perhaps you should contact animal control and make a report. if they have the dog tied out, and it can chew through a rope, they really aren't protecting the dog or the public.
if your poochie is afraid of the stick, try leaving it around the house where he/she can sniff it and become used to it. is doggy clicker trained? that can help. you can also try to get doggy to associate the stick with high value treats like bologna/turkey/biscuit treat of choice.
