Our last Yorkie did that once and we had a hard time finding the cause. We finally figured out he had some of his long muzzle hair inside his mouth along his teeth/gums and he had swallowed it down his throat. He couldn't swallow it completely and he couldn't cough it up so he just kept trying. We trimmed his muzzle hair after that!
Also, while we lived in Florida Riley chewed on an oak leaf and swallowed a piece of it...oak leaves in Florida are like leather! He had it stuck in his throat and we tried everything to get it to go down. He finally either swallowed it or coughed it up. Riley would also sleep fine but cough when he was awake.
Good luck...I hope Oscar will be o.k. |
