I really feel for what you are going through, but really have no advice unfortunately. My 1st yorkie had a collapsed trachea which got worse as she aged; however, she had other complicating medical problems, so noone ever suggested the possibility of surgery for her trachea. I can understand how agonizing this decision is. All I can do is pray for your little one and for you that somehow you find the help you need for your little one.
