They prefer humans as a food source, but not because humans are easier to bite. It's the carbon dioxide signature that is more attractive to them. Fur or hair has nothing to do with it. Bed bugs will feed on cats, dogs, birds or other animals when a human host is not present.
Humans, cats, and dogs can be bitten by the parasites, but none of us carry them on our bodies. Bed bug bites can cause itching and may exacerbate allergies in dogs and cats.
If your dog is bitten by bed bugs, you may find tiny red bumps, likely on their belly and limbs. Bed bug bites typically occur in a straight line, in groups of two or three. Depending on the length of your dog's hair, these can be difficult to spot. If your dog scratches a lot, their skin can get irritated and a bed bug rash can appear.
Bed bugs are a nuisance and more people are discovering the sad fact that a bed bug infestation has nothing to do with hygiene. Even the cleanest and swankiest hotels and homes could still get them. If you have a cat or several cats for that matter, then you may be wondering if bed bugs can harm them.
Or if your dog sleeps on a pet bed right next to your bed, the bed bugs are likely to find him there. If it's not a heavy infestation, they may just target you instead of them. However, dogs can carry bed bugs from room to room and spread an infestation if you're not careful, so keep a close eye out for any suspicious signs.
Bed bugs, also known by their scientific name Cimex lectularius L., are parasitic creatures that use blood as their sole source of nutrition. They feed on warm-blooded animals. According to the California Department of Public Health, while bed bugs prefer humans, they will feed on dogs and cats as well.
