Does your dog constantly scratch, bite, or lick himself? As frustrating as it may be, take comfort in knowing that you're not alone in dealing with the issue and there are often things that can be done to help. One possible key: dog food.
What Causes Itchy Skin in Dogs
According to Dr. Joel Griffies, a board certified veterinary dermatologist in Marietta, Georgia, dogs are affected by many of the same allergens that affect people — environmental triggers such as pollen, molds, dust, and insects (especially fleas). Food allergies are possible, but not as common as some may think. Fortunately, there are ways to help dogs with food allergies.
What Causes Food Allergies in Dogs
"Dogs with food allergies are typically allergic to proteins, which come from animal or plant-based ingredients in the diet," says Dr. Jennifer Coates. "The proteins are broken down into molecules that the immune system misidentifies as a potential threat. Beef, dairy, wheat, and chicken are the most common culprits of food allergies in dogs. The development of food allergies, however, takes time. So the dog may have been eating the offending ingredients for quite a long time before symptoms develop."
What is the Best Food for Dogs with Allergies?
Finding the best food for a dog with allergies can be tricky and should not be done alone. Consult your veterinarian, who can help you properly conduct a food trial using a "hypoallergenic" dog food that utilizes a novel protein source or hydrolyzed protein.
"A 'novel' protein source is one that is completely new to the dog," says Dr. Coates, "thereby reducing the chance of an immune response." Hypoallergenic dog food options include venison and potato, duck and pea, salmon and potato, or even kangaroo, as long as the dog hasn’t been exposed to these ingredients in the past.
Hydrolyzed diets, meanwhile, are made when intact animal proteins are broken down into very small molecules that the immune system should not be able to recognize as allergens, virtually eliminating the possibility of an adverse food reaction. "Starches or rice are typically used as carbohydrate sources because they are very infrequently associated with allergic reactions," says Dr. Coates.
Other Skin and Coat Benefits When Using Quality Dog Food
Quality dog food is crucial to keeping dogs healthy in so many ways that it should come as little surprise that dog food also plays a vital role in keeping their skin and coat healthy — even dogs that don't suffer from food allergies. Dog food with a proper balance of omega-6 and omega-3 fatty acids, for example, will promote vibrant hair that doesn't split, break or fall out as easily. Additionally, dog foods with omega-3 fatty acids have an anti-inflammatory effect to reduce itching and other irritations caused by allergies or environmental conditions (like low humidity levels in the winter).
So why wait? Discuss with your veterinarian how diet and other means can help your itchy dog today.
