What will happen if a dog eats humas?

Humans are not part of a dog's natural diet and can be harmful if ingested. Dogs can experience gastrointestinal upset, such as vomiting and diarrhoea, if they eat human food, and some human foods, such as chocolate, grapes, and onions, can be toxic to dogs. If your dog has eaten human food, it is important to monitor them for signs of distress and contact your veterinarian if they experience any adverse effects.
