Allergy testing for dogs starts at £29.99 and delivers results within 5 days. By identifying specific allergens, you can make informed changes that greatly improve your dog's quality of life, alleviating discomfort and promoting better health and happiness.
It's estimated up to 33% of all dogs suffer from a food allergy. These allergies can manifest in a variety of symptoms, from persistent itching and skin irritation to chronic ear infections and gastrointestinal disturbances. Recognising and effectively managing these allergic reactions is paramount to ensuring the wellbeing and comfort of our canine companions.
As dog owners become increasingly aware of the impact of allergies on their pets' quality of life, the question of whether allergy testing is a worthwhile investment arises. Allergy testing can provide precise identification of specific allergens, enabling targeted treatment plans. However, the decision involves weighing several factors, including cost, accuracy, and the potential benefits to the pet's health.
This article explores the various methods of allergy testing available for dogs, evaluates their efficacy, and discusses the pros and cons of each. By examining both veterinary and at-home testing options, we hope to help pet owners make informed decisions about managing their dog's allergies.

Understanding Dog Allergies
Types of allergies. Dog allergies can be broadly categorised into three main types: environmental allergies, food allergies, and contact allergies.
Environmental allergies: typically caused by airborne allergens such as pollen, dust mites, mould spores, and dander. Dogs may also react to certain grasses, trees, and weeds. Symptoms often include itching, sneezing, runny eyes, and chronic ear infections.
Food allergies: occur when a dog's immune system reacts adversely to specific proteins in their diet. Common allergens include beef, chicken, dairy, eggs, soy, and wheat. Symptoms can range from gastrointestinal issues like vomiting and diarrhoea to skin problems such as itching, redness, and hives.
Contact allergies: arise when a dog's skin comes into direct contact with an allergen, such as shampoos, bedding materials, certain grasses, and household chemicals. Symptoms are typically localised to the area of contact and may include itching, redness, and swelling.
Common allergens include:
- Pollen: from trees, grasses, and weeds.
- Dust mites: often found in household dust.
- Mould spores: present in damp environments.
- Food ingredients: such as chicken, beef, dairy, wheat, and soy.
- Fleas: proteins in flea saliva can cause severe allergic reactions.
Symptoms of allergies can vary depending on the type and the individual dog's response:
- Itching and scratching: persistent and intense, often leading to secondary infections.
- Red, inflamed skin: particularly on the paws, face, and belly.
- Ear infections: recurrent, may cause head shaking and ear scratching.
- Gastrointestinal issues: including vomiting, diarrhoea, and flatulence.
- Respiratory symptoms: such as sneezing, coughing, and nasal discharge.
- Behavioural changes: increased restlessness, irritability, and discomfort.
Methods of Allergy Testing
Intradermal allergy testing. Considered the gold standard for diagnosing environmental allergies, this involves injecting small amounts of common allergens into a shaved area of skin, usually on the side or abdomen. The dog is typically sedated to minimise discomfort and movement. After around 20 minutes, the injection sites are checked for reactions such as redness and swelling, indicating a positive response.
- Pros: high accuracy in identifying specific environmental allergens, which can guide targeted immunotherapy.
- Cons: requires sedation, which carries some risk, and a specialist vet to administer and interpret. Can be expensive and inconvenient, particularly for owners without easy access to a veterinary dermatologist.
Serum allergy testing. This involves drawing a blood sample and sending it to a lab, where it's tested for antibodies against various allergens, covering a wide range of environmental and, to some extent, food allergens.
- Pros: less invasive than intradermal testing, no sedation or shaving needed. Any general vet can perform it, making it more accessible.
- Cons: may produce false positives and is less accurate than intradermal testing. The correlation between blood test results and clinical symptoms isn't always consistent.
At-home saliva and hair sample testing. Pet owners collect a sample of their dog's saliva or hair and send it to the testing company's lab, where it's analysed for sensitivities or intolerances to various food and environmental factors.
- Pros: convenient and non-invasive, done at home without a vet visit. Results are typically provided within weeks via email.
- Cons: these tests look for sensitivities rather than confirmed allergic reactions. A detected sensitivity doesn't necessarily mean a true allergy is present — but the recommended next step is usually the same either way: eliminating that item from your dog's diet or environment and monitoring for improvement.
Accessibility & Cost Effectiveness
- Accessibility: at-home kits offer the highest convenience, followed by serum testing, which any general vet can perform. Intradermal testing requires access to a veterinary dermatologist, not always readily available.
- Cost: at-home tests are significantly less expensive than professional vet-administered options.
Understanding the methods available helps pet owners choose the most appropriate and effective option for their dog. The next section looks at the specific costs involved.
Costs of Allergy Testing
Intradermal testing. Known for its accuracy, this is also the most expensive option, typically costing between £400 and £800 depending on location and clinic, including sedation, test administration, and interpretation by a veterinary dermatologist. Follow-up treatments, such as immunotherapy (regular injections or oral medication), can add £80–£200 per month.
Serum allergy testing. Less invasive and more affordable, generally ranging from £240 to £400, covering the blood draw, lab analysis, and interpretation. Ongoing treatment costs, including medication or dietary adjustments, can add another £40–£160 per month.
At-home allergy testing kits. The most budget-friendly option — our tests start from £29.99, including testing materials, lab analysis, and results delivered via email.
Deciding whether allergy testing is worth it for your dog involves weighing the benefits and drawbacks against the severity of symptoms, your budget, and available resources. Professional testing methods offer high accuracy and detailed insight but come at a higher cost and require access to specialised care. At-home testing kits provide a more affordable, convenient option, but may lack the precision of professional tests.
Ultimately, the decision should be made with careful consideration, seeking expert guidance if necessary, to develop an effective, personalised plan for managing your dog's allergies.
