Anyone need a ranch dog?

So apparently one of my dogs, Izzie (the Hildebrant's old dog), is an escape artist and can get out of my backyard, despite my 6 ft, cinder block wall (much to the dismay of my neighbors). I don't have the money to build the wall any higher, and her and Darcy aren't getting along as swimmingly as I had thought, so I'm looking for a new home for Izzie.

She's VERY sweet and calm.  People always comment on how sweet she is...and she loves taking naps with you.  I actually think she's jumping out of the backyard to escape my dog who always wants to play. She likes her space (she acts like a dog who's 15 years old and she's only 2), so if little kids get too clingy with her, I've seen her growl or nip at them to get them to not hang on her. Currently she is sleeping on her little doggy bed snoring away...she loves to nap. She would come with a dog bed, collar, leash, and choke collar...which is for walking her because she pulls a lot. She has her vaccines but would need to be licensed under the new person's name.

She's very calm in the house, but honestly, because she's half boxer, she needs a LOT of exercise. The best thing would be for her to be with someone who has lots of space or likes to do a lot. Does anyone know anybody who lives out in the desert who has space and wants a dog? She listens very well - knows sit, lay down, and we were working on stay. When I take her for walks in the wash, I let her off her leash and she runs and runs, but comes back the instant I whistle or call for her. She doesn't jump, but again, doesn't walk well just on a casual stroll to the park because of her energy level. I've also taken her hiking or in the snow, which she loved, but she hates water or swimming.

 Izzie (or sometimes I call her Lizzie, like Darcy and Lizzie from Pride & Prejudice :D) is on the left

If anyone hears of anyone interested, please call Layne at 520-306-1194.  I would love for her to have a good home!  She was at the Humane Society, then my friend's house, and now mine, so finding her a permanent home would be great.
