Leash rules
DRMC 8-16(a) makes it unlawful for any owner or KEEPER of a dog to fail to prevent it running at large. 'Keeper' is you while you have the dog. Denver specifies no maximum leash length: the duty is framed as preventing the dog from being at large rather than as a measurement, so a retractable lead that lets a dog range is a problem even though no number is being broken.

Licensing & vaccination
DRMC §8-31 requires rabies vaccination for dogs over six months, and a dog acquired after that age must be vaccinated within 30 days. Denver licensing follows the same shape: dogs over six months must be licensed within 30 days of reaching that age or of arriving in the city. Confirm both at intake and keep records accessible. After an incident, vaccination status is the first thing anyone asks for, and 'the owner has it somewhere' is not an answer at the moment it matters.
