Last December the state put up signs along hiking trails in response to attacks by loose hunting dogs.
A year later, some residents still aren't following the rules designed to keep people and pets safe.
On a beautiful weekend, many hit hiking trails around Hawaii to get away from the crowds and civilization.
"We love to get into nature, get away from the hustle and bustle. Hiking is a great way to do that," said Manoa resident Ted Bohlen.
Humans don't always go it alone, pets are also found on popular paths.
Some of these trails are also used by hunters and their dogs.
Problems in the past prompted the state to put up the new signs so everyone would know what rules to follow, but not all are paying attention.
"Many pet owners don't realize it is important to have your dog on a leash, in and out of the forest. It's important to have control of your dog," said Aaron Lowe, Oahu's Trail & Access Specialist.
According to the rules, there is one type of dog allowed off-leash -- hunting dogs. Those animals play a big part in keeping the lush, forest areas pristine.
"Dog and knife hunting is very effective in eradicating pigs in our forests. Keeping those feral populations down is very important to us," said Lowe.
