I adopted an american bull from a shelter. she had (has) a lot of issues and we are working on them but one thing i just can't understand i how she hates my 17 yr old daughter...it's not a jealously issue because she is fine with my husband but she will stalk and seriously attacks my daughter for no aparent reason so, when my daughter is home lexi is either in her cage or has her muzzel and leash on and oh yes lexi attacks with the muzzel on. we have been to a behavoirist but i can't say she helped at all. i love this dog and will do what is necessary to keep everyone safe if anyone has delt with this type of problem...i could use some advise
