Clients complaining about their pet itching while the family loses sleep?
Skin disorders, including allergic skin disease, are a common reason owners bring their pets to the vet. Allergies in pets affect quality of life for not only the pet, but the pet owners as well – impacting the human-animal bond. Pruritic (itchy) pets are often uncomfortable, leaving owners to determine the reason for the itching and what can be done to stop the itch. Common skin allergies diagnosed in dogs and cats are fleas, atopy (environmental allergies), and food.1
Veterinary Nurses play a key role
Nutrition plays a key role in the management and treatment of skin disorders, including adverse reactions to food and environmental allergies. Veterinary nurses have an important role in managing dermatological conditions and improving patient care through two main evenues: client communication and enhanced compliance. In fact, the veterinary nurse is the key interface between the veterinarian and the client, reinforcing the veterinarian’s recommendation and supporting the client.
Allergens in the environment
Common allergens that our pets are allergic to our dust mites, mould and pollens and many are ubiquitous in the environment. Atopy is an inherited disorder caused by a dermal barrier defect. Allergens penetrate the skin, which subsequently stimulates the immune system. This immunologic response results in the release of inflammatory mediators and causes an inflammatory cascade which tends to worsen each subsequent season.
Diagnosis for atopy can be complex and involves eliminating other conditions with similar symptoms. It is important to ensure appropriate control for external parasites is used, and potentially food elimination trials may need to be done. The nutritional history is of utmost importance when diagnosing and managing atopy and the veterinary nurse leads this history taking.
Adverse reactions to food (AFR)
Adverse reactions to food are not easy to diagnose as they frequently imitate other, more common allergic diseases such as atopy. An adverse reaction to food is an abnormal response to an ingested food or food additive. Adverse food reactions typically occur as non-seasonal pruritic dermatitis, occasionally accompanied by gastrointestinal signs. In dogs, adverse reactions to food make up around 10-20% of allergic skin disease in dogs and is conceivably as common as atopic dermatitis in cats. 5
A complete nutritional history by the veterinary nurse should determine the quality and adequacy of the food being fed to the pet, the feeding protocol, and a thorough history of the types of foods fed, including access to treats, supplements, and/or other foods (including another pet’s food). Ask open ended questions to stimulate conversation with the owner. A proper nutritional history for suspected derm cases will result in uncovering the following:
- Specific foods pet ingests
- Commercial snacks or treats
- Chewable medications
- Chew toys
- Human foods
- Access to other sources of food
- Other pets in the home
Nutritional history – The Nurse’s Role
The pet owner should maintain a diary for several weeks prior to the visit and document the types of food and other items the pet ingests daily. The patient’s nutritional history should be reviewed carefully for allergens or ingredients believed to be commonly associated with or at risk of exacerbating skin disorders.
The nutritional status of the animal will affect the health of the skin and veterinary nurses are responsible for educating owners regarding how this happens and what nutrients are involved.
Nutrition plays a primary role in the management and treatment of skin disorders and research has demonstrated that the use of dietary fatty acids, antioxidants, novel proteins, and hydrolysed proteins are beneficial in the management of inflammatory skin diseases and adverse food reactions.
A complete nutritional package
Recently, Hill’s introduced a therapeutic nutritional solution aimed at supporting dogs with a broad range of inflammatory skin conditions including environmental and food allergies.. It contains high levels of essential fatty acids to help strengthen the skin barrier and Histaguard Complex – a blend of bioactives and phytonutrients to help normalise the immune system reaction to environmental allergens. The protein source is egg – a single high-quality intact animal protein that avoids 96% of food allergies.
In a clinical study, veterinarians reported visible skin healing in as little as 21 days8. In another study owners reported less scratching and improved sleep quality in their dogs and in their own sleep!9
This food can complement your multi-modal approach to managing skin disorders.
Now veterinary nurses can help patients and owners strengthen the human animal bond that began to fray with skin disorder symptoms – all through the power of nutrition.
