Finding the best dog vitamins on the internet can often feel like searching for the needle in the haystack — there are too many options, not enough research, and simply not enough time to try them all. Well, that’s where we come in: we’ve whittled down what felt like an endless array of supplements to a tidy top five, elaborating on the benefits of each, and generally doing the dirty work so you don’t have to. 

Like the dog food market, the dog vitamin market is growing steadily, and that means the options are only going to increase. But because dog supplements aren’t regulated by the FDA, there’s no guarantee that what’s out there is actually good for your dog. Thus, discerning which brand makes the best dog vitamins for your pooch is going to be difficult. Which is to say: it’s never been more important to conduct thorough research before a pet-related purchase (and, equally, it’s never been more important to consult your vet before making said purchase). 

How We Selected These Products 

Methodology 

This product guide has one very important North Star: Our love for our own pets (otherwise known, of course, as man’s best friend). Practically speaking, that means we’ve been as meticulous as possible in our research, and our selection is guided by a number of distinct questions. Namely, is the dog vitamin backed by research, or marketing hype? Is it affordable? Does it target any specific needs for the dog, and if so, what are they? Most importantly, is the dog vitamin something we would feed to our own pets? 

These questions get to the heart of the matter in categories of science, price, and efficacy. They’re how we’ve evaluated each product in order to produce reviews that are specific, thoughtful, and catered to you. Using our product guide as a map, you should be well equipped to navigate the dog vitamin landscape with both ease, and expertise. 

The Best Dog Vitamins: Reviews & Recommendations

Best Overall Dog Vitamins: Zesty Paws Multifunctional Supplements for Dogs

Why It Made The Cut: Zesty Paws’ all-in-one formula makes this multivitamin a winner across the board — whether your dog is struggling with gut issues, needs hip and joint support, could do with a shinier coat, or you’re simply looking for an overall boost to their diet. 

Specs:

  • Flavor: Chicken 
  • Size: 90 count
  • National Animal Supplement Council Approved: Yes

Pros: 

  • High-quality, grain-free ingredients 
  • Approved by the National Animal Supplement Council (NASC)
  • No artificial flavors, colors, or preservatives 

Cons:

  • More like a treat than a meal additive 

Zesty Paws has built an excellent reputation among pet owners for its reliable, flavorful, nutritious products. Thus, it should come as no surprise that we’ve included them here. This multivitamin in particular really checks all the boxes: it targets a variety of health issues, promotes healthy digestion and shinier coats, and isn’t tied to any specific breed, size, or age. 

That’s not to say, however, that Zesty Paws is perfect — and just because this multivitamin has worked for pet owners in the past doesn’t mean it will work for your pooch. Every dog is different, and closely observing your pet when trying out new supplements will go a long way in determining what’s best for your pet — regardless of reviews or word-of-mouth recommendations. Further, if your pet has a specific issue you’d like to address, you might be better off purchasing a supplement that’s more targeted. 

Best Dog Vitamins for Puppies: Nutri-Vet Multi-Vite Chewables for Puppies

Why It Made The Cut: Made by veterinarians, Nutri-Vet Multi-Vite Chewables are an easy way to ensure that your puppy is getting all the nutrients it needs.

Specs:

  • Flavor: Liver
  • Size: 60 count
  • National Animal Supplement Council Approved: Yes

Pros:

  • Formulated by veterinarians 
  • Approved by the National Animal Supplement Council (NASC)
  • Liver-flavored

Cons:

  • One pill per 10 pounds means a bottle won’t last very long for larger pups

Nutri-Vet Multi-Vite Chewables are typically a favorite among dogs for their liver flavor (in other words: these are super tasty treats). They also happen to be packed with vitamins, all of which help to boost metabolism, digestion, cardiovascular health, and skin health. 

But take note: if your pup is already consuming a healthy and well-rounded diet, and therefore isn’t deficient in vitamins, he probably doesn’t need these chewables. Intaking more vitamins than is necessary can actually harm a pup in some instances; for example, if he’s getting double the Vitamin A that he needs, that overconsumption could be toxic, could block the intake of other vitamins and minerals, and ultimately could lead to adverse reactions like stiffness of the joints. So, proceed with caution, keep a close watch over your pup, and always consult with your vet. 

Best Dog Vitamins for Seniors: Zesty Paws Multifunctional Supplements for Seniors

Why It Made The Cut: Zesty Paws Multifunctional Supplements specifically target problem areas for older dogs, making it our top choice for seniors. 

Specs:

  • Flavor: Chicken
  • Size: 90 count
  • National Animal Supplement Council Approved: Yes

Pros:

  • Suitable for all dogs, but catered to older dogs
  • Approved by the National Animal Supplement Council (NASC)
  • No artificial flavors, colors, or preservatives

Cons:

  • May leave a stain

It’s no secret that senior dogs need a little extra help with their health — whether it’s mobility, heart health, eye sight, gut health, or any other number of issues. They’re in their golden years and are often deficient in one area or another. Obviously, that’s where the vitamins come in — and, once again, Zesty Paws is top of its class. 

Zesty Paws Multifunctional Supplements for Seniors are actually perfectly fine for dogs of all ages, but this one specifically targets issues common in seniors, making this vitamin a great addition to the diet of your over-the-hill pooch. These vitamins specifically contain OptiMSM (which provides muscular support), Qmin+ (which may ease joint stiffness and support liver health), and Cran-Max (which improves urinary tract health). Packed with plenty of other vitamins too, this is a well-rounded support system in the form of a tasty, chewable treat. 

Best Dog Vitamins for Gut Health: Purina Fortiflora ProPlan Veterinary Supplements

Why It Made The Cut: Purina ProPlan Fortiflora is the best way to improve your dog’s digestion — plus improve the flavor of their food — making it our pick for gut health supplements.

Specs:

  • Flavor: Liver
  • Size: 30 sachets
  • National Animal Supplement Council Approved: No

Pros:

  • Contains guaranteed amounts of live active cultures 
  • Helps reduce flatulence 
  • Proprietary microencapsulation process for enhanced stability

Cons:

  • Not necessarily a long term solution for your pet

Purina Fortiflora ProPlan Veterinary Supplements could be perfect for your pet if they are experiencing trouble with digestion (think diarrhea, less-than-perfect poops, picky eating, etcetera). We can attest to the benefits: after purchasing it for one 15-pound, 2-year-old Jack Russell Terrier who kept waking us up in the night with bladder issues, this probiotic returned her digestion to normal within two days. Yes, it felt like a miracle, and yes, she now has perfect poops. 

That being said, this probably isn’t a long term solution for your pet, for a number of reasons. One, it’s fairly expensive (about $1 per meal, so you’re potentially looking at up to $60 per month). Two, it’s specifically formulated to help solve diarrhea and other issues — once they’ve been resolved, you should talk to your vet about how long you need to continue using this supplement. It could be that some other thing — food choice or allergies, for example — is the real cause of their gut issues, and getting to the root of the problem (versus simply attacking the symptoms) is key. 

Best Budget Dog Vitamins: ProSense Vitamin Solutions for Dogs

Why It Made The Cut: ProSense Dog Vitamin Solutions are the best bang for your buck, and serve as an everyday boost to your dog’s diet. 

Specs:

  • Flavor: With brewer’s yeast
  • Size: 90 count (comes in two bottles, so you get 180 total)
  • National Animal Supplement Council Approved: Yes

Pros:

  • Suitable for all ages
  • Packed with Vitamins A, D3, E, B1, B2, B3, B6, and B12. 
  • Great value 

Cons:

  • Not grain-free
  • Might require some peanut butter or another flavor mask

If you’re hesitant to spend a bunch of money on dog vitamins, or if your dog has no specific health issues, ProSense Vitamin Solutions could be the supplement for you. At $25 for 180 pills, the price per pill is much lower than other vitamin brands — thus, it’s a fairly low risk trial, and if your dog doesn’t like them, this seller offers free returns. They’re also appropriate for all ages and life stages, so you don’t need to worry about your dog’s age before purchasing. 

These pills are packed with nutrients, so you might want to run the ingredients list by your vet before feeding these to your dog. Like we’ve already mentioned, there is such a thing as “too much of a good thing,” and too much of a certain vitamin can be toxic. Otherwise, ProSense Vitamin Solutions are a great entry point into the ever-growing world of pet supplements. 

Things to Consider When Buying the Best Dog Vitamins

Research

It’s important to rely first and foremost on scientific research and your veterinarian’s advice when comparing dog vitamin brands. Consider whether or not the brand in question has conducted a thorough study of the effect of its supplements. Are their claims supported by scientific findings? Do they have quantitative data or simply testimonials? Either way, think critically about the risk involved before purchasing. There’s no guarantee that the brands with more research will automatically be better for your dog — but the more information you have, the better. 

Price

Dog vitamins are not a one-off purchase — you should be feeding them to your dog throughout their lifetime. Thus, it’s vital that the price point is realistic for your budget.

Efficacy 

Is your dog deficient in a specific area? Did your vet recommend improving something, like bone density or gut health, in particular? If you have specific touchpoints that you want to prioritize, use them to help you decide on your purchase.

Diet

Some dog vitamins cater to grain-free diets or other allergies – and some don’t. Read the fine print to ensure that your test run of a new vitamin is off to a good start. 

FAQs

Q: Are vitamins for dogs worth it?

Like most pet-related questions, it depends on the pet. That said, if your pet is eating a healthy and nutritious diet, you can probably assume they are already getting all of the nutrients they need. On the flip side, if they’re deficient in a specific area, are eating poorly, or not eating enough, a vitamin could be the perfect addition to supplement their diet — just ask your vet.

Q: Is fish oil good for dogs?

Fish oil is an excellent addition to a dog’s diet because it promotes a shiny coat, helps with itchy or dry skin, relieves allergies and promotes heart health — among other benefits. 

Q: How do I know if my dog is lacking nutrients?

Tell-tale signs of a nutrient-deficient dog include dry, itchy, or flaky skin, and a dull or otherwise unhealthy-looking coat. Of course, these symptoms could also be due to something like allergies or a thyroid issue, so it’s important to talk to your vet before diagnosing the issue yourself. 

Final Thoughts

Searching for the best dog vitamin brand is an important part of caring for your pet. After all, you are what you eat — and so is your pooch! That’s why we ultimately selected the Zesty Paws Multifunctional Supplements for Dogs as our overall best pick — it’s the vitamin with almost no boundaries (it’s all-sizes, all-ages, all-breeds), it’s the perfect starting point in your search for supplements. And who knows — it might just be the perfect choice for your furry friend.
