LOVE THIS PRODUCT.
Our 80 pound senior dog was having problems climbing stairs and jumping on the couch. We started using K9 Power products a few years ago and they havre helped him immensely. He plays and runs as if he's a puppy. We are very happy we found something that works Thank you K9 Power ❤️
GREAT PRODUCT!
We've been using K9 Power for over 2 years now and just transferred to the senior dog joint supplement. It's helped our old boy stay young and away from so much joint pain. Will continue to use this brand for all of our dogs!
5 STARS
I've had several foldies" over the last few years and could start to see their decline to my dismay. I tried "Young at Heart" a few years ago and was totally impressed with an oldie that was having mobility issues. I'm now giving this to my 16 year old who started to fail or appeared to start to fail, several months ago with rear weakness and just not as perky as before in attitude. I put him on this and he moves like a two year old, regained strength and vigor all the way around! All of the products perform as described!! I'm especially impressed with the "Young at Heart! I believe it has given several of my oldies substantial support that contributed to their mobility and alertness. I also use the "Show Stopper" and can see a visible difference in coat and glow as well as the "Digest Forte gives me assurance that they are getting the most benefft from their meals.
OLD DOG ENERGY ENHANCER
I have been feeding this to my old dog for at least 3 years and have added it to my other dogs as they aged noticed an improvement almost immediately in their activity level and their brightness. Love this additive
BEEN USING FOR YEARS
We have been giving this product to all of our dogs for over 10 years now. Is that possible? It really seems to keep them young and they love the taste. We pair it with Joint Strong
MUST HAVE... FOR ANY DOG OWNER!
I've used Young At Heart with several generations of my Dals. I compete in Obedience, Agility, Rally, Dock Diving, Tracking Conformation, etc. Young At Heart helps them have a long and healthy career and life in general ❤️❤️❤️
5 STARS
I have given this product to 4 older dogs and have recommended it for others... all with great results. I have two 8 year old dogs that both still run agility on this product and one 11 year old Malamute that I swear still runs around like a 2 year old. Great product. The product arrived earlier than expected. I love this product and this company and will buy from them again and again.
OUR 11 1/2 YR OLD GOLDEN LAB'S EYES CLEARED
Kodachrome has been on JointStrong all his life; now he's on YAH plus joint supplement. His joints have always been fantastic, thanks to JointStrong (he even recovered quickly after falling in a hole at age 11)..but his coat was a getting a bit dull, his face drooped a little, and his eyes were clouded. We're finishing the first 3 mo on YAH and his eyes are clear and bright, his face looks uplifted, and his coat is brilliant! People are always confused when they first see him run--they assume he's 2 or 3 and then they see white in his muzzle and are stunned to find he's outrunning their 7-y-o dog. We appreciate K9 Power and hope Koda is with us and feeling good for many more years!

12 Benefits in 1 Scoop of K9Power Young at Heart™
Questions & Answers
We recommend Young at Heart for dogs in the range of 6 to 7 years of age. As the dog ages, its organ systems become less efficient in metabolizing nutrients and there often is need for functional ingredients that will maintain or enhance the health and well-being of the dog. If prior to this, you feel your pet is showing signs of aging you can certainly begin to introduce Young at Heart.
Young at Heart will benefit any breed of dog that is approching it's senior years.
Our Young at Heart formula is designed for dogs over 6 months of age. Our recommendation would be our Puppy Gold® formula. Puppy Gold is formulated similarly to canine mothers’ milk to support your puppy’s development after weaning. Puppy Gold includes powerful ingredients that include the primary building blocks of muscle, bone, tendon, ligaments, articular cartilage and other connective tissues. Pups should remain on Puppy Gold until 12 months of age and transition to our other formulas.
It is certainly okay for you to give your dog more than one of our supplements. If you are using two supplements, we recommend splitting them between AM and PM meals. Anytime you start a new supplement, we recommend you introduce it slowly with ½ of the recommended amount and gradually work up to the full amount over 7-10 days. Once your dog acclimates to the first supplement, you can introduce the second one on the same starting schedule.
Our recommendation would be our Puppy Gold® formula. Puppy Gold® is not only formulated for puppies but the canine mother, too, benefits from ingestion of Puppy Gold throughout the course of gestation and lactation.
This is extremely rare! All our formulas are made with real meat that dogs absolutely go crazy for. We have taste tested our formulas on dogs from extra-large to toy breeds with a big paw up from all. We are all dog owners at K9 Power, and we know some dogs just have different preferences which is why we offer a 100% money back guarantee.
Our products are made with the highest quality ingredients, and we do not use flax, wheat, corn, soy, by-products, artificial colors, or artificial flavors. If your dog has known allergies, please review our ingredient list on the products label. We encourage you to touch base with your veterinarian with questions on your dog’s diet.
All our formulas are stamped on the bottom of each container and includes the Lot# and Expiration (Best By) Date. Term of Validity is 24 months starting from product's production date. Store shelf-stable supplement products in a cool, clean, and dry place. Never store above stove, under sink, in a damp garage or basement, or any place exposed to high or low-temperature extremes.
Always store your supplement in a cool dry area, tighten the lid and keep the container out of reach of your dog (dogs love the taste!). If your dog consumes more than the recommended daily amount, watch your dog and contact your veterinarian with concerns or guidance.
All our products are manufactured in the U.S.A. in an FDA registered, cGMP (Good Manufacturing Processes) certified facility. Our facility additionally is APHIS and USDA organic certified.

- KBKristi B.Verified BuyerRated 5 out of 5 stars2 months agoStill Sniffin’, Still Sprintin’, Still Sassy
My retired K9 Luna (9.5) and her bestest bud, Bear, (a whole month older) have been on Young at Heart for about six months—and let me tell you, the name fits. They may be a tad slower than their prime “zoomie” days, but they’re still out there chasing frisbees like it’s the World Cup of backyard athletics.
Luna lives for demo days. The second she sees the gear come out, she’s locked in—nose on, tail wagging, and ready to show the rookies how it’s done. She still crushes her odor finds like a pro, and I swear she struts a little harder afterward.
Keeping these two legends healthy is non-negotiable. Young at Heart has helped them stay active, sharp, and just the right amount of mischievous. If you’ve got a retired working dog who refuses to “retire,” this stuff’s worth a look.
Age is just a number when you’ve still got frisbees to catch and odors to crush.
KPK9 Power2 months agoHey Kristi! Amazing review and pics/video! Thank you! Great-looking pack; they look super happy and healthy!
- DSDeb S.Verified BuyerRated 5 out of 5 stars3 months agoVery Impressed
I have an 8 yr old Border Terrier that was always chewing at his feet. We work with his vet , food changes you name it with minimal success.
After putting him on Young at Heart the whatever was bugging him is gone after 2 bags
A huge thank you for developing this product.
Stanley Sugar Bean is so much happier now
KPK9 Power3 months agoThanks Deb for the kind words, we are so happy Mr Stanley Sugar Bean is doing so much better!! Don't know what is cuter, the pics of him or his name!! Best wishes from the K9Power team!!
- BCBrittany C.Verified BuyerRated 5 out of 5 stars7 months agoShe likes it
My lady Dane is aging and we wanted something to supplement with her food that she doesn’t want to spit out. She thinks she’s getting special snacks on her dinner now.
KPK9 Power7 months agoHey Brittany, thanks for the nice review. We are so happy that your pretty girl loves the taste and is nutritionally benefiting as she ages :)
- NJNikki J.Verified BuyerRated 5 out of 5 stars8 months agoGreat Product!
My dog is a 7 y/o Jack Russell. She has been through a lot in her younger years, but is still overall healthy. I noticed she seemed less active and I had been using other supplements because of “convenience” (chewables, rather than powders) but what a waste of money they were. Young at Heart made a huge difference. She’s like a puppy again!
KPK9 Power8 months agoHey Nikki, you're right about powders vs. chews! K9Power has been producing powdered supplements for over 25 years, and we are honored to know how many tens of thousands of dogs we have helped live healthy, happy lives, just like your cute little beach girl here!! Best wishes to you both!
- RARich and A.Verified BuyerRated 5 out of 5 stars10 months agoOur Labs!!
We raised AKC Labs for over 20 years here in Cabot, Vermont. We discovered K9 products with the puppy formula when we were looking for a supplement for our moms during pregnancy. Then we continued using it during the next 2 months for the mom and puppies. We liked the product. Then our oldest retired Lab, Bella, was turning 11 and we started noticing her limping. We bought YAH and started using it for her, and her BFF Toby. He was also 11, retired. They both reacted very well! We were again so amazed. Toby lived to be 13 1/2, we lost h last summer. However, he got around well. Bella is now 14 and she hangs with our other 3, trots outside, and even climbs 2 steps in and out of the house several times a day. We ran out of YAH several months ago, and the place we ordered it from was Out of Stock. We came to the K9 website, ordered as a new customer with a discount code, but you would not ship to Vermont! So I had it shipped to my brother in NC, and he then shipped it me. With 4 dogs, we go through a lot. It is time to reorder, I hope the shipping has changed, and I too hope for a bigger container to buy! Thank you fir a product that DOES really work and has healthy ingrediants that we believe in!
KPK9 Power9 months agoHi Rich & A! thank you for the great review and photo. Young @ Heart is a wonderful product and we love to hear how much this helped your senior dogs with their wellness and longevity. We are sorry to hear of the loss of your Toby :( but he clearly lived a wonderful, healthy life. We are thrilled to tell you we now do ship directly to VT! If we can be of any further assistance, or if you have any questions, be sure to reach out to us at support@k9power.com and again, thank you for all your support!!
- JSJennifer S.Verified BuyerRated 5 out of 5 stars12 months agoVibrant!
I could and eventually will write 4 reviews on the 4 different products I am using daily but this result is my most treasured. My now 11.5 yr old Staffordshire Bull Terrier has dealt with Valley Fever for the last 7 yrs and I have had him on an arsenal of products. Found he had spondylosis incidentally on x-ray. His gait was only slightly off at that time but has worsened over the last year. I have a chiropractor come in every couple of months and he goes to another vet for Physical therapy. I ordered this product for him at the same time as starting Digest Forte for my French Bulldog. Vibrance is all I can say. He is already that way but this really lit him up in a noticeable way to both practitioners mentioned above. He always dances but now with that little bit extra that says Mom, this is good stuff!! I love it and am so thankful to be using it. I added Show Stopper into his daughter's diet as she is sailing towards her Bronze Grand Championship (she is a chip off the old block!), the Digest Forte is another success and now have a puppy French Bulldog that I am trying Puppy Gold out on so depending how she comes along, will undoubtedly use it on a future planned litter of Staffords. Thank you K9 power, 4 containers on the counter get used every morning!! Oh I guess 6 products because I keep Hydration and Super Fuel on hand for performance events and times of trouble. Lots of reviews could be written! K9 Power for the Win!! Photo of him out as an 11 yr old Veteran…
KPK9 Power12 months agoWOW Jennifer, what an awesome review of our products and the great success you have seen. This is why our team here at K9 Power LOVES to do what we do! It's all about the dogs health and wellness, and the road to a wonderful happy life. THANK YOU and we wish you and your pack great health and happiness!

- LHLee H.Verified BuyerRated 5 out of 5 stars1 year ago2nd Generation loves Young at Heart
I used YAH for my heart dog, Csabre.....who lived to be over 14 - longer than anyone in her litter. Her son, Komet, was 12 on Halloween....I kept him and his littermate Kira. The rest of the litter has passed. I put Komet on YAH over a year ago, he was starting to slow down. His mobility improved pretty quickly - he easily can jump on my bed and still jumps into the back of my Expedition. He is sound and active overall. I have my 9 year old, Lucca, on it now as well.
