Why does my dog refuse to eat unless I feed him by hand?

Dogs may refuse to eat unless fed by hand due to various reasons such as seeking attention, feeling anxious or stressed, or simply preferring the interaction and closeness with their owner during mealtime. This behavior can be influenced by the dog's individual personality and past experiences. It is important to observe your dog's behavior and consult with a veterinarian or animal behaviorist if needed to address any underlying issues.
