Hot Spots: Why a Small Itch Becomes a Raw Sore Overnight

What a hot spot is

A hot spot starts as a small skin irritation — a flea bite, a damp coat after swimming, an allergy itch — that the dog licks and chews into a raw, weeping, rapidly expanding sore. Thick-coated breeds in warm humid weather are classic victims.

Break the cycle fast

The treatment logic: clip the fur around the sore so air reaches it, clean gently with an antiseptic solution, and stop the licking — a cone or recovery suit isn't cruel, it's the cure. Most hot spots need a vet visit for proper clipping, topical or oral medication, and pain relief, because they hurt more than they look.

Find the trigger

A hot spot is a symptom. Fleas are the number-one cause (one bite can do it in an allergic dog), followed by allergies, ear infections (cheek hot spots), and coats that stay damp after swims. Fix the trigger or the spots return.

Prevention

Year-round flea control, thorough drying after water, regular grooming to prevent matting, and treating underlying allergies. Catch new spots early — a coin-sized sore treated today beats a dinner-plate one treated Friday.
