Angelle,
Im so sorry your little one Candy was dx with Tracheal Collapse. I dont know much about it. But i found this link you can read some info.

I think as long she is walking some that is helpful that none walks at all. You should talk to your vet to put Candy on a weight loss program. Good luck with your little one. Please keep us posted. Welcome to YT.
