There are two important reasons to license your dog in the Town of Castle Rock.

1. Dog tags get stray animals home and reduce shelter stays.

2. License fees support important animal welfare initiatives.

Our Partnership with DocuPet

Pet licenses are really important. Pets with license tags are much more likely to be returned home by Animal Control Officers or good Samaritans without ever seeing the inside of the shelter. When licensed pets do make their way to the shelter, their tag helps get them home quickly. Fees from pet licensing also help support important initiatives that protect animals in our community.

We've partnered with DocuPet so that residents of Castle Rock can take advantage of their free 24/7 Lost Pet Service and designer tag upgrades.

Personalized Tags

Tags That Help All Pets

Our tags help lost pets get home safely. They also help fund local animal welfare initiatives that find safe and happy homes for vulnerable animals in our community.

Now you can choose from our selection of fun tag designs. We can also etch your pet's name and your phone number on any tag you choose.

Any tag you choose will serve as your official license tag. Cool, huh?

HomeSafe Logo

Every DocuPet tag comes with a unique code tied to our free HomeSafe™ Lost Pet Service. If your pet becomes lost you can send Lost Pet Alerts to local pet owners who will use your code and our 24/7 Hotline to reunite you.
