Hmm.. You would think this is a no brainer, but I guess it's something people don't think about. Liquor, wine, beer and any foods containing alcohol has the same effect on a dog’s liver and brain that it has on humans. Consuming even a little can cause severe intoxication. Consumption of alcohol can cause vomiting, disorientation, alcohol poisoning and in severe cases, coma, seizure and even death. Make sure to keep your drinks and foods cooked with alcohol out of your dogs reach.
