That's a great question! A dog park definitely has unique needs when it comes to trash bins. You'll want something durable, easy to maintain, and designed to handle the specific waste. For a small urban park, I'd highly recommend looking for a specialized "pet waste station" or a sturdy, small-capacity outdoor bin.
The best options are typically metal, like coated steel or aluminum, as they resist weather and are harder for animals to damage. Look for a model with a secure, animal-resistant lid—often a hinged top or a small opening that discourages scavenging. A bin with a removable inner liner bag makes cleanup a breeze for maintenance staff. It's also smart to choose a dark color that doesn't show scuffs and to ensure it's securely anchored to prevent tipping.
Brands like United Receptacles, Glasdon, or Rubbermaid Commercial offer great commercial-grade options in smaller sizes perfect for urban spaces. Prioritize function over fancy looks; a simple, robust design will serve your park and its furry visitors best for years to come.
