Dogs cannot drink milk

Dogs cannot drink milk. Dogs generally suffer from lactose intolerance. Lactose intolerance means that a dog's body cannot produce enough lactose-breaking enzyme to digest large amounts of dairy products. If a dog drinks milk that exceeds its digestion capacity, it will cause indigestion and diarrhea, and in severe cases, it can even lead to the death of the dog.

Dogs can’t drink alcohol

Dogs can’t drink alcohol. Dogs can get drunk, and their tolerance to alcohol is much worse than humans. A small amount of alcohol can cause great harm to a dog's body. Alcohol poisoning will not only cause motor dysfunction in dogs, but also cause damage to cardiopulmonary function. Some ingredients in wine and beer, such as grapes and hops, are potentially toxic to dogs. No matter what kind of alcohol it is, it can bring fatal danger to dogs.

Dogs cannot drink coffee or tea

Dogs cannot drink coffee or caffeinated drinks. Caffeine poisoning in dogs is as serious a health hazard as alcohol. Because dogs weigh much less than humans, very small amounts of caffeine can have adverse effects on dogs, just like alcohol. Caffeine is easier to ingest than alcohol and is more easily ingested by dogs. Caffeine poisoning in dogs can cause high blood pressure, increased heart rate, hyperactivity, and can be fatal in severe cases.
