Immune boosters for dogs

Immune boosters for dogs - natural protection, every day

Is your dog getting sick more often, recovering slowly, or feeling low on energy? Then it might be time for immune support for dogs – especially if your pet is a senior, has allergies, or is bouncing back after illness or surgery.

On this page, you'll find carefully selected dog immune supplements with science-backed ingredients like turkey tail mushroom for dogs and colostrum for dogs. These natural ingredients help boost resilience, support recovery, and strengthen immunity - safely and gently.

Why choose a natural immune support formula?

Medicinal mushrooms like reishi for dogs, shiitake, maitake, cordyceps, and turkey tail are more than immune stimulants. They protect cells, reduce inflammation, and help increase your dog's immune system naturally - without synthetic additives or harsh chemicals.

Meanwhile, colostrum provides key antibodies and growth factors that repair the gut, reduce allergies, and enhance overall immune balance - especially for puppies and dogs with chronic inflammation.

When does your dog need immune support?

• Gets sick frequently or takes longer to recover
• Suffers from skin issues, allergies, or chronic inflammation
• Is a puppy with a developing immune system
• Is an older dog with reduced vitality or energy
• Is undergoing cancer treatment or recovering from surgery

The right immune booster doesn’t just protect - it helps your dog heal, stay strong, and thrive at every stage of life.
