Start with very short departures and return before your dog becomes distressed
Gradually increase time away in small steps
Keep departures and arrivals calm and low-key
Practice leaving without making a big fuss
Provide a safe, comfortable space for your dog
Use crate training only if your dog is comfortable and relaxed in a crate
Leave your dog with a worn shirt or blanket that smells like you
Give a long-lasting chew, puzzle toy, or food-dispensing toy before leaving
Make sure your dog gets enough exercise before you go out
Keep a consistent daily routine
Avoid punishing anxious behavior
Desensitize your dog to departure cues like keys, shoes, and coats
Use background noise like soft music or white noise
Consider a dog sitter, dog walker, or daycare if needed
Ask a veterinarian about medical causes or treatment options
Work with a certified dog trainer or veterinary behaviorist for severe cases
Monitor for signs of distress and adjust the training pace
Reward calm behavior when you return and during practice sessions
