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.
Training: Training your dog basic commands can help them feel more secure and less anxious.
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.
