Dogs are often overlooked in historic plague discussions because they usually survive plague and dog-specific fleas are not associated with transmitting plague. Yet, dogs can host many of the fleas common among rodents and others that do transmit the plague including the cat flea (Ctenocephalidis felis) and the human flea (Pulex irritans) (Gage, Montenieri, & Thomas 1994). In a case controlled study of nine US cases of bubonic and septicemic plague in 2006, having dogs in the home and particularly sleeping with a dog was a significant risk factor, probably by flea transfer (Gould et al, 2008).  There is also a growing awareness that dogs can also transmit pneumonic plague directly to humans.
