Top 10 Best Supplements for Senior Dogs: Expert-Tested & Vet-Approved

Customer Review: “These are the most disgusting vitamins I have ever purchased for my dog. The minute you opened them it smells like medicine my dog smells it and won’t take it for anything. It’s awful smell awful.. I don’t know what they put in that damn thing. It definitely doesn’t seem appetizing at all not for me as a human.”

Customer Review: “I’m sure it’s a good product, but my picky dog refuses to eat them. Since I can smell the medicine scent coming from them I know she does. She doesn’t put anything in her mouth without a good sniff first lol.”

Customer Review: “My Shi Tzu Bobo is 12 yrs old. His back legs are getting weak.and seems to struggle to get up. He has been very grouchy for years. Thought it was just his attitude, but everything changed after wearing this collar for a couple of weeks. .I tried giving him glucosamine treats, mixing them with his food trying to disguise in any way possible and…guess what ..the only thing left in his bowl was the treat. If he got one in his mouth he would spit it out ! Impossible ! This collar is excellent! It’s worth the money because he gets around better and seems he’s even a little frisky! And no more fighting with those glucosamine treats …His grouchy attitude is gone…I can even groom him without dodging some sharp little teeth !! 1st time ever ! Well worth the price. It doesn’t bother his skin and has a pleasant smell. I’m ordering another one so I can keep my sweet baby happy !!”

Customer Review: “My mixed pomeranian/shi-tzu is 12 years old. He is suffering from hind leg arthritis. He loved going on long walks but could no longer walk a full city block.After a lot of research and paying for meds that I didn’t like my dog to take, I found this collar on Chewy. When received it, I opened the package and the smell of the herbs hit me. It’s a nice cozy smell. I put it on my 🐶 and within minutes he started jumping around in excitement!Took him outside and he walked 2 full blocks without wanting to go into his stroller. The collar put the pep back in his step!!!It does last 30 days. Maybe more but when the 30-day mark was approaching I ordered another one from Amazon.I have subscribed to this item! Do not hesitate, if your fur baby is in pain this is better than all the expensive meds the Vet will make you purchase.”

Customer Review: “I’ve been using this multivitamin for my 10-year-old rescue mix and noticed his coat became shinier and he had more energy within two weeks. He’s never been a fan of pills but these soft chews he actually looks forward to!”

Customer Review: “Great option if you’re avoiding synthetic additives. My dog has sensitive digestion and this doesn’t upset his stomach like other brands sometimes do.”

Customer Review: “I bought these Vitamin K supplements because our dogs were accidentally poisoned when the vacant house next door was being rehabbed. They had a mice/rat and other vermin problems. My dogs picked up a dead animal in our fenced yard that was probably brought in by a cat or racoon. Both of my dogs became very ill. My Frenchy recovered within a week or so, but my Maltese was just too sick. I took him to the vet, who gave him an antibiotic, but little Basil lost all of his hair, 1/2 of his body weight, and all of his vigor. His skin was bright red and the black spots on his skin (typical of Maltese), disappeared. We thought we were going to lose both dogs and prepared ourselves for the loss. Fortunately, Basil was a fighter and he held on for another two weeks, but with little improvement. Since the vet concurred that he had probably been poisoned, I took matters into my own hands.I bought these Vitamin K tablets and started Basil on a double dose. Within just a couple of days his skin started to lighten up. He started eating again too. He has been on these supplements for about 14 days. His black spots have returned and his skin is a mostly light pink and still fading. He has gained back about 2/3 of the weight he lost, and his hair has just started growing back. I think he is out of the woods thanks to these vitamin K tablets!”

Customer Review: “I grind these up to a powder and sprinkle on my dog’s food for his morning meal. He hasn’t turned his nose up to the taste, but I also add a bit of powdered probiotics to his kibble, and I know he likes that. He is 11 years old and his energy seems to have increased a bit but I can’t be sure its the Vitamin K or the probiotics. Will continue to use this.”

Customer Review: “My golden retriever mix is 11 and has always been active. Recently he started limping after walks. After two weeks on this, his gait is almost normal again. Worth every penny!”

Customer Review: “Smells strongly of fish and beef, but my dog doesn’t mind it. He takes it willingly and seems more comfortable moving around.”

Customer Review: “We’ve used Nutramax Cosequin for years with our aging dogs, and it continues to deliver excellent results. Our senior yellow lab has shown a clear improvement in agility and overall comfort since starting it — getting up is easier, walks are smoother, and he just moves with more confidence.This supplement has been consistently reliable across multiple dogs we’ve owned. It’s gentle on their stomachs, easy to give, and provides steady, long-term support for aging joints. For any dog starting to slow down or show stiffness, this is absolutely worth trying.Highly recommended for maintaining mobility and quality of life in senior dogs.”

Customer Review: “I truly cannot believe how much this supplement helps my mid age dog keep up with his buddies at the play care center. He comes home a bit tired, but no longer suffers from the obvious aches and pains he used to. He loves the taste of the Cosequin tablet, and happily gobbles it up every day. He’ll even remind us should we forget to give it to him at the usual time. The product has no unpleasant smell like others we’ve tried in the past. Nor do we have to hide it in peanut butter or cheese to get him to take it. Our dog is acting like a puppy again and has much more energy, and seems to be happier. We are very glad we purchased this supplement. This supplement is a little pricey, but as far as we are concerned the benefits are worth every penny.”

Customer Review: “The media could not be loaded. I love NOW brand supplements for me, so I tried these for my 11 year old dog. He’s generally very healthy and active, but we noticed he was starting to slow down a little: laying around more, not as active as usual on his walks, shaking in the hips when he squatted, etc. After a month of taking this supplement daily, he’s back to his old bouncy self! I‘m really impressed by how much he’s visibly improved in such a short time. Also, he actually likes taking the pills! I toss it to him like it’s a treat and he gobbles it down no problem!”

Customer Review: “We started our 5 1/2 year old English Bulldog on these supplements when she started having a difficult time going up/down the stairs. We really have noticed a difference in her. She doesn’t seem to ‘labor’ up the stairs anymore. Keep in mind that she doesn’t have a weight issue – she’s a SOLID girl, don’t get me wrong, but it did help her since we didn’t want to start medication at her age. It’s worth a shot!!”

Customer Review: “These really help my little shorkie with her patella plexia. She seems to be doing great with mobility, and has improved from a limp on walks to none. She does not like the taste, but they chew well and the benefits are worth it.”

Customer Review: “Great treat to throw in my dog’s food. My pup has had joint pains since 5 years old after twisting his paw. This small treat is easy for him to eat and shows it keeps him active.”

Customer Review: “These are perfectly meatball-textured and dog-smelly enough for our dog to absolutely go nuts for them. They’re about the size of a large cheese puff or half a Tostino’s pizza roll, and they crumble easily if you want to turn them into a topping for your dog’s kibble (we do that often). The bag is a decent size for what you pay and unless you’re a VERY generous mommy or daddy (or you have more than two fur babies), it should last you a month, or pretty darn near close to it. They seem pretty fresh when we open the bag. I mean, of course, they stink, but they don’t STANK, if you know what I mean. Plus they’re still relatively soft; not mushy soft like wet dog food, but they aren’t like bully sticks, either. 🤷🏻\u200d♀️.We buy them regularly, and Poochie* devours them every chance he gets. He comes running whenever he hears the bag open (and he must smell them, because he’s picky about which bags he RUNS for and which bags he mosies for. Have you ever seen a Chiweenie mosey? ROFL).Anyway, these are a big hit in our house. He’s not big on chewies (ever since his girlfriend died right when Co-id hit, he hasn’t really played much or chewed on things). He’s old-ish, though, so the vet said it could be that or he just doesn’t like the feel of chewing anymore, so we have to get sister treats. These are perfect.Sometimes I break them up into 3 or 4 pieces (remember, he’s small) and toss them around the house for him to find… Stimulate his mind and his hunting instinct. He loves that, too. You should use treats as a game for your pups. For training, or for other games. Make them earn them. They feel better when they work for their food. It’s instinct.I WOULD recommend these.*Names have been changed to protect those who cause havoc but can’t protect themselves, so we have to do SOMETHING to protect them. 🤷🏻\u200d♀️💙 ENJOY!”

Customer Review: “My dog loves these. She is picky about treats that are good for her joints but can’t get enough of these. They are soft enough for her so we can break them up for her. She’s a chug(chihuahua/pug mix). They would be good whole for a large dog or broken up for smaller dogs.”

Customer Review: “My 12-year-old shepherd mix had terrible gas and couldn’t climb stairs comfortably. Within ten days on this bundle, his bathroom habits normalized AND he’s bounding up the porch again. Miracle workers!”

Customer Review: “Took forever to get my picky eater to accept anything, but these chews won him over immediately. Now he waits by the cupboard every evening like clockwork.”
