Can Jack Russells live on human food?

Jack Russells can eat some human food, but it's important to ensure that it's safe and healthy for them. Foods like lean meats, certain vegetables, and fruits in moderation can be beneficial, while toxic foods such as chocolate, grapes, and onions should be avoided. Additionally, a balanced diet specifically formulated for dogs is crucial for their overall health, so human food should not replace their regular dog food. Always consult with a veterinarian before making significant dietary changes.
