Identify the trigger for aggression and address it. Consult a professional dog trainer or behaviorist to help modify aggressive behavior through positive reinforcement and desensitization exercises.
Gradually accustom your dog to being alone by leaving for short periods and gradually increasing the time. Provide toys, treats, and a comfortable space to ease anxiety. Consider crate training.
Identify the cause of barking (attention-seeking, fear, boredom) and address it. Use positive reinforcement to reward quiet behavior. Consider providing toys or puzzles to keep your dog occupied.
Ensure your dog has appropriate chew toys. Supervise them until you are confident they won't chew on inappropriate items. Provide mental stimulation through puzzle toys and regular exercise.
Teach your dog an alternative behavior, such as sitting, and reward that behavior consistently. Ignore the dog when they jump up and reward when they exhibit the desired behavior.
Provide a designated digging area filled with sand or soil. Supervise outdoor time, and redirect your dog to the designated area when they start digging. Ensure your dog gets enough physical and mental stimulation.
Train your dog to walk politely on a leash using positive reinforcement. Stop and wait when your dog pulls, rewarding them for walking without tension on the leash.
Use positive reinforcement to make coming to you a positive experience. Start with short distances and gradually increase. Avoid punishing your dog when they come to you, as it may discourage them from returning in the future.
