Boos flow

Boos flow (bõõös flôw): The state in which an (animal) consumes too much of an unknown (unsafe) substance to their digestive system that leads to boos immunity, a stage that causes a dog to be so cute and humble that they no longer seem to be moving. One might say they died from their own overwhelming cuteness

My dog recently got the boos flow, unfortunately he didn't last through it. Thankfully he died looking very cute and healthy
