My girl Lily is down to her last few days and I've noticed since last night that her mucus STINKS!. Like it smells terrible and its not something I have ever smelled before. Does anyone know what might be causing this? It almost smells like rotten brocoli or something...if that makes any sence.... She does have chronic URI so I know its related to that, but she has had the URI since she was a baby and I have never noticed anything like this before... :?
