Why does your dogs lungs sound like they have water in them?

If your dog's lungs sound like they have water in them, it could indicate a condition such as pneumonia, fluid accumulation (pulmonary edema), or congestive heart failure. These conditions can cause abnormal lung sounds, such as crackles or wheezing, due to fluid in the airways or lungs. It's essential to consult a veterinarian for a proper diagnosis and treatment, as respiratory issues can be serious and require prompt attention.
