I just bacame a proud owner of a Yorkie, I love my Lil Man so much, his name si CoCo,

I didnt think That little thing could bring so much joy into my life, but he has it gives me something to look forward to come home to....And my fiance loves him too... Well yesterday night my poor thing started to cough as if he had a hairball stuck in his troath and then he was spitting out some clear mucus or something like that... the poor thing i was so worried,

b/c i dont know what i was, well my fiancee spended most of the night up with him taking care of him, making sure he was ok and taking care of him, when i woke up this morning to get ready for work my fiancee and my Coco were both sleeping on the couch and coco was laying on his chest, i wish i had my camera with me at that moment b/c it was priceless picture....Well i had my fiancee rushed coco to the vet this morning the vet calle me back just to let me know that Coco has collapsed trachea???

What the Heck is that?????

Yes i have tried to reseach that but why does it happen and now what? does he need surgery? No idea.... All i know is that i dont want anything happening to my baby....
WISH ME LUCK....
