What it is
In a dog with atopic dermatitis, the immune system reacts to harmless particles in the air and around the home as if they were a threat. The skin becomes inflamed and itchy, and because its protective outer layer lets moisture out and allergens in more easily, the itch feeds on itself: scratching damages the skin, and damaged skin itches more. Broken skin also gives yeasts and bacteria an easier way in.
The tendency is inherited and stays for life, though the itch can be milder in some seasons than in others. Itching driven by pollen may come and go with the year, while dust mites can keep it going indoors all winter.
For you, it can mean restless nights with a dog that scratches, licks and chews, and a dog that seems irritable or unsettled. Noticing when and where the itching gets worse gives your vet useful clues.
Signs you may notice
- Licks or chews its paws
- Rubs its face on furniture
- Scratches its armpits and belly
- Red skin between the toes
- Shakes its head, scratches its ears
- Rusty-brown fur from licking
The dog spends a long time licking its paws, rubs its face and scratches its armpits, groin and belly, where the skin turns red and over time may darken and thicken. Ear infections can keep coming back as well.
When to see a vet
Book a visit if your dog keeps scratching, licking or chewing for more than a few days, or if the skin looks red, broken or smelly. Ear trouble that keeps coming back is worth mentioning too.
