The Barnum Dog Park is a special area for dog exercising in the public Barnum Park in the city of Denver, Colorado. The most convenient vehicle parking for using the facility is accessible from W. 5th Avenue. This park is a designated off-leash zone specifically for dogs. It measures approximately three-quarters of an acre in size and is divided into two sections. There is no specific area for small dogs, but rather one for quieter pets and another area for the livelier ones.
The off-leash area is surfaced with a fine grade gravel mixed with dirt. It is surrounded by a sturdy, waist-high chain-link fence. There are a few trees outside of the fence perimeter. These do not offer any shade for pets inside the off-leash park. The Denver authorities require any dog using the off-leash park to be vaccinated against rabies and to be displaying the tag on their collar at all times while at the park. Dogs too young to be vaccinated against rabies are not permitted entry into the park. Dogs must also be correctly licensed. If a dog has not been spayed or neutered it must have a current Denver Intact Permit.
Because of the soft nature of the off-leash area's surface, pet owners are responsible for filling in any holes dug by their pets. There are no facilities for pet owners inside the off-leash area, but there is a picnic area and a restroom, which are part of the main park, outside of the dog park. Dogs are permitted in the main park if kept on their leash at all times. The Denver authorities request pet owners to bring extra supplies of poop bags and leave them in the bag dispensers to assist in keeping them stocked. Owners are also invited to join the Denver adopt-a-dog-park program to help keep the city's ten dog parks open.
