The Best Dog Supplements

Updated April 2026·Experts: Healthline · Community: DogAdvice, Rottweiler, TechnoBarkDogGear

Best Overall Joint Supplement

Glucosamine + Chondroitin + MSM Joint Supplement (e.g., Cosequin DS or Nutramax)

$25-$60

Start this one early, multiple Reddit owners credit starting joint supplements at age 7 with their dogs still acting like puppies at 12. Don't wait for arthritis to show up.

What holds up

  • Glucosamine + chondroitin combo is the most evidence-backed supplement for canine joint health, recommended by vets
  • MSM adds anti-inflammatory support that reduces pain and swelling
  • Vets recommend starting in large breeds as young as 7 before arthritis symptoms appear
  • Available at Costco (Cosequin) making it cost-effective for long-term use

What to know

  • Some vets note glucosamine alone may have limited evidence, the chondroitin component is considered more impactful
  • Takes weeks of consistent use before noticeable results
  • Dogs with shellfish allergies need to check sourcing, as many glucosamine products are shellfish-derived
Expert verdict
Vets may recommend joint supplements for dogs even before they show signs of arthritis, particularly large-breed dogs who may be at higher risk.

My dog is 14 (70lb retriever mix breed) these are our staples - as he's aged we add in other supplements depending on how he's doing, but he's been on joint supplements since he was about 7 and I 100% attribute how active he's still able to be now to starting them back when he was younger.

Yes I started the joint supplements early too and definitely held off a lot of the arthritis to the point of my vet even being impressed.

Best for Coat, Heart & Joints

Fish Oil / Omega-3 Supplement for Dogs (Salmon Oil)

$15-$40

If you only add one supplement to your dog's kibble, make it salmon oil. It's cheap (~$30 for 3 months), dogs love the taste, and the benefits are backed by actual research, not just marketing.

  • Inexpensive, roughly $30 for a 3-month supply; easy to add to kibble

What to know

  • Quality varies widely by brand, look for products with verified EPA/DHA content

  • High doses may interact with blood thinners, always confirm dosage with your vet
Expert verdict
Omega-3 fatty acids can be a natural way to reduce inflammation in senior dogs, helping with conditions such as canine arthritis. It can also help with decreasing pain, reducing the amount of inflammatory medication necessary, daily activities.

Salmon oil! It has helped my girl grow a gorgeous coat and is great for their joints! It's my biggest suggestion to anyone looking to up their dog's kibble. It's rather inexpensive at about $30 for a bottle that lasts like 3 months.

Best All-in-One Daily Supplement

Pet Honesty Hemp Hip + Joint Support (or similar multi-ingredient chew)

$25-$55

For dogs with poly-arthritis or severe joint issues, the combination of glucosamine and hemp in one chew is a game-changer. One Reddit owner said her dog went from unable to walk to 'unstoppable' on steroids plus this supplement.

What holds up

  • Combines glucosamine, MSM, and hemp extract for joint support and mild calming in one chew
  • Treat format makes daily dosing easy, dogs eat it willingly
  • Hemp extract may reduce inflammation without the psychoactive effects of THC
  • Reported effective even in dogs with diagnosed poly-arthritis alongside vet treatment

What to know

  • Hemp/CBD regulation is inconsistent, quality control varies significantly by brand
  • More expensive per dose than buying individual supplements separately
  • Not a replacement for vet-prescribed treatment in severe arthritis cases
From the community
I highly recommend pet honesty hemp hip plus joint support. Started giving that to my then 3 year old dog, now 6, because she was diagnosed with poly arthritis and she couldn't walk. With steroids and that she's unstoppable.

CBD rarely causes side effects (aside from increased appetite and thirst), but 'rarely' doesn't mean 'never,' so it's best to err on the side of caution and consult your vet. Most vets today are pretty well-versed in the benefits of CBD. In fact, on a recent visit, my vet recommended it to calm my dog's anxiety.

Best for Gut Health & Hydration

Goat's Milk / Bone Broth Supplement for Dogs

$10-$25

This is the most underrated dog supplement on the list. It costs almost nothing, dogs go crazy for it, and it solves the hydration problem that silently damages senior dog kidneys. Pour it over kibble and you're done.

What holds up

  • Goat's milk supports gut flora and digestive health with natural probiotics
  • Bone broth adds hydration to dry kibble, supporting kidney and urinary health in seniors
  • Highly palatable, even picky dogs will eat kibble soaked in broth
  • Inexpensive and widely available; can be rotated with other toppers for variety

What to know

  • Not a standalone supplement, works best as a kibble topper alongside other supplements
  • Goat's milk adds calories, which can be a concern for overweight dogs
  • Quality varies; avoid products with added salt, onion, or garlic which are toxic to dogs
Expert verdict
Adequate water intake is imperative for aging dogs, as total water content declines with age. This also helps the kidneys maintain typical function, which can help avoid dehydration and conserve electrolytes.

Are you feeding a kibble diet? If so; hydrating the kibble with water, bone broth, goats milk, or a rotation of these. Good for kidney and urinary health, and goats milk occasionally is good for gut flora.

Best for Anxiety & Stress Relief

Calming Supplement for Dogs (e.g., Dorwest Scullcap & Valerian or Zesty Paws Calming Bites)

$20-$50

These work best as a training aid, not a cure. But for reactive dogs, even a small reduction in baseline anxiety can be the difference between a dog that can focus and one that can't. Dorwest Scullcap & Valerian has a loyal following in the reactive dog community.

What holds up

  • Valerian root and scullcap are natural herbal calming agents with a long track record in reactive dog communities
  • Non-sedating, reduces anxiety without making dogs drowsy or unresponsive
  • Zesty Paws multivitamin chews are widely praised on Reddit for palatability and effectiveness
  • Good option for owners who want to avoid pharmaceutical anxiety medications in young dogs

What to know

  • Results vary significantly by dog, some owners see no effect
  • Smaller brands like Green Pantry have limited independent reviews to verify efficacy
  • Not a substitute for behavioral training and desensitization work in reactive dogs
From the community
We have tried a few calming supplements Yumove calming & nutripaw, he is currently on Dorwest Scullcap & Valerian tablets. We aren't looking for something that knocks him out just something that takes the edge off him to make life more enjoyable for him and to be able to catch his attention easier when facing obstacles.
