When extreme weather conditions make walking outdoors unsafe, there are several indoor alternatives to keep dogs active. Interactive games like tug-of-war or hide-and-seek engage a dog's mind and body. Puzzle toys or treat-dispensing toys can stimulate their problem-solving skills. Setting up an obstacle course at home using furniture or portable ramps can provide physical exercise. Additionally, short training sessions using positive reinforcement can be mentally and physically enriching. These activities help maintain a dog's fitness and prevent boredom without the need for outdoor excursions.
