How Can I House Train My Dog?
Begin by thoroughly cleaning all areas where he has eliminated with a pet-specific cleaning solution and odor neutralizer. If necessary, hire a professional carpet cleaner. The key is to make sure all previous odors are entirely removed so that he’s not attracted back to the same spot.
Next, do not allow your dog to roam the house without you until you’re sure he’s 100% reliable. If you can’t be with him, consider confining him to a crate. This will give you the chance to interrupt him should he start to relieve himself. (Never yell at or hit your dog; this will only encourage him to go when you’re not looking.)
Take him immediately to an appropriate area, preferably one he has used before. The scent of his prior eliminations will “remind” him of what he’s supposed to do there. Once he relieves himself, reward him by being generous with both praise and treats.
