The Dumb Friends League has a history of service. For more than 100 years, we have sheltered and cared for lost, abandoned and abused pets. 

Thanks to wide community support, we offer programs that help both pets and people. 

We are proud to be the metro-Denver area’s local humane society. You are invited to visit our website and our two shelters to learn more about us.

Dog Behavior Tips

Please explore the sections on the menu to the left to help resolve your pet's issues.

Please note: If you are experiencing a behavior issue with your dog, please visit with your veterinarian about the problem right away. Sudden changes in behavior are often caused by underlying medical issues. In many cases a trip to the veterinarian can save you time and frustration, and help prevent potential harm to your pet(s) and loved ones.
