No, they aren't. There is a big green county sign at all trail heads with a bucket load of rules in small print. This lady wasn't interested in 'rules', as most abusers aren't. She wanted the entire park to herself and her 4 monster dogs.
Today, I picked up a dozen beer cans/bottles and 2 empty 'dime bags' that held crack or other drug, all forbidden. Working a park is a constant human study.
The problem with more than one dog is "pack behavior". The nicest dogs change in a pack. I really didn't want to tangle with 400 lbs. of dog.
