Bug bites on dogs can be just as irritating as they are on humans! Whether fleas, black flies, ticks, or any other biting bug, your dog may experience pain, itchiness, and inflammation. Many bug bites resolve on their own, but some may require treatment.
What Do Flea and Tick Bites Look Like on Dogs?
It isn’t always possible to identify which type of bug bit your dog from the bite alone, as the bites from many different bugs often look similar. The appearance and location of the bite itself as well as considering the time of year and your dog’s recent activities can give you some clues to narrow down the suspect.
Flea bites on dogs generally appear as tiny red dots on the skin. The bites hurt and are itchy. You may also see some fine, dark, gritty material on your skin. This is flea dirt, a combination of flea feces and blood. Flea bites can occur anywhere on the body, but your dog’s back end around his tail and haunches are a prime location. If your dog is one of the unlucky ones with flea allergy dermatitis, his skin will also be red and inflamed, severely itchy, and he will suffer hair loss over time until the fleas are addressed.
Tick bites on dogs generally look like a small red circle. Dogs usually do not get the same bullseye rash that humans do. The bites themselves don’t hurt, but the area may become itchy. Tick bites can occur anywhere on the body, but are most common on the dog’s head, ears, and neck.
Black fly bites on dogs generally look like a large reddish welt and may take on a bullseye appearance. The bites hurt and are extremely itchy. Black flies travel in swarms, so your dog will likely have multiple bites close together. These bites can occur anywhere on the body, but the belly, inner thighs, and inside of the ears are common sites.
Mosquito bites look like small bumps and are usually itchy. Some dogs just get small welts from mosquito bites, while others may have more dramatic swelling.
The bites from sarcoptic mange and demodex mites are too tiny to see, but over time these infestations cause hair loss and crusty, irritated skin.
Ant bites are usually small, raised, and kind of look like a pimple. Fire ants can cause an allergic reaction resulting in widespread hives, itchiness, and even difficulty breathing. This is more common if your dog receives many ant bites at once.
Bug Bite Treatment for Dogs
Most bites will resolve on their own and heal within a few days.
For painful bites, ice the area for 5 to 10 minutes. This numbs the skin, lessening pain and itchiness, and helps to reduce swelling. You can ice your dog’s bug-bite wounds several times a day. Wrap the ice pack in a thin cloth so it doesn’t stick to the skin.
If the bites are itchy, you can apply a small amount of hydrocortisone or diphenhydramine (Benadryl) ointment to the area. Do not let your dog lick these ointments. The ideal times to apply are right before giving your dog a meal or right before taking him on a walk so he is distracted.
Dog Severe Reaction to Bug Bites
If your dog is experiencing extreme pain or swelling, it’s time to call your vet. Difficulty breathing, lethargy, or collapse after receiving a bug bite is an emergency and requires immediate care.
Based on your dog’s symptoms, the number of bites, and which bug is the likely culprit, your vet will recommend coming in for an appointment or oral medications such as Benadryl or a dog-safe pain medication.
Flea and tick bites can be prevented by giving regular preventive medications, and there are dog-safe bug sprays that can help to deter black flies and mosquitoes. If your dog is sensitive to bug bites, keep him on preventives year-round and use dog-safe bug spray when going outside during black fly season.
