my american bull needs a good loving home

Hi all,
I am sure you all love your american bull dogs as I myself do. Recently out of the blue she nipped at my neighbors daughter and punctured her nose. Im not sure if she caught her nose with her claw or if she actually nipped her. she has been raised with all my children ranging from the ages of 11 to 3. I have 4 in all. I am scared this will happen again so I am looking for a good loving home for her before i place her with the spca where I feel her fate may be death. she is very loyal but subborn at the same time. It is hurting me tremendously to have to part with her but I have alot of children in and out of my home and have lost trust in her. If there is anyone out there who doesn't have children and is looking for a loving companion and evoted friend please contact me. she is 20 months ols up to date with her shots and licensed she is about 75-80 pounds. Her parents are Sir napolean dynamite and mother madam rathbuns cloe I know owners of her grandparents are apart of this forum and I am hoping someone will want her. she is house trained and I think this nipping was an accident but im not sure and cannot take the chance of her doing it again. I dont feel she should e put to death for humand have done worse. I love her very much and hope someone will want her please e-mail me at momica8181@netzero.net or phone me at 716-861-9582 if interested. im not asking anything for her but I would ask only those willing to love and treat her right contact me. Im running out of time for soon i will have to resort to the spca again I would like to avoid that she deserves better and it is hard to part with a family member without knowing her fate.
