We had a dog that learned to barf in a plastic bag when she was sick. After she puked on hubby's lap when he was driving.Sammy just pukes wherever he happens to be and I'm too crippled to run him up the stairs in the middle of the night. Our dogs are not allowed on the furniture and thankfully we don't have carpet anywhere. I once had a dog that would bark, asking to be let out when he felt sick. I trained him to do that. He would even do it in the car. What a great dog.
