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.

Puppy Issues

When puppies play with each other, they use their mouths. Therefore, puppies usually want to bite or “mouth” hands during play or when being petted.

Housetraining a puppy requires time, vigilance, patience and commitment.

At the Dumb Friends League, we believe that dogs of all sizes are happier, healthier and safer when they can be indoors with their people the majority of the time.

Many behavior problems in dogs are the result of boredom or excess energy. Toys offer mental and physical stimulation and enrichment.

An aversive is something that your dog finds unpleasant. It can be used to discourage her from a particular action or place.

Submissive urination occurs when a dog feels threatened.

Knowing why dogs bite and what to do to keep yourself safe is important.

Living with a dog can be beneficial to children. However, children and dogs may not always automatically start off with a wonderful relationship.
