Bonnie the cav i took on awhile ago with a grade 5 murmer is now doing very bad. She is coughing the whole time and nothing seems to ease it. Poor thing is sounding so distressed the whole time. Am bringing her to vets in the morning but is there anything i can do to ease things. I know i went through this with Sam but he didnt have this constant cough. Poor mite cant even get of the sofa without a coughing fit. Would Bonnie be as distressed as it sounds.
