So that means that she ate the grass, then vomited and this blade of grass went up her nose instead of coming out of her mouth, and got lodged there. |
