A few weeks ago, i started noticing my silkie roo was drinking a ton of water. It seemed to just keep getting worse. Well today I went out to check on him, and it appears that he's drank so much that its literally coming back out.. You can see it coming out of the edges of his mouth, bubbles are coming out of his tear ducks, and when he breathed through his nose it was all gurgly.. I'm panicking because my vet office is already closed for the weekend. Does anyone know what this is??
