In the US, it's down to the owner of the playground to decide whether dogs are allowed to be left off their leash or on the leash on their premises, which is why it's necessary to have a sign on your land. The Aluminum On-Leash Pet Sign allows you to let your visitors know whether their dogs can be let off their leads or not. This particular sign will tell people with dogs that their dogs need to remain on the leash all of the time. The sign says this very clearly so that there is no confusion. You may purchase this on-leash pet sign individually, or you will also receive it with a pet station package. Either way, you simply need to make sure that dog owners know where they stand in terms of dogs and leashes on your premises.
