⚡ Quick answer: Clip the fur around the lesion, gently clean with dilute chlorhexidine (or vet-approved antiseptic), pat dry, and apply a thin layer of an anti-itch/antibiotic spray. Use an e-collar to stop licking. Most hot spots respond in 3-7 days; deeper or spreading lesions need a vet.

What you should actually do
- Hot spots are usually caused by allergic itch + bacterial overgrowth from constant licking.
- Hair clipped + area kept DRY is more important than any single topical product.
- An Elizabethan collar (cone) is non-optional for 5-7 days – relapse rate without one is high.
- Painful, weeping, or spreading hot spots need vet-prescribed oral antibiotics + steroid.
- Recurrent hot spots are a sign your dog has an underlying allergy that needs management.
Hot spots (acute moist dermatitis) are self-inflicted: the dog licks, the area gets wet and warm, bacteria multiply, the itch intensifies, and the dog licks more. The cycle is broken by clipping (so air can dry the lesion), antiseptic cleaning, and preventing further licking. Owners who skip the e-collar see the lesion explode overnight.
Practical at-home protocol: clip with electric clippers (do NOT use scissors near the skin), clean with diluted chlorhexidine (Hibiclens diluted 1:10 in water, or a vet anti-bacterial wipe), pat dry, apply a thin coat of Banixx, Vetericyn, or Bactine, and put on a cone. Repeat the clean-and-spray cycle twice daily for 5 days. If the lesion is deep, oozing pus, expanding past the original margin after 48 hours, or the dog is painful enough to flinch, book a vet visit. They’ll usually prescribe a short course of cephalexin + a low-dose steroid taper.
