DE HB293

Establishes a specific formula for calculating minimum dog enclosure space: (length of dog in inches + 6) × (length of dog in inches + 6) × 2 = required floor space in square inches, replacing references 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 hurricanes, tropical storms, heat advisories, or tornado warnings.

Specifies tether requirements including minimum length of 10 feet or 3 times the dog's length, prohibition on pinch/prong/choke collars, and requirement for access to shade, shelter, food, and water.

Prohibits tethering of dogs under 4 months of age and between 11:00 p.m. and 6:00 a.m., except for tethering periods less than 15 minutes.

Clarifies wire flooring requirements for dog enclosures and exempts temporary kennels, veterinary offices, crate training, and licensed retail dog outlets from certain space requirements.
