You can remove dog odors easily and inexpensively. Follow these steps.
Splish-splash, give him a bath. A simple bath can alleviate some unpleasant odors. Bathe your dog every 4 to 6 weeks with a gentle shampoo and warm water.
Clean the carpet with baking soda. Since most dogs love to lounge on the floor, odors can linger in the carpet. Sprinkle the baking soda over the affected areas and let set for several hours (even overnight). Finish by vacuuming.
Freshen your laundry. If your clothes smell of dog, add apple cider vinegar to your regular laundry detergent. About 1/4 cup added to your laundry detergent should get the job done.
Scrub clean the hardwood floors. Use a 3:1 mixture of warm soapy water to white vinegar in a bucket. Mop it onto the surface until the odor vanishes.
