Most Washington state parks and trails, including those in Whatcom County, require dogs to be on a leash at all times. Off-leash dogs trample habitat, chase animals, leave behind waste that can pollute groundwater and disrupt the enjoyment of other park and trail users.
Pet owners are required to remove their pets waste and dispose of it appropriately. Many trails provide doggy bags near the trailhead.
Dogs are not allowed in the following areas due to the conservation of sensitive habitat:
- Birch Bay Conservancy Area
- Canyon Lake Community Forest
- Ostrom Conservation Site
- Point Whitehorn Marine Reserve
- Stimpson Family Nature Reserve
