Identify the cause of the barking (e.g., boredom, fear, territorial behavior) and address it. Use positive reinforcement to teach a "quiet" command. Ensure your dog gets enough mental and physical exercise.
Aggression can stem from fear, anxiety, or territorial issues. Consult a professional dog trainer or behaviorist for help. Do not punish aggressive behavior, as it may exacerbate the problem.
Gradually desensitize your dog to your departure cues and practice short departures. Provide interactive toys and puzzles to keep them occupied when you're not home. Consult with a veterinarian or behaviorist for severe cases.
Provide appropriate chew toys and rotate them regularly to keep your dog engaged. Puppy-proof your home, use bitter apple spray on items your dog shouldn't chew, and supervise them closely until they learn appropriate behavior.
Ignore your dog when they jump up and only give attention when they have all four paws on the ground. Teach them a "sit" command to replace jumping.
Train your dog to walk on a loose leash using positive reinforcement. Consider using a no-pull harness or head collar to assist with training.
Provide a designated digging area with soft soil or sand. Praise and reward your dog when they dig in the appropriate spot and discourage digging in unwanted areas.
Housebreaking requires patience and consistency. Stick to a regular feeding and potty schedule. Supervise your dog indoors and take them outside frequently, especially after meals or waking up. Clean accidents with an enzymatic cleaner to eliminate odors.
