Glad to hear that Tootsy (love her name!

) is on the road to recovery from whatever was ailing her!
Also, something that is beneficial when your pet can't seem to replicate the symptoms that you observe at other times (when it comes time for the Vet to see or listen to)...is to "video-tape" these episodes that you witness. Then you can play them back for the Vet to see & hear.
When my Bella was displaying symptoms that I was concerned could be Collapsed Trachea my Vet was first to suggest that it could just be a reverse sneeze. Long story short...I ended up trusting my gut that it was more and video taped an episode for him to see & hear. An x-ray later and voile' my instincts were correct and my girl was properly diagnosed...she unfortunately has CT
