Butler Farm Dog Park

Address: 44 Singletary Rd, Millbury, MA 01527

Membership is required here — registration is quick and the fee is paid at town hall, after which dogs can use the large fenced off-leash area with agility equipment, a water fountain, and a dog washing station. Dogs are split by size, and there's grassy space to roam. The entrance can be tricky to find the first time, and there are no public restrooms on-site.
