I recently rescued a husky/german shepherd mix from the pound and have discovered some interesting behavior in her I've not encountered before. Luna is about a year and a half and has had a litter of puppies, though she has now been spayed. She is a joy to have, sweet and affectionate and quick to learn. My vet cannot confirm if she was previously owned or was born a stray, though she learned how to sit almost immediately, so I think it's likely she's had an owner before. I also believe she was abused, as she is excessively shy and submissive, afraid of loud noises and random, commonplace objects (if i have a shoe in my hand, she runs to her crate, but she will happily chew them to shreds if i leave them on the ground). Whenever I would reach out to pet her from above, she would urinate, though with attention, a quiet voice and lots of petting, that has been overcome. She is still fearful, though; so much so, she won't play with toys (tug of war or fetch) or chew rawhides, unless she is bored due to being crated while I'm at work (about 4 hrs a day). I take her to the dog park on a regular basis, where she is lively and obviously enjoys herself. But the only "playing" she'll do at home is "chase", where we run around in the back yard. How can I show Luna that her toys are hers and are there for fun, not to scare her? I've tried treats, peanut butter, leaving them all about so she has to pass them every where she goes... but she still ignores them 100% of the time when i am around and ducks submissively if i hold them out to her or pick them up. How can i get her to play with them, with me or by herself?
