Sure, dogs scratch, but probably not at the rate your pooch is when a few hundred bedbugs are biting on its little dog-butt.

Look out for rashes, hives, blisters, and other irritability on your pet's skin.

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.
