Persistent scratching, licking, or chewing isn’t just an annoying habit – for many dogs, it’s a sign of an underlying allergy.
Allergic skin disease is one of the most common reasons Irish dog owners bring their pets to the vet; and understanding what’s driving it is the first step to getting it under control.
Flea Allergy Dermatitis (FAD) is the most common type of ectoparasite allergy. Rather than the itchiness that occurs with flea infestation, this is caused by hypersensitivity to flea saliva. For this reason, your dog does not have to be visibly infested with fleas to suffer from FAD. A single bite will trigger a reaction that lasts long after the flea has finished feeding and left the skin. The best way to rule out ectoparasite allergies is to use year-round preventative treatments prescribed by your vet.
Dietary allergy involves an immune reaction to a specific ingredient in the diet. This is usually a protein source, such as beef, chicken or dairy, though grains such as wheat are also commonly implicated. Affected dogs may suffer from gastrointestinal issues as well as itchy skin. The best way to investigate a dietary allergy is with a strict eight-week diet trial (using a prescription hypoallergenic dog food obtained from your vet), followed by challenging (in a controlled fashion) with different food ingredients and monitoring your pet’s reactions.
Atopic dermatitis (atopy) is an inherited tendency to react to everyday environmental allergens such as grass, trees and pollen, house dust mites and moulds. This type of allergy is usually suspected after ectoparasite and dietary allergies have been ruled out or treated. It may be a seasonal or year-round issue, depending on the allergens involved. Some breeds are genetically predisposed to atopy, but it can occur in any dog. The diagnosis and management of atopy can be complex, and may involve blood tests, intradermal testing, and/or long-term medication.
Our vets are experienced in the diagnosis and management of allergic skin disease, and we understand how frustrating it can be for you and your pet. It is good to be prepared for this to be a step-by-step workup, and to know that treatment may take some trial and error initially. It is also worth noting that most allergies will require life-long management in one form or another. Regular vet visits allow us to get allergies under control more quickly, and to catch flare-ups early to prevent further complications and costly treatments. This is where our Pet Health Plans come in handy, as all consult fees will be covered, as well as discounts on ectoparasite treatments and any prescription diets that may be required.
If your dog is persistently itchy, our vets will start by taking a comprehensive history and performing a clinical examination. Each dog receives a tailored workup and treatment plan to fit their situation and specific skin issues. This may involve prescribing appropriate flea and tick prevention, discussing the possibility of a diet trial, performing in-house tests such as bloodwork or skin cytology, or referral to a dermatology specialist when required. We have many excellent symptomatic treatments available, such as topical shampoos and ointments as well as tablets and injections to control the itch. Visit us today to get to the bottom of your pet’s allergies and find the right treatment for him/her.
