Why Is My Dog Itching UK?
By Kaiser Khan, EditorPublished Last updated 2 min read
Quick answer
Persistent itching usually means flea allergy, environmental allergens, or food proteins — not just "dry skin." Year-round flea prevention is the first step. If itching continues, your vet can identify triggers and prescribe effective anti-itch treatment rather than endless bathing or random diet changes.
Key takeaways
- Itchy skin — especially paws, belly, ears, and face — recurrent ear infections, licking paws, hair loss, and red or inflamed skin are typical. Some dogs also have digestive signs with food allergies.
- Yes. Flea allergy dermatitis can cause intense itch from a single bite. Year-round flea prevention is essential — fleas are easy to miss on dark-coated dogs.
- An elimination diet trial — feeding a novel or hydrolysed protein for eight to twelve weeks with no other food or treats — is the most reliable method.

Three main causes
Flea allergy dermatitis
Even one flea bite can trigger intense itching in sensitised dogs. Use year-round flea prevention on all pets in the household — skipping months allows reinfestation.
Environmental allergies (atopic dermatitis)
Pollen, house dust mites, and mould cause seasonal or year-round itch — especially paws, belly, ears, and face. Management combines allergen reduction, regular bathing, and prescription medications.
Food allergies
Protein sources in the diet trigger itch and sometimes digestive signs. An elimination diet trial under vet guidance is the only reliable diagnostic method.
Other causes of itch
- Ear infections — head shaking, smelly ears, pawing at ears
- Mange (mites) — especially in puppies or immunocompromised dogs
- Contact irritation — new bedding, floor cleaners, or plants
- Yeast or bacterial skin infection — secondary to underlying allergy
What helps at home
- Consistent flea treatment on all household pets
- Regular grooming to spot hot spots early
- Avoid frequent bathing with harsh shampoos — this can worsen dry skin
- Do not give human antihistamines without vet dose confirmation
When to call your vet
Book an appointment if itching affects quality of life, causes broken skin, or persists despite flea control. Recurrent ear infections almost always need investigation for underlying allergy.
