Purebred,papered Bullmastiff Girl in Syracuse, New York

AKC Bullmastiff Girl for rehoming. She will be 3 in September. Very gentle, good with children and other pets. She comes with leash and collar. She is an INDOOR ONLY girl who has been crate trained. She is also super quiet and well behaved.She has been raised around both a cat and a chihuahua. Serious inquiries only. She needs to be a part of the family and makes an absolutely useless guard dog. Just a big ole sweetie. Weighs about 100 lbs... so kinda on the small side for a Bullmastiff. I am located in Philadelphia, New york which is about an hour or so from Syracuse, New york.
I am firm on the price for her. I believe given the time, training and initial expense, and her excellent health that 350 is a reasonable price for her. We will be ETS-ing this summer and we will be relocating to Georgia. We will have to stay with family and she doesn't allow dogs in her house. We aren't going to be able to afford kennel boarding and due to her breed we can't have anyone on base take care of her until we are situated in our own home.
Update: As of 4/7/2014 She is still available and unspayed. I am still on waiting list for spay. I have no idea how long it is going to take to get the spay done. She has full AKC breeding rights and her paperwork is available for an additional 100.00.
