Itchy dog: causes and what helps
Itching is the most common reason owners go looking for a new shampoo. Before you buy anything, it is worth working out where it comes from, because shampoo solves only some of the cases.
The most common causes
- Parasites. Fleas and mites. One flea is enough for weeks of itching in an allergic dog. Check the base of the tail and the belly for black specks.
- Environmental allergies. Pollen, dust, grass. Seasonal itching on the paws, belly, armpits and ears is typical.
- Food allergies. Rarer, but year-round, often with ear and stomach problems.
- Dry skin. From frequent bathing, the wrong shampoo, dry winter air, a diet low in fats.
- Infections. Bacteria and yeast, usually as a secondary problem. Recognisable by smell, redness, greasy or sticky skin.
When to go straight to the vet
- An open, wet, hot wound that grows within hours (hot spot)
- Hair loss in patches
- A strong smell that comes back days after a bath
- Itching that wakes the dog at night or lasts more than two weeks
What you can do at home
- Rule out parasites. Regular flea and tick protection all year, not just in summer.
- Switch to the mildest shampoo you can find. No fragrance, no silicones, dog-skin pH. Rinse twice as long as feels necessary.
- For seasonal allergies, wash more often, not less. A bath with a mild shampoo, or just rinsing the paws and belly after a walk, removes pollen from the skin.
- Support the barrier. Omega-3 fatty acids in the diet (fish oil) are one of the few things with good evidence for skin. Discuss the dose with your vet.
- Keep notes. When the dog scratches, where, after what. That is the most useful thing you can bring to the vet.
