A wound they keep licking, that is not closing

What this tends to look like

• Still moist and open days after it should have been drying
• Surrounding fur stained, matted, or licked away in a widening ring
• Skin around it thickened, darker, or roughened from repeated licking
• Sometimes larger than it was on day one, which is the key observation
• Occasionally discharge or a smell developing
• Often on a leg, paw or flank, wherever the animal can comfortably reach

What is usually going on

A wound that is bigger or wetter on day five than it was on day one has stopped following the normal course, and there are only a few reasons for that. The commonest by a wide margin is mechanical: saliva keeps the surface wet, the tongue removes the new fragile surface cells each time, and the wound cannot get ahead. The idea that licking cleans a wound is one of the more durable pieces of folklore, and it is wrong for anything past the first minute.

The other reasons matter enough to need a vet rather than more cream. Infection, a retained foreign body such as a grass seed or a splinter, and in some cases an underlying problem that is preventing healing, will all produce a wound that stalls. So will a wound in a location that moves constantly. Distinguishing between those requires someone looking at it, and quite often a swab or a probe.

There is also a behavioral tail to this. Persistent licking of one spot can outlast the wound entirely and become a self-sustaining habit, which is how acral lick granulomas start. Those are genuinely difficult to resolve once established. Breaking the licking now, properly and completely rather than most of the time, is the thing that prevents that outcome.

What you can do at home

• Get it seen. A wound stalled past a few days needs a diagnosis, not another product
• Stop the licking completely in the meantime. Partial prevention is the same as none
• A recovery suit is usually better tolerated than a cone and covers body and flank wounds properly
• Keep it clean and dry between checks with water or saline only, and let it air
• Photograph it daily against something for scale. The size trend is the most useful thing you can show a vet
• Note whether the licking happens at particular times, such as when left alone or in the evening

What progress should look like

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

• This weekVeterinary assessment. Retained foreign bodies and infection both need finding rather than guessing at.
• Two to four days after licking genuinely stopsA purely licking-driven wound starts drying almost immediately. That in itself is diagnostic.
• One to two weeksShould be closing steadily once the cause is dealt with and the licking is fully prevented.
• If it still will not healAsk about a swab and imaging for a foreign body. A wound stalled at a month rarely resolves without one.

When to stop and call your vet

• Discharge, smell, or spreading swelling
• The wound growing rather than shrinking
• Thickened, raised, hairless skin building up, which is early lick granuloma
• Lethargy, fever, or refusing food
