DE HB60

Establishes a formula for calculating minimum dog enclosure size: (length of dog in inches + 6) × (length of dog in inches + 6) × 2 = required floor space in square inches, replacing reference to federal regulations.

Requires dog houses used as winter shelter to include dry, water-resistant materials such as straw or hay and a door flap; prohibits leaving dogs outside during hurricane, tropical storm, heat advisory, blizzard, flood, or tornado warnings.

Sets minimum tether length at the lesser of 10 feet or 3 times the dog's length; prohibits tethering dogs under 4 months of age and prohibits tethering between 11:00 p.m. and 6:00 a.m. unless for less than 15 minutes.

Prohibits tethering when using pinch-type, prong-type, or choke-type collars, when tether is inappropriate for the dog's weight, or when it inhibits free movement or causes injury or entanglement.

Requires dogs kept primarily outdoors to have access to spill-proof water receptacles and running water available on the property; clarifies exemptions for temporary enclosures, veterinary offices, grooming facilities, and retail dog outlets.
