3 of our 4 dogs like beer, but I found that they won't drink it if it's flat...I poured about 1/2 of a can of Bud as a treat for the dogs, they all drank up...I put it back in the fridge, open, for a couple of hours...they would not drink the flat beer, but when I opened a fresh one, they all got thirsty again.
