Generally, yes, a healthy adult dog can go all night without eating. Dogs are naturally adapted to intermittent fasting, and a single overnight fast is unlikely to cause harm.
Here are some factors to consider:
- Age: Puppies and senior dogs may need more frequent meals.
- Health: Dogs with certain medical conditions, such as diabetes, may require specific feeding schedules.
- Activity Level: Highly active dogs may need to eat more frequently.
- Breed: Some breeds, like small dogs, may have higher metabolisms and require more frequent meals.
However, if your dog shows signs of illness or distress, it's always best to consult your veterinarian.
