By the end, you‘ll be equipped to make the best choice for your itchy pup. Let‘s dive in!
Understanding Dog Skin Allergies
Just like humans, dogs can suffer from a variety of allergies that manifest as skin problems. The most common are:
Flea allergy dermatitis (FAD): An allergic reaction to flea saliva, resulting in intense itchiness, red skin, scabs, and hair loss. Occurs most often around the tail base, hind legs, and belly.
Environmental allergies: Reactions to airborne allergens like pollen, mold, and dust mites. Can cause itchy skin, recurrent ear infections, and runny eyes.
Food allergies: Triggered by a sensitivity to one or more ingredients in the dog‘s diet, most commonly animal proteins. Leads to non-seasonal itching (often the ears and paws), skin and ear infections, and sometimes digestive upset.
For the purpose of this article, we‘ll be focusing on food allergies in dogs. It‘s important to note that true food allergies are much less common than people think, accounting for only about 10% of allergy cases in dogs. However, when a food allergy is to blame, choosing an appropriate diet is essential for getting relief.
What to Look for in a Hypoallergenic Dog Food
When shopping for a dog food to manage skin allergies, these are the things I advise my clients to prioritize:
Novel animal protein source: The animal protein should be one your dog hasn‘t been exposed to before, as this is the most common trigger for allergies. Good options include venison, duck, kangaroo, and fish if your dog hasn‘t eaten them in the past.
Limited ingredient formula: The fewer ingredients, the better. This reduces the chances of your dog reacting to something in the food. Avoid foods with a long list of fillers and additives.
Hydrolyzed proteins: Hydrolyzed proteins are broken down into tiny pieces that are too small for the immune system to recognize and react to. This allows many allergic dogs to eat these proteins without issues.
Grain-free or single grain: Some dogs are sensitive to grains like wheat, corn, and soy. Opting for a grain-free or single-grain formula using rice or oats instead can be helpful.
Essential fatty acids: Omega-3 and omega-6 fatty acids help nourish the skin, strengthen the skin barrier, and lower inflammation. Look for foods containing fish oil or flaxseed.
Antioxidants: Vitamin E, vitamin C, and plant antioxidants support skin health and immunity. Ingredients like berries, leafy greens, and certain herbs provide natural antioxidants.
No artificial colors, flavors or preservatives: These synthetic additives can trigger reactions in sensitive dogs. Stick to natural preservatives like mixed tocopherols instead.
Now that you know what to look for in a hypoallergenic dog food, let‘s take a closer look at some of Hill‘s top formulas for skin allergies.
Hill‘s Prescription Diet z/d
If your vet suspects a food allergy is to blame for your dog‘s itchy skin, they will likely recommend a prescription diet like Hill‘s z/d. This food contains hydrolyzed chicken liver as the protein source, which is highly digestible and unlikely to trigger an immune response. The carbohydrates come from potato starch and cellulose, making it a good option for dogs with grain sensitivities.
Additional benefits of Hill‘s z/d include:
- Boosted levels of essential fatty acids to support skin health
- Antioxidants to reduce oxidative stress and promote a healthy immune system
- S+OXSHIELD, Hill‘s unique blend of ingredients to prevent bladder stones
- Both dry and canned varieties for picky eaters
In my experience, most dogs with true chicken allergies are able to tolerate and thrive on this food. The hydrolyzed protein is a game-changer! I‘ve seen some pretty dramatic improvements in chronic skin and ear infections after switching to z/d.
The downside is that this food does require a prescription from your vet, and it is on the expensive side. However, it is a highly effective option for severe or stubborn skin allergies. Your vet will likely recommend doing a strict 8-12 week diet trial with z/d to determine if a food allergy is indeed the culprit for your dog‘s issues.
Hill‘s Prescription Diet d/d
Another popular prescription diet from Hill‘s is d/d, which comes in both potato & duck and potato & salmon formulas for dogs with suspected food sensitivities. Unlike z/d which uses hydrolyzed chicken, d/d‘s animal proteins come from novel sources that are less likely to have been included in your dog‘s previous diet.
The benefits of Hill‘s d/d include:
- Single animal protein source (duck or salmon)
- Highly digestible carbohydrates from potatoes
- Enriched with essential fatty acids for skin nourishment
- Antioxidants to support immune system health
- Dry and canned options to suit your dog‘s taste
I often reach for d/d for dogs whose symptoms aren‘t quite as severe as those who need z/d. It‘s a great option for milder itching and digestive issues that haven‘t responded to over-the-counter limited ingredient diets. Most of my patients find the taste very palatable too.
Again, this is a prescription-only formula that requires veterinary approval and oversight. The cost is comparable to z/d. I usually have owners strictly feed d/d for a minimum of 8 weeks before assessing its effectiveness for their dog‘s allergies.
Hill‘s Science Diet Sensitive Stomach & Skin
For dog owners who want to try a non-prescription option for skin issues, Hill‘s Science Diet Sensitive Stomach & Skin is my top pick. This formula focuses on gentle digestion and nourishing the skin & coat in a tasty, affordable food.
Notable features of Hill‘s Science Diet Sensitive Stomach & Skin:
- Real chicken as the #1 ingredient
- Prebiotic fiber to support digestive health & regularity
- Vitamin E, omega-6 fatty acids, and other nutrients for skin & coat health
- No artificial colors, flavors, or preservatives
- Available in both dry food and canned stew for variety
While this formula isn‘t quite as specialized as the prescription diets, I‘ve found it to be an excellent choice for dogs with milder itching, dandruff, or a dull coat, as well as those with some digestive sensitivities. The chicken and rice recipe is usually well-tolerated, and the skin-supporting nutrients can make a noticeable difference.
This food is also much easier on the wallet compared to the prescription diets, and you can buy it without vet approval. Of course, I always recommend talking to your own vet before making a major diet change. But if you‘re looking for a science-backed sensitive skin formula you can pick up at the pet store, this is an excellent option to try.
Tips for Transitioning Your Dog to a New Food
Whenever you switch your dog to a new food, it‘s important to make the change gradual to avoid digestive upset. Here‘s how I advise my clients to transition:
- Days 1-3: Serve 25% new food mixed with 75% old food
- Days 4-6: Serve 50% new food mixed with 50% old food
- Days 7-9: Serve 75% new food mixed with 25% old food
- Day 10: Serve 100% new food
If at any point your dog develops vomiting or diarrhea, go back to the previous ratio and proceed more slowly. For dogs with very sensitive stomachs, you may need to stretch the transition over 2-3 weeks.
It‘s also crucial to resist the temptation to slip your dog other foods during a diet trial for suspected allergies. That means no table scraps, special treats, rawhide chews, or flavored medications. Work with your vet on acceptable treats or alternatives.
When to See Your Vet
Skin allergies can make your dog miserably itchy and uncomfortable, so it‘s important to involve your veterinarian early on. Make an appointment with your vet if you notice:
- Frequent or intense scratching, licking, chewing or rubbing
- Red, scaly, or greasy patches of skin
- Stinky odor from the skin or ears
- Hair loss or bald spots
- Recurrent ear or skin infections
While a diet change can certainly help, some dogs may also need medications like antihistamines, steroids, antibiotics, or anti-itch sprays to get their symptoms under control. Flea control and treatment for any secondary infections are also key. Your vet can help you develop a comprehensive treatment plan to address all aspects of your dog‘s allergies.
Other Tips for Managing Dog Skin Allergies
In addition to choosing a high-quality, allergy-friendly dog food, here are some other ways you can support your itchy pup:
- Supplement with omega-3 fish oil for an extra boost of skin-nourishing fats
- Use a gentle, moisturizing dog shampoo to soothe irritated skin and restore the skin barrier
- Ask your vet about anti-itch sprays, mousses, and wipes to "spot treat" problem areas
- Run a humidifier in your home to prevent dry skin
- Vacuum and clean your home regularly to minimize dust, dander, and pollen
- Consider investing in a food sensitivity test to identify ingredients your dog may be reacting to
Of course, the right combination of approaches will depend on the underlying cause of your dog‘s skin issues and their individual needs. Your vet can guide you in creating a personalized care plan.
Success Stories
To wrap up, I want to share a few success stories from my own clients who have seen amazing improvements with Hill‘s allergy formulas:
"My lab mix, Charlie, was chewing himself raw and had constant ear infections. We tried every over-the-counter food out there with no luck. Finally, our vet put him on Hill‘s d/d duck and potato, and within a few weeks, his skin was clearing up and his ears were healthy again. We stuck with it, and a year later, his coat is the softest it‘s ever been!" – Sarah K.
"I was skeptical about a prescription diet, but I was desperate to help my little terrier‘s horrible itching and scabbing. Our vet recommended Hill‘s z/d, and I‘m so glad we gave it a try. The change wasn‘t overnight, but after a couple months, we noticed her scratching way less and her skin looking so much healthier. She loves the canned food mixed with the dry kibble, and we love seeing her comfortable in her skin again." – Jenna P.
"We thought our golden retriever would need to be on medication forever for his skin allergies, but switching to Hill‘s Science Diet Sensitive Stomach & Skin has been life-changing. Not only is his coat shiny and itch-free, but his digestion is so much better too. No more upset stomach or loose stools. We‘re so grateful to have found an affordable food that keeps him healthy and happy." – Mike T.
