The Dog

Dogs and coyotes leave similar signs, which may be difficult to distinguish from one another. Domestic dogs may attack and bite many parts of the body, but leave the carcasses of the birds. Usually multiple birds are severely injured or killed.

How to Prevent Dog Attacks

Fencing : Install well maintained woven wire fences that are 6 to 7 ft (1.8 to 2.1 m) high. Install electrically charged wires along the bottom and top of woven wire fences to increase their effectiveness.
