    My golden retriever not only loves this on her food but has improved shine to her coat, less shedding. Took the place of other supplements by having everything in one and better quality ingredients. Fast on time shipping with the subscription.

    If you’ve been here for five minutes, you already know a supplement brand does not make it onto my page simply because they sent me a jar. I read the entire label. I research the ingredients, their forms and their amounts. I look for unnecessary fillers, vague blends, quality testing and whether the formula makes sense as a whole. KIN Super Supps went through that process and earned a place in Kodiak’s routine for life.

    Hi, I have seen changes in my dog Cocoa. She has been on this for a little over one month. Before, starting this she was pacing at night. The pacing has stopped. She is back to sleeping through the night again. Cocoa is almost 17 years old. Thank you so much for this product.

    As a dog nutritionist, I pay close attention to loose stools, itchy skin and low energy in senior dogs.

    That's why, now that Rudy's officially a senior, I started him on Old Pals by @kinsupersupps.

    It’s an advanced probiotic & daily vitality formula for senior dogs with 25 active ingredients to support a balanced gut, a stronger immune system and sharper cognitive function, in one scoop.

    ✅ GUT: 27 billion CFU of probiotics + prebiotics
    ✅ IMMUNE: Chaga, cordyceps, turkey tail & reishi mushrooms
    ✅ BRAIN: MCT, lion’s mane & ashwagandha

    Our chocolate lab, Jasper, is turning 12 and never bounced back to who he was before surgery. It broke our hearts to see him so down for months. We tried multiple supplements before finding Good Stretch and Old Pals. WOW! Just one week in, he started playing with toys that had sat untouched in the basket for months. He has light back in his eyes, excitedly follows me around again, and is back to his spunky, sneaky self instead of hiding away. This truly gave him his spark back!

    I am still giving Old Pals to my dog Bear who is 15yrs and I see a good sign of calmness after panting a little too much, so now he sits still and is alert and sleeps better...  I think its a combo of other supplements he's taking too.

    BETTER DIGESTION

    Poops and appetite get better first as the beneficial bacteria start working in your dog’s gut. This is usually the first thing parents notice.

  • Tag

    STRONGER IMMUNITY

    Most of your dog's immune system sits in the gut, so as the gut settles, their immune system gets stronger and less reactive to seasonal changes.

  • Tag

    MORE ALERT

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

  • Tag

    HEALTHIER SKIN

    Skin takes the longest, because the gut and immune system need to be rebuilt ground up. This is where you'll notice less gnawing at the paws and less restless scratching.

    BALD PATCHES

    Luna was stuck in a cone for 4 years with raw skin on her belly and sides, constantly scratching and chewing. Medicated shampoos and creams calmed it for a week or two, but the itch always came back worse.

  • Tag

    GUT & IMMUNE REBUILD

    A microbiome test showed her gut balance was out of whack. She needed probiotics and a prebiotic to rebuild the gut, and mushrooms like Reishi and Turkey Tail to calm the immune system driving the flares. By week six, her fur was starting to fill in.

GOOD DAYS GUARANTEE

GOOD DAYS GUARANTEE

Most supplement guarantees give you 30 days. That's barely enough time for the ingredients to build up in your dog's system for real changes.

That’s why we offer a 90-day money-back guarantee instead. Because real improvements in their quality of life take consistency - and you deserve to see that process happen, risk-free.

If you don't see noticeable improvements within 90 days, we'll refund every cent.
No return needed.

How long before I see results?

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 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.

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.

What ingredients are in Old Pals and why were they chosen?

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.

A healthier senior dog in 90 days,
or your money back.
