    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!

    My golden retriever not only loves Old Pals 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.

    My dog has IVDD, and I was looking for something to support him alongside his regular care. We've been giving him Good Stretch for about 3 months now, and I've genuinely noticed him getting stronger over that time. He seems more stable and capable than before we started. For dog parents dealing with IVDD or other back issues, I'd definitely recommend giving this a try.

    Rudy's 8 now, which makes him officially a senior. Here's how I'm monitoring his mobility: The nerves are where discomfort signals fire from. The spine is the core support for his whole body. And a healthy inflammatory response helps him recover after a big day. Good Stretch by @kinsupersupps supports all of it with 21 active ingredients I just scoop on his food. If your dog is already slowing down, this is exactly where I'd start.

    When my Aussie started limping and slowing down, I took her to the vet. Of course the usual Rx of an NSAID was given. After only 3 days on the meds, she experienced side effects and absolutely felt horrible. I immediately started researching for an alternative and landed on Good Stretch. Within a week her limp was so much better and she was back to herself!

    Hi, I have seen changes in my dog Cocoa. She has been on Old Pals 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.

    My Shiba was limping, groaning every time she sat or lay down, and hiding from the family. It was heartbreaking. After trying almost everything on the market, I read the reviews for Good Stretch and figured with the 90-day guarantee, what did I have to lose? We're 60 days in and my little girl is back to her old ways. She's playing with her boxer sister and practically running on our daily walks. Thank you for giving me my sweet girl back... I'll never take her off this!

    Our frenchie had knee surgery at 4 to fix his luxating patella. Ever since, he has been quick to limp after playing or walking a little too fast on a walk. An almost lifetime of Rimadyl and Cosequin wasn’t helping. We switched to KIN after looking at many other companies. Within weeks BMO was running and playing with minimal or no limping after! He acts younger and is more active. To see him come alive again has been amazing. He won’t eat his food without his “sprinkles”, so it must taste amazing.

    My dog was slowing down and just not his bubbly self anymore. He has a disk issue in his lower back that is not severe, but undoubtedly gives him some discomfort. He is on medication for it, but it wasnt until I started giving him Kin Good Stretch that things changed. About a month in I see my boy being silly and running around more like when he was a teenager. I was so surprised. He just seems better overall and is more willing to play and interact with the other dogs instead of sleeping all day.

    Prior to using this, my fur baby had difficulty walking and getting up. I have used several supplements including red light therapy but did not see any difference. I almost gave up and people were telling me to put my baby down. But I can’t give up on him. I have used this for 27 days, barely a month. He can now stand up and walk although there are still good days and bad days. Still not perfect but with improvement compared to other products.

    KIN has made such a noticeable difference for my dog. About a year ago, she started losing interest in the longer walks and adventures she used to love, and stiffness was clearly slowing her down. I tried quite a few joint supplements with no real improvement. Since starting it, she’s been much less stiff and, even better, actually eager to get back out for longer walks and adventures again. It’s been so nice seeing that excitement return.

    I was a bit skeptical at first and worried my very picky eater would not like this. Well I am no longer skeptical! I could see the difference it makes about a week in and he not only finishes all of his food, he actually licks the bowl. He's a fan so that makes me a fan.

    She’s only been taking this for about a month, but so far I’m really pleased with the results. She seems to have more pep in her step most days and has been noticeably more interested in playing. I think the three-month mark will give me a better idea of the full benefits, but based on what I’m seeing so far, I’m optimistic and plan to keep her on it.

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.

  • ABOUT GOOD DAYS
  • PRODUCT & INGREDIENTS

How does Good Days help my dog?

Good Days combines two formulas that support the key pillars of aging well: mind, gut, immunity, and mobility. Old Pals supports brain, immune, and gut health while Good Stretch supports joint, spine, and nerve function. When all these systems get consistent daily support, dogs show real improvements in overall quality of life.

Good Days is designed for senior dogs (7+ years). It's ideal if you're currently juggling multiple supplements, want to simplify your routine, or want proactive support that addresses aging holistically. This bundle replaces 8-10 separate bottles with two scoops.

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

Good Days addresses the root systems that affect senior wellness: mobility, digestion, cognition, and immune function. Rather than masking symptoms, we support natural processes. Every dog is unique, which is why we offer a 90-day guarantee. If you don't see improvements in movement, digestion, and overall vitality, we refund every dollar.

You’ll usually notice digestion improvements first - sometimes within a week. Structural improvements such as those in joint and mobility can take longer, building steadily over 2–3 months of consistent use. We're supporting natural processes, not masking symptoms, so sustainable improvements take time.

Why powder instead of chews?

Most chews are built like treats - 70–80% fillers to hold their shape. Powders skip the junk, keep full potency, and let you adjust dosing easily. No heat to degrade nutrients, no binders, just active ingredients you can mix into food or broth. Got a picky eater? Reach us at support@kinsupersupps.com and we’ll send you our feeding guide.

Yes. You can mix both scoops together and give them at the same time. It’s the easiest way to keep their feeding routine simple, and the formulas are designed to complement each other.

Just one: flaxseed. It keeps the powder smooth without synthetic flow agents like silicon dioxide or magnesium stearate. Flaxseed also brings omega-3s and fiber for digestion, skin, and coat.

All of our ingredients come from vetted suppliers who meet NASC requirements for quality and traceability. Our mushrooms are USDA-organic fruiting bodies, our probiotics are individual strains, not a blend, sourced from cGMP-certified facilities, and our KSM-66® Ashwagandha is the patented, clinically-studied form. Every ingredient includes safety and purity testing before they’re used.

Both Old Pals and Good Stretch are manufactured in the United States at an FDA-registered, cGMP-certified facility specializing in nutritional supplements. The facility is also NASC-certified, meeting the highest standards for pet supplement manufacturing.

A more active & comfortable
senior dog in the next 90 days.
