Going to bed last night, I took our little dog Bucky, out for his pre-bed walk, he went around behind the house for about 30 seconds and when he came back he was different. Very lethargic and unresponsive...usually after doing his duties, he’s all about finding my wife who at that time is usually getting ready for bed as well. Last night he walked into the house and laid down at our bedroom door. That caught my eye and I started checking him out. He was out of it and soon started drooling and I started worrying...the wife held him and after a while he seemed to improve...He Still was not back to normal this morning so we took him in to the vet...blood test shows stage 2 liver disease, he is ~11 years old...they are hydrating him and trying to ease his nausea...probably going to change his diet...my only question is this seemed so sudden, not sure if liver issues work like that. It almost seemed like a poisoning or at least accidental poisoning...he was in my garden during the potty walk but I don’t leave ferts or chemicals lying around and believe me, i checked this morning to make sure... we’ll get him back this afternoon...
