8 Foods That Help Fight Your Dog’s Itchy Skin From the Inside Out

MidJourney

If your dog won’t stop scratching, it might be more than just dry skin. Many dogs suffer from itchiness caused by internal inflammation, allergies, or poor nutrition. The right foods can help soothe your dog’s skin by supporting digestion, reducing inflammation, and strengthening their skin barrier from within. Here are eight options that can make a noticeable difference.

Salmon is rich in omega-3 fatty acids, especially EPA and DHA, which are known to calm inflammation. These fats help moisturize your dog’s skin and reduce itchiness caused by allergies. If you’re not feeding fresh fish regularly, adding an omega-3 supplement is a smart move. One option is iHeartDogs Norweigan High Omega-3 Salmon Oil (on Amazon), which offers a concentrated source of these essential fats.

Bone broth isn’t just trendy for humans—it’s a powerful skin-supporting food for dogs too. It’s packed with amino acids like glycine and proline, which help repair skin and gut tissues. It also delivers hydration and collagen, both important for dogs suffering from dry, flaky skin. Try Organic Chicken Bone Broth Powder (on Amazon) as a topper to make meals more appealing while helping soothe irritation from the inside.

Blueberries

Blueberries are loaded with antioxidants that protect cells from damage caused by inflammation and environmental stress. These berries support immune health, which is critical for dogs prone to skin allergies. You can find them already mixed into easy-to-use toppers like the Beef Topper with Carrots and Blueberries (on Amazon), which combines real meat with antioxidant-rich produce.

Pumpkin

Pumpkin is a gentle, fiber-rich food that supports digestion. A healthy gut is often the key to managing skin conditions in dogs since many allergies begin in the digestive system. When your dog’s digestion is off, it can show up as itching, hot spots, or rashes. Pupkin Probiotics and Prebiotics with Pumpkin For Dogs (on Amazon) are a tasty, simple way to keep your dog’s gut in check, which can lead to calmer skin.

Sweet Potatoes

Sweet potatoes are a hypoallergenic source of complex carbohydrates that help fuel your dog without triggering common food allergies. They’re rich in beta-carotene, which the body converts into vitamin A—a nutrient critical for maintaining healthy skin and tissue regeneration. Baked or steamed sweet potatoes are an easy addition to your dog’s bowl.

Collagen

Collagen is a structural protein that makes up much of your dog’s skin, joints, and connective tissue. Supplementing with collagen can improve skin elasticity and help repair damage from scratching or hot spots. The Beef Topper with Collagen (on Amazon) is an easy way to sneak in collagen without any extra prep.

Sardines

Canned sardines (in water, no salt) are a nutrient-dense option that’s high in omega-3s, vitamin D, and protein. These tiny fish support skin hydration, reduce inflammation, and even help with coat shine. Because of their size and softness, sardines are easy to feed whole as a treat or mix into meals.

Coconut Oil

Coconut oil can help both topically and when added to food. It contains lauric acid, a fatty acid known for its anti-inflammatory and antibacterial properties. A small amount in your dog’s meals can support skin healing from the inside, especially for those with flakiness or minor bacterial skin infections. Just be sure to introduce it gradually to avoid digestive upset.

Try Food First to Soothe Your Dog’s Skin

Skin issues are often a sign that something deeper is going on in your dog’s body. These foods and supplements work best when used regularly, as part of a consistent diet focused on gut health and inflammation control. Always check with your vet before introducing new supplements, especially if your dog has food allergies or is on medication.
