AKC 2 Year Old Aussie in Apex, North Carolina For Sale

As hard as this is, I am looking to find a new home for my dog. I have had her ever since she was 9 weeks old. She is a purebred Australian Shepherd, AKC registered. She turned 2 years old on March 5, xxxx. She is a GREAT dog and has been my best friend for almost 2 years. Unfortunately, I no longer have the time that I thought I would have to get her the amount of exercise she needs to be happy and to be a good dog. She is crate trained and potty trained. I allow her to sleep out of the crate at night but she goes in the crate when I am not home. When she was 8 months old, I took her through a six week puppy training class. She knows the basics (sit, down, paw, crate, up (to get in the car)). However, she still needs work on "come" and "stay." I've really worked hard with her to not jump on people and she's gotten much better but could use more work. She is up to date on all her shots, she is microchipped and spayed!
She needs a home that has land where she can run and get lots of exercise and play time! Serious inquires only. I am looking for a rehoming fee to get a little back of what I've put into her and to make sure the person is serious about giving her a good home. I have put $xxxx+ into her (I am NOT looking to get all of that back). Please email me if you are interested. Feel free to makes a reasonable offer.
Thanks!
