ISN'T BETTER

Maybe you're giving your senior dog a probiotic. Or a mushroom supplement. Or fish oil. Juggling separate bottles for separate problems.

But here's the thing - gut, immune, and cognitive health don't work separately. They're connected, and are what matters most as dogs age.

Old Pals supports all three in one scoop without the hassle of multiple bottles or guessing what's working.

GUT – BRAIN

GUT – BRAIN

Ever notice your senior dog get more agitated when their stomach's not feeling great? That's not a coincidence. Their gut has more nerve cells than their spinal cord and it talks directly to their brain. Fix the gut and calm behavior follows.

GUT – IMMUNE

GUT – IMMUNE

70% of your dog's immune system lives in their gut. When digestion is off, immunity drops. When immunity is weak, the gut struggles. Old Pals supports both at once.

BRAIN – IMMUNE

BRAIN – IMMUNE

Chronic stress weakens immunity. A calmer dog is a healthier dog - and reduced inflammation protects brain tissue from age-related decline.

  • Tag

    DIGESTION FIRST

    Poops get better first. More solid, less gas. That's the beneficial bacteria settling into your dog’s gut.

  • Tag

    CALM BEHAVIOR

    After 2 to 4 weeks of consistent feeding, you might notice less pacing. They settle into their spot easier or seem more at ease.

  • Tag

    CLEAR MIND

    This is when people usually notice something's different. Longer eye contact. More engagement. Some dogs may start playing more like they used to.

  • Tag

    NEW NORMAL

    This is now the new normal. Not a puppy again - but healthier. More present. More good days than bad.

  • ABOUT OLD PALS
  • PRODUCT & INGREDIENTS

Old Pals is designed to support the areas that matter most as dogs age: gut health, immune balance, and cognitive function. It's a blend of probiotics, fruiting-body mushrooms, antioxidants, and vitamins and minerals that help maintain comfort and vitality in senior dogs.

Every dog is different but many pet parents notice early signs like digestive improvements (firmer stools, less gas) within 1-2 weeks. Behavioral changes (calmer demeanor, better engagement) can take up to 4 weeks. Immune and cognitive benefits develop over 8-12 weeks. We're supporting natural processes, not masking symptoms, so sustainable improvements take time.

Old Pals is formulated with senior dogs in mind, but it's safe for adult dogs too. Puppies under 12 months should only use it under the guidance of a veterinarian to ensure it meets their developmental needs.

We recommend checking with your veterinarian before adding any new supplement if your dog is taking medication or has an existing medical condition. Because Old Pals contains prebiotic fibers, it may delay the absorption of drugs taken at the same time. Old Pals can generally be given alongside most medications, but timing matters for probiotics. If your dog is on antibiotics, giving Old Pals about 2 hours apart may help maintain probiotic activity. For steroids or other long-term medications, your veterinarian can help you decide the best timing and routine for your dog.

Old Pals uses ingredients with a purpose: clinically studied ingredients such as the use of 10 individual probiotic strains (instead of a blend), real fruiting-body mushrooms, and ingredients such as milk thistle, and organic broccoli sprout for liver support, as well as antioxidants to support healthy aging.

Yes, they can consume certain mushrooms when they are the right species and properly prepared. Old Pals uses fruiting-body extracts from well-studied varieties like Reishi, Lion’s Mane, Turkey Tail, Cordyceps, and Chaga. These mushrooms are known for immune and cellular support and are suitable for daily use. If your dog is taking medications that affect immune function, check with your veterinarian before adding mushroom-based supplements.

These ingredients offer gentle daily support for dogs, especially seniors. Acerola Cherry provides natural vitamin C to help maintain cellular health and overall vitality. Milk Thistle is widely used for its supportive role in normal liver function. Organic Broccoli Sprout is a source of sulforaphane that provides antioxidant support. Together, they offer extra support to help keep your dog feeling good as they grow older.
