Bed bugs don’t actually live on dogs. Unlike fleas and ticks, which burrow into fur and set up camp, bed bugs hide in the environment and only climb onto a host long enough to feed. If you’re finding bites on your dog or spotting bugs near their sleeping area, the real problem is your home, not your pet. Getting rid of bed bugs “on” your dog means addressing the infestation where it actually lives: in furniture, baseboards, carpeting, and bedding.
Why Bed Bugs Don’t Infest Dogs
Bed bugs strongly prefer human hosts. Fur makes it harder for them to navigate skin and feed, so they gravitate toward exposed human skin instead. A bed bug might temporarily cling to your dog while moving between hiding spots, especially during a severe infestation, but it won’t stay there. It will feed and leave, or simply pass through on its way to a crack in the bed frame or a fold in the mattress.
This distinction matters because it changes your entire approach. Treating your dog with topical products the way you’d treat a flea problem won’t solve anything. The Companion Animal Parasite Council confirms that flea and tick products are not labeled for bed bugs, and because bed bugs feed primarily on people, treating pets is not an effective form of control.
Checking Your Dog for Bed Bugs
If you suspect bed bugs have been crawling on your dog, inspect their fur carefully. Adult bed bugs are flat, oval, reddish-brown, and roughly the size of an apple seed. Nymphs (younger bugs) are smaller and translucent to pale yellow. Look closely around your dog’s belly, ears, and any areas with thinner fur where feeding would be easier.
You may also notice small red bite marks on your dog’s skin, though these can be tricky to spot under fur and are easy to confuse with flea bites or skin irritation. The biggest clue is usually what you find in the environment: tiny dark spots (fecal stains) on your dog’s bedding, shed exoskeletons, or live bugs hiding in seams and folds of fabric near where your dog sleeps.
Removing Bugs From Your Dog
If you’ve found a bed bug on your dog, a simple warm bath is enough to wash it off. Use a gentle dog shampoo and work through the fur thoroughly, paying attention to areas where a bug could cling. There’s no need for medicated shampoos or insecticidal rinses. You’re physically removing a hitchhiker, not treating a parasitic infestation. After the bath, comb through your dog’s coat with a fine-toothed flea comb to catch anything you might have missed.
This is a one-time cleanup, not an ongoing treatment. The bug that was on your dog came from somewhere in your home, and more will follow until you deal with the source.
Decontaminating Your Dog’s Bedding and Gear
Your dog’s bed, blankets, crate liners, plush toys, and fabric collars are all potential hiding spots for bed bugs. Heat is the most reliable killer. Bed bugs die within 20 minutes at 118°F, and eggs require 90 minutes at the same temperature to reach full mortality. A household dryer set on high will exceed these thresholds easily.
For washable items, run them through the washing machine on the hottest setting the fabric can handle, then transfer to the dryer on medium-high or high for at least 30 minutes. The University of Minnesota Extension notes that temperatures above 122°F for 20 minutes kill all life stages, and medium-high typically reaches this threshold. For items that can’t be washed but can tolerate heat (stuffed toys, fabric harnesses, small dog beds), toss them directly into the dryer on medium-high for 30 minutes.
Hard plastic items like crate trays and food bowls can be scrubbed with hot soapy water. Inspect crate seams and joints carefully, as bed bugs favor tight crevices. If your dog’s bed has a non-removable foam insert, you may need to seal it in a black plastic bag and leave it in direct sunlight on a hot day, or discard it entirely if the infestation is significant.
Why Flea and Tick Products Won’t Help
It’s tempting to think your dog’s monthly flea prevention might kill bed bugs too, but these products aren’t designed for that purpose. Standard topical and oral flea treatments are not labeled or recommended for bed bug control.
That said, there is early research worth noting. A 2022 study from North Carolina State University tested two common veterinary drugs against bed bugs in a lab setting. One compound, the active ingredient in several popular oral flea and tick chews, caused high mortality in bed bugs that fed on treated animals for up to 28 days after dosing. It was even effective against bed bugs resistant to common insecticides. However, this research used artificial feeding systems and chickens, not dogs in real-world conditions, and no bed bug treatment for pets has been approved based on these findings. Your dog’s flea chew is not a bed bug solution right now.
Bed Bug Sprays and Your Dog’s Safety
Many over-the-counter bed bug sprays contain pyrethroids, a class of synthetic insecticides. Permethrin is one of the most common. While permethrin is used in some flea products formulated specifically for dogs, the concentrations in household bed bug sprays are not calibrated for animal safety. Dogs exposed to permethrin on treated surfaces may twitch their skin or ears, shake their paws, roll on the ground, or drool excessively if they lick a treated area.
If you’re using any bed bug spray, fogger, or powder in your home, keep your dog out of the treated area until it has fully dried or settled and the room has been ventilated. Never apply a bed bug spray directly to your dog or their bedding. Read product labels carefully for pet safety instructions, and store all pesticides out of your dog’s reach.
Treating the Real Problem: Your Home
Because bed bugs live in the environment rather than on your dog, the only lasting solution is treating your home. Bed bugs hide in mattress seams, box springs, headboards, baseboards, electrical outlets, carpet edges, and upholstered furniture. They can travel between rooms and will continue to bite both you and your dog until the infestation is eliminated.
Start by reducing clutter around sleeping areas, which gives bed bugs fewer places to hide. Vacuum thoroughly along baseboards, furniture seams, and under beds, then seal and discard the vacuum bag immediately. Encase your mattress and box spring in bed bug-proof covers to trap any bugs inside and prevent new ones from settling in.
For significant infestations, professional pest control is typically necessary. Heat treatments, where a room is brought to sustained temperatures above 120°F, are among the most effective options because heat penetrates hiding spots that sprays can’t reach. Chemical treatments applied by professionals use targeted products in precise locations, reducing the risk to pets compared to DIY spraying.
During treatment, you’ll likely need to remove your dog from the home temporarily. Coordinate with your pest control provider about when it’s safe for pets to return, as timelines vary depending on the method used.
Preventing Bed Bugs From Reaching Your Dog
Once you’ve addressed an infestation, a few habits help keep bed bugs from coming back. Wash your dog’s bedding weekly on hot settings during and after treatment. Keep your dog’s sleeping area away from walls and upholstered furniture where bed bugs travel. Use light-colored bedding so you can spot the telltale dark fecal stains early. If your dog sleeps in a crate, inspect the joints and seams regularly.
When traveling with your dog, check hotel rooms before settling in. Pull back bed sheets and inspect mattress seams and headboards for small dark spots or live bugs. Keep luggage and your dog’s gear off the floor and away from upholstered furniture. Bed bugs are excellent hitchhikers, and a single trip can bring them home.
