11 Month old Mini Australian Shepherd in Mc Donald, Pennsylvania For Sale

I have a beautiful black and white Australian Shepherd, she's 11 months old, and on the "mini" side, she's approx. 20 pounds. She's the perfect Aussie! She's very energetic and needs a home with room to run and play!! She also loves to cuddle up with you on the couch! She smiles when she's excited and will give hugs and kisses! We got her as a baby and we just love her so much, but she is very aggressive with our cat and she bites my kids. We have put up baby gates to keep her contained to one room in the house and it's just no life for her, she needs room to run and enjoy herself! A home without kids or cats would be ideal for her unless you can train her to stop this behavior, we have tried but it seems to just be in her nature to need to herd the kids and cat. She does good with other dogs after she meets them, but can be a little stand-offish at first due to her protective nature. She is "fixed", microchipped, registered and has all her papers, she is up to date on all her shots and has no health problems! She is fully house broken and bell trained to alert when she needs to go out, she listens to commands like sit, wait, come, no, down, up (she needs constant reinforcement of the commands, if you slack off, so will she!). She loves being with people, she's just better with adults! She comes with her crate, food/water bowls, many toys, a small bin of food and her treats, as well as her collar, leash, (we have an e-collar and a regular leash for her)
