Training a dog to not chew on furniture or other household items can be a challenging task, but it is possible with consistent effort and positive reinforcement techniques. Here are some tips to help you train your dog to stop chewing on household items:

1. Provide plenty of chew toys: Dogs have a natural urge to chew, so providing them with plenty of chew toys can help redirect their chewing behavior. Offer a variety of chew toys in different textures and materials, such as rubber, nylon, or rawhide. Rotate the toys frequently to keep your dog interested in them.
2. Supervise your dog: When you’re not able to supervise your dog, confine them to a safe area, such as a crate or a puppy-proofed room. This will prevent your dog from getting into mischief and give them a chance to rest.
3. Use positive reinforcement: When you catch your dog chewing on a toy instead of a household item, reward them with praise and a treat. This will encourage them to continue making the right choice.
4. Correct unwanted behavior: If you catch your dog chewing on a household item, interrupt the behavior with a loud noise, such as clapping your hands, and redirect them to a chew toy. Avoid punishing your dog, as this can create fear and anxiety.
5. Make household items unappealing: You can make household items unappealing to your dog by applying a taste deterrent, such as bitter apple spray or hot sauce, to the items they are chewing on. This will make the items taste bad and discourage your dog from chewing on them.
6. Provide plenty of exercise and mental stimulation: A bored or under-exercised dog is more likely to engage in destructive chewing behavior. Make sure your dog gets plenty of exercise and mental stimulation through activities such as walks, playtime, and puzzle toys.
7. Seek professional help: If your dog’s chewing behavior persists or is causing damage to your home, consider seeking help from a professional dog trainer or behaviorist. They can provide personalized guidance and support to help you address the problem.

In conclusion, training a dog to stop chewing on household items requires patience, consistency, and positive reinforcement. By providing plenty of chew toys, supervising your dog, using positive reinforcement, correcting unwanted behavior, making household items unappealing, providing exercise and mental stimulation, and seeking professional help if needed, you can help your dog develop better chewing habits and keep your home safe and intact.
