I moved in for a couple of weeks to help my aunt when she broke her hip. She had an 8 month old miniature dachshund, Pippa.
Absolutely adorable puppy but every now and then I would see a glint in her eyes, naughtiness would take over...she would jump up and tear leaves from big house plants, try to play and mess around with cables under a desk, take anything she could from a bedroom, particularly socks, paper and tissues.
There was a huge garden with lots of doggie toys, all fenced, but she managed to find a gap and dig and wriggle through. Got her back with treats and blocked the gap.
Solution was to take her to the woods nearby, on long leash, 4 times a day, where she could chase and bark at squirrels and big dogs and dig holes to her heart's delight and come back exhausted.
Pip is now almost two, has had some obedience training, you still need to pick her up when you answer the door and to stop her habit of peeing on the guest's shoe. Its her special greeting!
Caring for my aunt actually was a doddle...
