What it is
The skin is a dog's largest organ and its first barrier against the outside world. When that barrier is irritated, whether by an allergy, fleas or mites, an infection, a hormone imbalance or a fold where moisture gets trapped, it can react in only a handful of ways: it itches, reddens, flakes, darkens, thickens or loses hair. That is why very different problems can look alike on the surface.
Some skin problems are inherited or linked to build, such as deep skin folds or a thin, short coat that leaves the skin exposed. Others are acquired, or show up as a sign of illness elsewhere in the body.
An itchy dog may sleep badly, seem restless or grumpy, and lick or scratch through the night. It helps to note when the itching started, whether it changes with the seasons and where on the body it is worst, so your vet gets a clear picture.
Signs you may notice
- Scratching, licking or nibbling
- Red or flaky patches
- Thinning coat or bald spots
- Scabs or lumps in the skin
- Darkened skin
- Unpleasant smell from the coat
You may notice the dog scratching, licking or nibbling at their skin, patches that turn red, flaky or darker, a thinning coat, scabs, lumps or an unpleasant smell.
When to see a vet
Book a visit if itching keeps your dog from settling, if a patch of skin is not getting better within a week or two, or if you find a new lump.
