the most my vet said about her heart was something is pushing it but never really concluded much. I had another vet look at the X-ray since the first wasn't sure. one of her lunges was 1/2 larger than the other and he said it had fluid in it. That's what lead him to thinking it was pneumonia and he said that's what is pushing on her heart. The next time I took her the lunge went down some
This is the first time she has ever coughed like this
which makes it so heart breaking
So an enlarged heart can cause this?
