Sorry I didn't answer this last night. A pulmonary effusion (or pleural effusion) is the build up fluid around the lung. It's caused by problems with the heart or liver (long story short, the osmotic pressure changes in the capillaries and they leak). Pneumonia on the other hand is an infection within the lungs that causes fluid to build up inside. Both give a whitish appearance on the xrays. Gas (air ) build up can occur both inside the lung and outside of the lung and is something that needs to be watched.
Either cause can lead to difficulties breathing in your dog. I'm kind of surprised they sent him home if he was wheezing. Please keep a sharp eye on your dog for any increase in the wheezing, very fast breathing, excessive panting. Take him to the nearest ER vet if this happens. The lethargy can also be a sign that he isn't getting enough oxygen.
Please keep us updated on how your little one is doing.
