Wine is toxic and must never be given to dogs under any circumstances. Wine contains two serious hazards: ethanol, which causes acute alcohol poisoning, and grapes or grape juice, which contain unknown toxins that damage the kidneys. Even a tiny amount of wine is extremely dangerous. Dogs cannot metabolise alcohol efficiently and are far more susceptible to its effects than humans. The combination of alcohol and grape toxins makes wine doubly hazardous. Symptoms of wine toxicity include intoxication, hypothermia, vomiting, diarrhoea, abdominal pain, and potentially death. If your dog has consumed any wine, seek immediate veterinary emergency care.
Why Wine Should Be Avoided
Toxic to dogs; contains both alcohol and grapes (which are themselves extremely toxic).
What To Do If Your Dog Eats Wine
Monitor your dog for vomiting, diarrhoea, lethargy, or loss of appetite. If symptoms develop, contact your vet.
Use the Emergency Risk ToolCommon Mistakes
Watch out: Owners may not realise wine contains both alcohol and grape toxins. Some think a tiny sip is harmless. Never allow any wine consumption. All alcohol is dangerous for dogs.
