Wonderful news! I hope they continue to improve!

I hope you can help me!!!!!!! I am desperate!!! My girl is sick and I just don't know what to do....I feel like our vet is "guessing" what could be wrong with her and I feel like she is getting worse-not better. she has been seen by a vet but we believe they are just guessing what could be wrong with her. they have her on pimobendan (they are guessing heart disease)but we believe that medication might be causing her open mouth breathing to be worse? she has had an X-ray, negative fecal test, blood work--which showed one parameter that was outside the normal range was heterophiles. the percentage of heterophiles among the various types of WBC's was high...she has been tested for aspergillus but we do not know the results of that test yet. she is eating and pooping normally. I have noticed when she's in her house area that she lays with her neck stretched out. she coughs every so often and has had some sneezing. she is disabled (can't walk) so she is kept on the screened in porch area. they do have her on carprofen indefinitely for her disabled leg. does anyone have any ideas? I have been giving her some nutridrench in her water.
