Anybody want my dog? She won't leave plants alone!!!

I'm sooo maddd i chained the puppy, dawg, is only 7 mths old and has decided that the plants on my porch are hers as long as they don't have any leaves, so she got my blueberry bush which was bare root and now i'm putting my bare root roses out and she's chained up! She also got my lilac cutting that i just put outside on porch as it started to get some new growth so it musta rooted right? I hope the others root too. She also got the rose I had on porch that was my DH's grandmothers, I had just brought it back from WV and now it's gone and it even had some leaves as it was a rooted cutting. SSSSSOOOOOO mad. Don't know what to do with her. My son Jeff wants me to get rid of her as she chewed up his bicycle seat (the one that's on his bike that he rides). When she did that I laughed after all she's just a puppy but now she's messing with my plants and I'm ready to get rid of her too. Isn't that terrible? After all she is a puppy, but she waits til we're not looking she got all my plants at night and didn't bother any in front of me, after the first time she got the blueberry bush, so she knew to leave them alone. I even caught her eating the chicken eggs the other day! Before putting her on the chain i showed her what she'd done but don't know if it'll do any good or not. Extremely frustrated, Tracy
