1. Gradual acclimation: Gradually acclimate your dog to being alone by starting with short periods of time away and gradually increasing the duration.
  2. Positive reinforcement: Reinforce calm behavior when you leave and return home with treats and praise.
  3. Exercise: Make sure your dog gets enough physical exercise before you leave so they are tired and less anxious.
  4. Provide distraction: Leave toys or puzzles for your dog to engage with while you’re away.
  5. Creating a safe space: Provide your dog with a safe space, such as a crate or a comfortable bed, where they can relax while you’re away.
  6. Training: Training your dog basic commands can help them feel more secure and less anxious.
  7. Seek professional help : If your dog’s separation anxiety is severe, it is best to seek help from a professional dog behaviorist or trainer. They will be able to give you a training plan that is tailored to your dog’s specific needs.

Also keep in mind that medication can also be an option, if above methods do not help, consult with a veterinarian behaviorist for a better assessment of your dog’s case.
