At the end of the day what was wrong with River was everything: Fluid in the lungs, in the stomach, fluid in the heart, and very high kidney levels. I think she loved us so hard, with such ferocity, that she used up her heartbeats. Thank you for your love and support. We might take some time from social media. It is the first time in 26 years we haven't had a dog. We will find a new one, and be back.
