This means gradually getting your dog used to being alone, starting with short periods of time and gradually increasing the amount of time as your dog gets more comfortable.
A tired dog is a good dog. Make sure your dog gets plenty of exercise before you leave them alone. This will help them burn off some energy to relax when you're gone.
Puzzle toys and interactive games can help keep your dog's mind active and prevent them from getting bored when you're gone.
Crate training can be a helpful way to prevent separation anxiety. It teaches your dog that their crate is a safe and comfortable place to be, even when you're not there.
Desensitization is a process of gradually exposing your dog to being alone in a controlled environment. This can help them learn to associate being alone with positive things.
Counterconditioning is a process of pairing a negative stimulus with a positive stimulus. This can help your dog learn to associate being alone with something good.
When you leave your dog, try not to make a big fuss. This will only make them more anxious about being left alone. Just give them a quick pat and a treat, and then calmly leave the house.
