Ok, this is a first for me and I wouldn't believe it but the proof is starting to add up. I have a spare garage that needs to be torn down and rebuilt so I keep nothing it. A stupid squirrel lives in there and drive my dogs nuts. I opened the door today and one of my dogs was in their barking at. I forgot about a pan of oil on the floor. Now I would have never thought a dog would take a drink but tonight when I was eating supper out on our deck he was sitting next to me and I noticed he was leaking from behind. This dog never has accidents and has only had diarrhea once in his life. I made him get of the deck and go sit in the yard till I finished up. At the time I thought he had diarrhea. I got the hose off and sprayed the deck clean. When I was spraying it I notice it seemed really oily and thought maybe he had an anal gland problem. I decide to wipe some up on a paper towel and see what color it is to see if it has any blood in it. I found it odd that was almost scentless, which would be weird for anal glands so I gave up on that theory. Like any good pet owner would do, I sniffed the paper towel and it smelled like motor oil. I am still not believing he could be that dumb that he drank oil so I go in the garage and sure enough their are paw prints in the oil on the floor. Then to confirm my suspicions the deck is stained with motor oil where he had been sitting. I consulted a vet and he will be okay. I is not acting sick at all. The leaking has slowed down or stopped. I don't think he drank a lot, he may have actually just cleaned his paws off because he grooms himself a lot and ingested it then. Life is never dull with dogs.
