Some dogs take a one-mile walk and are tuckered out for the rest of the day. Others can play fetch for two hours and stare blankly at you, as if to say, "What now?" Tiring out your hyper pup calls for a lot of physically demanding exercise and a bit of mental stimulation. A day at the dog park and a night with the treat dispenser can work wonders.
Take at least two walks a day. With a hyper puppy on your hands, occasional walks aren't going to calm her. Even twice-daily walks won't do the trick without supplemental exercise, but the walks are a good start, especially if your little girl isn't used to them.
Take your pup to a dog park or enclosed area. Running down other dogs, romping around and having a bunch of canine fun is where your pup will get really worn out and blow through her massive energy reserves. Off-leash exercise is vital for any dog, but especially a hyper one. If you don't feel comfortable at dog parks, or if your pup's too aggressive, take her to an enclosed area or field and let her run around freely. Throw her favorite ball as far as you can and make her chase you.
Play games every day. When you wake up in the morning, play fetch for 30 minutes or so. Play other games, like tug-o-war, as time allows. A 5- or 10-minute session of fetch isn't going to put a dent into her energy level, but a few longer sessions throughout the day can help tire her out.
Outfit her in a backpack and take a hike. Backpacking doesn't only allow your pup to look cool and flashy in front of all her canine friends, it's also extremely effective at tiring her butt out. Remember to start out slow and let her adjust to the physical demands of backpacking. Plot out your trip and take a leisurely walk the first few times, then place a light backpack on her and gradually increase the weight she has to lug around.
Go for a swim. Swimming requires a lot of work on the part of your pup. A little time at the lake puts a 2-mile walk to shame. As with backpacking, start out slow. If your little girl has never been in water before, she may be hesitant. Lure her in with tasty treats or one of her favorite toys. Always choose a lake that allows dogs. For the first few times, go on a weekday, if possible. The fewer people and dogs she encounters, the less hesitant she'll likely appear.
Exercise her mind. Even with a day full of physical stimulation, your pup might still appear restless at night instead of zonked out by the couch. Mental stimulation is just as important as physical stimulation. Practice obedience and new tricks, give her a treat dispenser to toy around with or create a puzzle or two for her to figure out. For example, let's say you have a small cardboard mailing box lying around. Hide her favorite toy inside of it and fold the flaps down so she has to figure out a way to retrieve the toy.
