In addition to feeding on humans, bed bugs bite cats and dogs. Bed bugs do not live on dogs but rather live in the dogs' environment and feed on the dog.
Bed bug skin bites on a dog resemble insect bites from fleas and mosquitoes. It is rare to find live bed bugs on a dog or in the fur. Signs that point to a bed bug infestation include live bed bugs on mattresses or dog beds, finding exoskeleton molts left by bed bugs, or seeing rusty, fecal spots left by bed bugs. Anti-flea and anti-tick pet products have no effect on bed bugs.
