For most minor sores on dogs, a gentle rinse with clean water or saline followed by a thin layer of a pet-safe antiseptic is the safest starting point. What you choose depends on the type of sore, how deep it is, and whether your dog can be kept from licking it off. Some common household products that seem helpful, like hydrogen peroxide or diaper rash cream, can actually make things worse or poison your dog.
Clean the Sore First
Before putting anything on a sore, you need to clean it. The simplest and safest option is lukewarm water or sterile saline solution, which you can buy at most pharmacies. Gently flush the area to remove dirt, debris, and dried discharge. If the sore is on a furry area, carefully trim the hair around it with blunt-tipped scissors so you can see and access the wound clearly.
For sores that look mildly dirty or crusty, a diluted chlorhexidine solution (sold at pet stores and pharmacies) works well as an antiseptic rinse. Cornell University’s veterinary college recommends cleaning surface sores with a mild soap like Dove, Cetaphil, or Castile soap, or with a chlorhexidine-based antibacterial cleanser. Pat the area dry with a clean gauze pad rather than rubbing it.
Safe Topical Treatments
Once the sore is clean and dry, you have a few options for what to apply. The right choice depends on whether the sore is a shallow scrape, a hot spot, or something deeper.
Chlorhexidine spray or solution: This is one of the most widely used antiseptics in veterinary medicine. A 2% chlorhexidine solution is a standard concentration for skin disinfection in dogs. You can find pre-diluted sprays marketed for pets at most pet supply stores. It kills bacteria on the surface without the tissue damage caused by harsher products.
Triple antibiotic ointment (Neosporin): A small amount of over-the-counter triple antibiotic ointment can be applied to minor scrapes and shallow sores. It contains three antibiotics: bacitracin, polymyxin B, and neomycin. Bacitracin and polymyxin B are generally considered safe for dogs. Neomycin has been linked to hearing issues with heavy intravenous use, so some vets recommend avoiding it. The bigger practical concern is that if your dog licks off a significant amount, the ointment base can cause vomiting and diarrhea by disrupting gut bacteria. Use only a thin layer, and only on sores you can cover or monitor.
Veterinary wound sprays: Pet stores carry antiseptic wound sprays designed specifically for dogs. These typically contain chlorhexidine or a mild iodine-based formula and are formulated to be safe if a small amount is licked. They’re a convenient option for minor sores in hard-to-bandage spots.
What About Honey?
Medical-grade manuka honey has legitimate wound-healing properties and is used in some veterinary clinics. In a controlled trial comparing manuka honey to untreated wounds in dogs, the honey-treated wounds had a significantly smaller wound area on ultrasound evaluation. Honey creates a moist environment, has natural antibacterial properties, and can help with slow-healing or dry wounds.
The key word here is “medical-grade.” Regular grocery store honey is not sterile and could introduce bacteria into an open wound. If you want to try this approach, look for medical-grade manuka honey products sold for wound care, and apply a thin layer covered by a non-stick bandage. This is better suited for wounds your vet has already examined rather than as a first response to an unknown sore.
What NOT to Put on a Dog’s Sore
Several products that seem like obvious choices are actually harmful. VCA Animal Hospitals specifically warns against using hydrogen peroxide, rubbing alcohol, tea tree oil, herbal preparations, soaps, or shampoos on open wounds unless a vet directs you to. Hydrogen peroxide and rubbing alcohol damage healthy tissue and can slow healing significantly. Tea tree oil is toxic to dogs if ingested.
Zinc oxide cream is another common mistake. Products like Sudocrem (which contains over 15% zinc oxide), diaper rash creams, and some sunscreens are sometimes applied to irritated dog skin, especially around the rear end. But dogs lick these areas, and prolonged ingestion of zinc oxide causes zinc toxicosis. One documented case involved a dog that developed zinc poisoning simply from repeatedly licking a zinc oxide cream that had been applied to its skin over time. Even small repeated exposures add up.
Human cortisone creams, calamine lotion, and medicated acne products should also stay away from your dog’s sores. Many contain ingredients that are toxic when licked or that irritate already damaged skin.
Keeping the Sore Moist and Protected
Letting a wound “air out” is outdated advice. Moist wound healing is now the standard of care in veterinary medicine, and studies confirm that wounds heal faster, require fewer bandage changes, and cost less to treat overall when kept appropriately moist compared to wounds left dry or treated with traditional dry gauze.
For minor sores you’re managing at home, this means applying a thin layer of your chosen ointment or antiseptic, covering with a non-stick pad (like a Telfa pad), and securing it with a light wrap of conforming gauze and self-adhesive bandage tape. Don’t wrap too tightly, especially on limbs. You should be able to slide two fingers under the bandage. Change the dressing once or twice daily, cleaning the sore each time.
For sores in spots that are hard to bandage, like the face, ears, or belly, a thin application of antiseptic spray that dries quickly is more practical than ointment.
Stopping Your Dog From Licking
The biggest challenge with any topical treatment is keeping your dog from immediately licking it off. Licking introduces mouth bacteria into the wound and removes whatever you just applied. An Elizabethan collar (the plastic cone) is the most reliable solution, even though dogs hate them. Inflatable donut-style collars are a more comfortable alternative for sores on the body, though they don’t work as well for sores on the paws or lower legs.
For paw or leg sores, a light bandage covered with a dog boot or clean sock secured with tape can work in the short term. Bitter-tasting anti-lick sprays exist, but they should not be applied directly on an open sore. Use them on the bandage or surrounding fur instead.
Signs a Sore Needs Veterinary Care
Not every sore can be managed at home. A sore that is deep enough to see tissue beneath the skin surface, larger than a quarter, or located near the eyes, ears, or genitals warrants a vet visit. The same goes for any sore that appeared suddenly and is spreading rapidly, which could be a hot spot that needs prescription treatment.
Signs of infection include redness and swelling that worsen rather than improve over 24 to 48 hours, warmth around the sore, yellow or green discharge, a foul smell, or your dog developing a fever (warm ears, lethargy, loss of appetite). A sore that your dog won’t stop biting or scratching at, or one that keeps coming back in the same spot, also needs professional evaluation to rule out underlying causes like allergies, parasites, or skin infections that topical home treatment won’t resolve.
