The effect of alcohol on a dog’s liver is the same with people. Their kidneys are not designed to filter the alcohol content of wine, beer, or hard liquor, and since they are smaller than us, it takes far less amount of alcohol to do the same amount of damage, or more. It can cause them to vomit, have diarrhea, depression, difficulty in breathing, coordination problems, coma, and in extreme cases, even death.
