**ISO** a awsome dog trainer for my 1 yr old pitbull... she knows basic comands such as sit off and sometimes no barking. shes never really been on walks because she was my xs dog and we split up. I need help!.. shes friendly when other dog are indroduced to her but if a dog is walking on the street and shes in our back yard she goes crazy...if anyone knows of a trainer please let me know... thank you !
