The Dog has a Heart Murmur

What's it saying, I wonder. He's a dog. He intuits things. Now his heart is out of sync with him. It's making a noise, a low thrum instead of the thwop thwop sound it used to make. The vet is concerned. Specialized tests are required. I know they'll find something. They always do. Sometimes he seems depressed. Our hearts, the dog's and mine, are simpatico. Mine doesn't feel quite right either. It beats too loudly. It feels too large for my chest. I have more of a mumble than a murmur. What's my heart telling me? I listen but I don't like what I hear.
