Minnie’s paw moves before the rest of her body seems ready for it.

The seven-year-old Maltese mix is sitting hunched on a towel inside the shelter’s medical kennel. Nearly half of her body has lost its coat. Instead of the soft white fur expected on a Maltese-type dog, large areas of exposed skin are red, irritated, crusted, and marked by places where repeated scratching has already damaged the surface.

For a while, Minnie sits quietly.

Then her hind leg rises.

Her paw reaches toward her neck.

Scratch.

Scratch.

Scratch.

The movement is quick and almost automatic.

Then Minnie suddenly stops.

Her body tightens.

The paw hangs in the air for a moment before slowly returning to the towel.

The itch told her to scratch.

The damaged skin told her she couldn’t.

A few minutes later, Minnie tries again.

Minnie Arrived With More Than Simple Hair Loss

Missing fur is the most visible part of her condition.

It is not necessarily the most important.

The skin underneath is inflamed.

Some areas are intensely red.

Others are crusted.

There are superficial wounds where Minnie has scratched herself repeatedly.

That means she is dealing with two problems at once.

Something is making her skin itch.

And the scratching itself is creating additional injury.

The Cycle Can Become Difficult to Break

Itching produces scratching.

Scratching traumatizes already inflamed skin.

That trauma can increase irritation.

The irritated area may become even more uncomfortable.

Then the urge to scratch returns.

For Minnie, the cycle has progressed far enough that scratching no longer seems to provide simple relief.

It hurts.

Yet the urge remains.

Her Neck Is One of the Places She Keeps Reaching

Minnie sits with her body slightly curled.

Her hind paw lifts.

She reaches toward the side of her neck.

For the first second or two, the scratching is rapid.

Then the motion changes.

Minnie slows.

Her shoulders tense.

Sometimes she pulls her head away from her own paw.

Finally, she stops.

The skin she is trying to relieve has become too sore to tolerate the thing her body keeps telling her to do.
