About the Park
Fully fenced and set aside for bigger breeds, this large-dog area in Union gives sizable dogs a secure place to run off-leash. The enclosing fence lets powerful, fast dogs open up without wandering off. Union, the seat of Franklin County west of St. Louis, sees the full sweep of Missouri seasons, from hot, humid summers to cold winters, so water on warm days is a good habit. There is no fee, as it operates as a public park. Surface details and posted hours are not confirmed in our records, so check them when you get there. For owners of a large, energetic dog around the Union area, the fenced layout adds a welcome margin of safety to off-leash play.
infoWhat to Know Before You Go
Large Dogs is fully fenced, so your dog can run and play off-leash without worry. This makes it a great choice for dogs still working on recall or for owners who want extra peace of mind.
