It's common for dogs to develop separation anxiety, which can manifest as a lack of appetite when their owner is not around. To help your dog overcome this, try gradually desensitizing him to being alone by leaving him for short periods of time and gradually increasing the duration.

Additionally, providing a comfortable and safe space for your dog to relax in while you're gone can help alleviate his anxiety. If the issue persists, consider consulting a professional dog trainer or behaviorist for further guidance. **
