...One of the ways the seeds disperse is by attaching to things that come into contact with them. Animals and their fur are important ways grass seeds get transported to new locations. From an ecological standpoint, the attachment of grass seeds to sporting dogs is an important natural process. From the perspective of dogs and their owners, it is a dangerous threat. (AKC Canine Health Foundation Grant Application). The barbed grass awns, or "mean seeds," attach to a dogs coat and pierce the skin or are ingested or inhaled. Once in a dog's body, these mean seeds tend to migrate, leaving a trail of infection behind. These infections cause illness that is difficult to diagnose, and can even be fatal.
