Your dog scratches one spot raw. The skin turns red. A sour smell shows up. Most cases come down to yeast or bacteria on the skin, and a medicated spray handles the trouble at home.
A good spray kills fungus, calms the itch, and dries the spot out. We’ve gathered the top five sprays to help fight the itch, get rid of the redness, and clean up that sour smell.
Disclaimer: spreading sores, open wounds, and clumps of lost fur need a vet, not a spray.

Veterinary Formula Clinical Care Antiseptic and Antifungal Spray

This spray outsells every rival in the category, and it’s the most affordable. An 8-ounce bottle runs about $9. Most other products of similar quality are double that.
Spray hot spots, ringworm patches, and raw skin between the toes. The chlorhexidine fights bacteria and fungus on the skin. Owners rate it 4.5 stars.
Spray the full spot once or twice a day. Keep your dog from licking the area for a few minutes after each spray, and try to prevent scratching as much as possible.
Pet MD Antiseptic and Antifungal Medicated Spray

Pet MD pairs chlorhexidine with ketoconazole, the two active ingredients vets reach for on yeast. Aloe and vitamin E are also in the formula and calm the skin while the active ingredients work.
Pick Pet MD for yeast trouble: paw licking, crust at the ear edges, and a musty smell on the belly and armpits. The 8-ounce bottle runs about $17. Owners rate it 4.5 stars.
Vetnique Dermabliss Chlorhexidine Medicated Spray

Dermabliss packs a strong label: 2% chlorhexidine plus 1% ketoconazole. The mix covers bacteria, yeast, and ringworm in one bottle.
Pick Dermabliss after a lighter spray failed or the patch keeps coming back. The 8-ounce bottle runs about $22. Owners rate it 4.4 stars.
Truseb Advanced Strength Medicated Spray

Truseb holds an Amazon’s Choice badge in this category, with 4.4 stars across 1,612 ratings. The formula pairs ketoconazole with chlorhexidine and adds aloe for sore skin.
The 8-ounce bottle runs about $18.
Smiling Paws Pets Advanced Chlorhexidine and Ketoconazole Spray

Smiling Paws runs the same two active ingredients, 2% chlorhexidine plus ketoconazole, at about $17 for 8 ounces. Owners rate it 4.4 stars across 1,371 ratings.
The label covers dogs and cats. One bottle serves a mixed pet home.
How to use an antifungal spray
- Part the fur. Spray needs skin, not coat.
- Cover the full patch plus a small ring of skin around it.
- Keep your dog busy for a few minutes. Licking wipes the medicine off.
- Repeat once or twice a day until the skin looks normal. Then go one extra day.
- Wash your hands after each use.
Spray or shampoo
Spray wins for one or two spots. A medicated shampoo wins when the trouble covers the back, belly, and legs. Big flare-ups need both: a bath twice a week, spray on the off days.
Check for fleas before you blame fungus. Flea bites drive a big share of itch cases. Find fleas or flea dirt, and the fix starts with a flea dip, then skin care after.
When a spray is not enough
See a vet when the patch spreads fast, the skin bleeds or oozes, fur falls out in clumps, or two weeks of spray change nothing. Puppies, older dogs, and dogs with weak immune systems skip the home trial and go straight to the vet.
Bottom line
Start with Veterinary Formula. The price sits near $9 and the track record runs deep. Move to Dermabliss if the first spray stalls. Spray skin, not fur, and give each pick two full weeks before you judge it (or change).
