    Please remember that Pima County Code (Chapter 6.04.030) requires dogs to be leashed and under control and also requires pet waste to be immediately picked up and properly disposed of in a sanitary manner. This applies to public spaces such as parks, trails, The Loop, open space, nature resource areas, river beds and most every public space except “dog parks”.

    Thank you for your anticipated compliance.
