Whitby Off Leash Dog Park South (9y2, 470 Jeffery St, Whitby, ON L1N 9Y2, Canada) features divided areas to keep little dogs safe from the big guys, and thirsty dogs can drink from the water fountain, and natural shade makes it comfortable year-round. Regulars here are welcoming and their dogs are well-socialized. It gets muddy after rain, so plan accordingly.
