Pit bull group welcomes ban's end with parade PAWTUCKET, R.I., Nov. 20 (UPI) -- A Rhode Island group that trains pit bulls to be service dogs is celebrating a town's ban on the breed being overturned with a pit bull parade. The Pit Bulls for PTSD nonprofit, which trains put bulls to become service animals for autistic children and people suffering from post traumatic stress disorder, said pit bulls and their owners are being invited to march with the group Sunday in Pawtucket to celebrate a court striking down the city's ban on the breed. The court ruled the city's ban, which was passed in 2004, violates a 2013 state law barring cities and towns from banning dogs and cats by breed. The parade Sunday will begin at 1 p.m. at the Slater Dog Park, Pit Bulls for PTSD said. Dog owners are being asked not to use retractable leashes during the march.
