    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 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.

    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.

    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!

    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!

    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.

    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.

    LESS HESITATION

    You'll probably notice less hesitation in movement first - things like more willingness to take the stairs. Nothing huge, just small stuff that makes you go "huh, that's better."

  • Tag

    MORE ENERGY

    Small but meaningful changes start. They have an easier time getting up and walks can start going longer. 

  • Tag

    MORE PLAYFUL

    This is usually when people really notice something's changed. More interested in their toys. More enthusiastic when it's time to play. Movement looks easier.

  • Tag

    MORE COMFORT

    This is the new normal. Steadier movement, more energy day to day. You might notice stuff they'd stopped doing start coming back, like hopping on the couch or initiating play.

THE KIN
DIFFERENCE

THE KIN DIFFERENCE

Hydrolyzed instead of regular collagen.

Broken down for better bioavailability and gentler for dogs with sensitivities.

Boswellia standardized to 60% AKBA.

AKBA is the active compound in boswellia, and 60% is the gold standard for potency.

Turmeric standardized to 95% curcumin.

Curcumin is hard to absorb, so we use a high-potency extract paired with BioPerine® (black pepper) to boost absorption.

Patented B Vitamins

A patented form of Vitamin B from organic quinoa sprouts, 100x more concentrated than from whole grains.

Natural Vitamin C & D

Natural Vitamin C from Acerola Cherry and VegD3® from lichen instead of synthetic vitamins.

Highly-bioavailable Magnesium & Zinc

Magnesium Citrate and Zinc Picolinate, instead of the generic oxides most formulas use.

    A TORN CCL

    Bruce tore his Cranial Cruciate Ligament (CCL) at 8 years old - hopping on one foot, unable to put any weight on the injured leg. Surgery and a few screws repaired the knee, but that was just the start of getting him back.

  • Tag

    WALKING AGAIN

    His comeback needed more than joint support. Collagen and Glucosamine to cushion the joints, B-vitamins and Magnesium to stabilize the spine, Boswellia and Curcumin for inflammatory balance, and PEA for nerve comfort. By week four, he was walking again.

    RUNNING AGAIN

    Eight weeks in, Bruce was running on the beach again. He's 10 now, and Good Stretch is still part of his daily routine - supporting his joints, nerves, spine and inflammatory response to keep him moving like a dog years younger.

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 dog parents notice early signs of improvement within 2–4 weeks; things like more comfort during movement, or an easier time getting up from rest. More noticeable mobility improvements appear around 6–8 weeks with consistent daily use.

From what customers report, most picky dogs have no issues taking to Good Stretch. To help them adjust more easily, start with half the daily amount and work your way up to the full serving.

Good Stretch is formulated to be gentle, and we use hydrolyzed collagen (broken down for easier digestion). If your dog has a sensitive tummy, start with half the daily serving for the first week, then work up to the full amount to give their system time to adjust.

Most dogs take Good Stretch alongside their medication without any issues, but we always recommend checking with your veterinarian first - especially if your dog is on multiple long term medications.

Good Stretch is formulated with adult and senior dogs in mind. Puppies under 12 months should only use it under the guidance of a veterinarian to ensure it meets their developmental needs.

Good Stretch isn’t intended to treat or prevent medical conditions. It’s designed to support overall joint, spine and nerve health.

Good Stretch is formulated to support your dog’s joints, spine and nervous system. Its key ingredients are Hydrolyzed Collagen Types I and II, Glucosamine, Chondroitin, NZ Green Lipped Mussels and Palmitoylethanolamide (PEA) to help maintain healthy cartilage, normal inflammatory responses and designed for dogs who need dependable mobility support at any age.

What is Hydrolyzed Type I & II Collagen - and what if my dog has food allergies?

Type I and II Collagen support the structure of your dog’s joints, cartilage, and connective tissues. Hydrolyzed Collagen is collagen that’s been broken down into tiny peptides so it’s easier for the body to use and typically less reactive than whole proteins. Our collagen comes from bovine and avian sources, so if your dog has known sensitivities, it’s best to review the ingredient list with your veterinarian before starting any new supplement.

PEA is a naturally occurring fatty acid compound found in the body that helps support normal nerve function and comfort. The PEA in Good Stretch is generally well tolerated when used as directed.

Our Vitamin B Complex is a patented form (PANMOL® B-COMPLEX) that contains higher vitamin B content (100x higher than in whole grains). It supports energy metabolism, nerve function, and muscle function - all areas that naturally need more support as dogs get older.

More comfortable in 90 days,
or your money back.
