She was a stray walking with her mama at about 7lbs, she has gained 50 more lbs! We didn't grab the pup because we were afraid of the mama dog. So we gave them water & food. Later an old man saw the pup seperate from her mama and posted her picture up. I thought it was the owners so I called to inquire. The old man begged me to take her, and I caved in, and fell head over heels in love with her. After 6mo of age she was showing signs of fear aggression. It is at this point that we know we can no longer care for her because her needs are beyond what we can provide. PLEASE HELP!
