Welcome to Pet Talk Cudos to you for realizing that life on a chain is no life at all for a dog; it only prompotes aggession, nervous behavior and frustration. Her desire to jump is probably a result of having been restrained for so many years. Understandably she want to run and explore and if she's a natural jumper, well I guess she figures up is the way to go! Is there any reason why she cannot be in the house during the day, when no one is home; is she allowed in the home during the night, in cold weather? Building her an enclosed kennel outdoors, with a wire top might be an option if for some reason you can't bring her indoors. If for some reason she can't be trusted with free roam of the house, as has been said, you could try crate training or perhaps initially, gating off a safe area of the home, say the kitchen, and with time, you can increase her acccessability to other areas of the home. It's never to late to teach a dog...You might try calling up a trainer in your area for suggestions/advice. She/he would probably have some good suggestions on how to acclimate her to the home and obedience classes are always a good idea, at any age! Good luck to you! Your pup is lucky to have such a caring and concerned guardiaan! Please, let us know how it goes! Hugs to your pup!!!
