I just found out im 6 weeks pregnant and i have a wonderfull pitbull she is a big part of my family.She doesnt walk good on leash's i gotta walk her but it gets hard. She will always pull me and trys to play with any dog she sees. if she see;s another dog she will yank and pull on me which isnt good. how can i make her walk good on the leash and stop pullin and tuggging? I wanna keep her daily rounteen walks but i need some adive so she doesnt hurt the baby.
