What is skin allergies (atopic dermatitis)?

Canine atopic dermatitis is a chronic, inherited skin condition caused by an overactive immune response to environmental allergens such as pollen, dust mites, and mould spores. It is the second most common allergic skin disease in dogs after flea allergy dermatitis and typically develops between 1 and 3 years of age. Affected dogs suffer persistent itching, redness, and recurrent skin and ear infections. While atopic dermatitis cannot be cured, most dogs can be kept comfortable with ongoing management, though this can be expensive over a lifetime.

Symptoms to watch for

See a vet soon

Persistent scratching, licking, or chewing at the skin
Red, inflamed skin, especially on the belly, paws, and ears
Recurrent ear infections
Hair loss from excessive scratching or licking
Thickened, darkened skin in chronically affected areas
Hot spots (acute moist dermatitis)
Watery eyes or sneezing in some dogs
Musty or yeasty smell from skin or ears

How is skin allergies (atopic dermatitis) diagnosed?

Test	Typical cost
Dermatology consultation and clinical history	£35–£65
Skin scraping and cytology	£50–£150
Blood tests (allergy panel / intradermal skin testing)	£200–£400

Treatment options and costs

Apoquel (oclacitinib) tablets

£50–£120 per month ongoing

A daily tablet that targets the itch pathway to provide rapid relief from allergic itching. Works within 4–24 hours and is widely used for long-term management. Requires periodic blood monitoring. Cost depends on the dog's size.

Cytopoint (lokivetmab) injections

£60–£120 per injection every 4–8 weeks

A monoclonal antibody injection that neutralises the protein responsible for triggering itch. Given at the vet practice every 4–8 weeks. Well tolerated with very few side effects. Particularly useful for dogs that are difficult to tablet or cannot tolerate Apoquel.

Immunotherapy (desensitisation)

£500–£1,000 initial course, then £30–£60 per month

Customised allergen extracts are administered by injection or sublingual drops to gradually train the immune system to tolerate specific allergens. Takes 6–12 months to see full benefit and works well in about 60–70% of dogs. The only treatment that addresses the underlying cause rather than just managing symptoms.

Does pet insurance cover skin allergies (atopic dermatitis)?

Skin allergies are one of the most frequently claimed conditions in UK pet insurance, and also one of the most expensive over a dog's lifetime because treatment is ongoing. Lifetime policies typically cover allergy medication, diagnostic testing, and specialist dermatology consultations. However, time-limited policies (which cap at 12 months per condition) are particularly unsuitable for allergies as the condition is lifelong. Some insurers exclude allergies diagnosed within the first few months of cover. Given that lifetime allergy costs can reach £20,000–£40,000, choosing a lifetime policy with adequate annual limits is strongly recommended for at-risk breeds.

Frequently asked questions

How much does it cost to treat skin allergies in dogs over their lifetime?

Skin allergies are one of the most expensive chronic conditions in dogs. Monthly medication costs £50–£300 depending on the treatment, and most dogs need lifelong management. Over a 10-year period, total costs can easily reach £15,000–£40,000 when you include medication, special diets, medicated shampoos, and periodic flare-ups requiring additional treatment.

What is the difference between Apoquel and Cytopoint?

Apoquel is a daily tablet that blocks the itch signal inside cells, while Cytopoint is a monthly injection that neutralises the itch-triggering protein outside cells. Both are effective, but Cytopoint has fewer potential side effects and is useful for dogs that are hard to tablet. Some dogs respond better to one than the other. Your vet can help you decide which is most appropriate.

Can dog allergies be cured?

Atopic dermatitis cannot be cured, but it can usually be well managed. Immunotherapy (desensitisation) is the only treatment that can modify the underlying immune response, and it is effective in about 60–70% of dogs, sometimes reducing or eliminating the need for other medication. Most dogs need some form of ongoing management throughout their lives.

Are food allergies the same as skin allergies?

No, though they can look similar. Environmental allergies (atopic dermatitis) are caused by airborne allergens like pollen and dust mites, while food allergies are caused by specific proteins in the diet. Food allergies account for only about 10–15% of allergic skin disease in dogs. A strict elimination diet trial over 8–12 weeks is needed to diagnose food allergy. Many dogs have both environmental and food allergies.
