Dogs may develop a variety of signs, described above, depending upon the severity of their allergy.Some cases are related to dietary allergens. This syndrome is called cutaneous adverse food reaction (CAFR). These dogs may develop an allergy to a food they have been eating for some time, or may recently have been changed onto a new food, which triggers the onset of signs.How can you help your dog?If your dog has any of the signs above, it is very important to have a consultation with a vet to rule out other causes of itching, such as fleas, mites or ringworm. They may suggest skin scrapes or other tests to investigate the cause. If your vet is suspicious of allergy, they may advise a skin biopsy to gather further information. However, many cases of allergic dermatitis are treated based on the clinical signs and presumptive diagnosis alone. It will depend on your pets history, signs and the progression of their illness. If your pet has been diagnosed with allergic skin disease, the next step is to work out whether the signs are due to an environmental or food allergen. Your pet may be allergic to one or more allergens at the same time, and this can make diagnosis more complicated.Diagnosing and treating cutaneous adverse food reactionYour vet may firstly recommend an elimination diet to exclude cutaneous adverse food reaction. Elimination diets typically require 6-8 weeks to complete, and close monitoring to ensure that your dog does not eat anything other than their allocated food ration and water throughout the trial. Please follow the link to our article, which will help to guide you through the process.Diagnosing and treating environmental skin allergiesThe most common causes of environmental allergies are pollen, flea saliva and dust mites. Signs are often seasonal due to varying levels of exposure to seasonal allergens, such as tree pollen. We can’t eliminate many of these allergens from your pets' environment. Instead, we must target our approach to managing the signs associated with exposure. Treatment usually requires medication, which is designed to reduce the inflammatory response, reduce inflammation and therefore control the itching. Other measures, such as bathing in soothing oatmeal pet shampoo and feeding essential fatty acid supplements, may also be beneficial in long term management.What is allergen specific immunotherapy (ASIT)?Allergen specific immunotherapy is a course of injections given once a month over an extended period of time (often months to years). The purpose of these injections is to relieve the signs of the allergy. To start, your pet will need to have blood taken to test against a wide range of allergens. If your pet has antibodies against any of these allergens, it will give a positive result. The results can then be used to make an individual vaccine, specifically tailored to your pet. This vaccine contains small amounts of the allergens, which your pet has tested positive for. The vaccine injections deliver very small doses of these allergens to your pet, with the aim of decreasing their sensitivity and reducing the immune response to them.When to see your physical vetIf your dog is showing any of the symptoms listed aboveStill worried?Book a video appointment to have a chat with one of our vets.
