I am 27 yrs old. My aunt volunteered to let my Smerican Bull Dog stay at her house while my new apartment was being painted. After two weeks, she said he needed to stay couple more weeks because her trainer was working with him along with her two dogs. After those two weeks she refused to return my dog saying she had become attached & she believes he is better off with her and her female partner than with me. I raised & trained this dog from time he was 5 wks old. He is now 10. He has a chop in my name. She lives in gated community & I can't even see him. How can I force her to return my pet.
