Constant scratching is one of the most common reasons dogs see the vet. Here are the usual causes and what you can do to bring relief.

Quick answer: The most common reasons a dog itches so much are fleas, environmental or food allergies, dry skin, and yeast or skin infections. Safe relief starts with parasite control, gentle skin care, and daily skin support; see your vet for raw skin, hair loss, or no improvement.

The most common causes

Fleas (even one bite), environmental allergies (pollen, dust, mold), food sensitivities, dry skin, and yeast or bacterial infections.

Safe ways to relieve itching at home

Keep up flea prevention, bathe with a gentle dog shampoo, keep skin moisturized and dry, and add daily skin and coat support. Your vet can advise on antihistamines or other options.
