Drying out and scabbing over

What this tends to look like

• A dry crust or scab across the surface, no longer wet to the touch
• Redness fading at the edges, from angry red toward pink
• Much less tender, so the dog tolerates you looking at it
• Sometimes flaky skin or a rim of dandruff around the margin
• Fur stubble beginning to appear at the border
• Occasional itch as it heals, which can restart the licking if you relax too early

What is usually going on

Scabbing is the turn. Under that crust the skin is rebuilding, and a healing hot spot mostly needs to be left alone in a way that is harder than it sounds, because the itch of healing is real and one session of chewing can reopen the whole thing.

The main mistake at this stage is picking the crust off, either yourself or by letting the dog do it. A scab is a dressing that fits perfectly and costs nothing. Softening it with something greasy, scrubbing it, or peeling it takes the surface back to day one. The second mistake is taking the cone off as soon as the area stops looking dramatic, which is usually two or three days too soon.

This is also the point to work out what caused it, because a hot spot that heals and returns in the same place is telling you something. The commonest answers are an ear that itches, fleas, an allergy, or a spot the dog can reach easily when bored or anxious.

What you can do at home

• Leave the scab alone. Do not soften it, pick it, or bathe it off
• Keep the cone on for two or three days after it looks healed, not two or three days before
• Keep the area dry and open to air. No cream that leaves the surface wet or occluded
• Very light calendula gel on the skin around the crust if it looks tight or flaky, not on the crust itself
• Trim any fur that is falling back across the healing surface
• Deal with the trigger now while you remember it: check ears, confirm flea cover, note any food change

What progress should look like

How long to give this before you conclude it is not working.

• Two to four daysCrust firm and dry, redness continuing to fade at the margin.
• One to two weeksCrust lifts on its own, leaving pink, intact skin underneath.
• Three to six weeksFur fills back in. Regrowth can come in a slightly different shade at first, which is normal.
• If it reopensAssume the licking got through, put the cone back on, and treat it as a fresh hot spot again.

When to stop and call your vet

• Fresh weeping or discharge appearing from under the crust
• The crust lifting to reveal raw, spreading skin rather than pink healed skin
• A patch that heals fully and then returns in the same place within a few weeks
• Bald skin that stays bald after two months, which is worth a look
