The coyote was last seen running north on Calle La Montana, according to police.
Moraga police, Moraga-Orinda Fire Department and Contra Costa County Animal Services officials responded but did not find the animal, and investigators do not know if it is the same one that has done previous attacks in the Lamorinda area.
Police said there were no life-threatening injuries, but are warning people to not leave small children or pets unattended outside, and to take extra precautions during dusk and dawn times when coyotes are known to be more active.
A neighbor took a picture of a coyote in the same area of the attack just 20 minutes prior. That neighbor pointed out the black spot that can be seen on this coyote s tail.
