Ruff Greens and Dinovite are two of the most popular powdered nutritional supplements for dogs, but they take different approaches to canine nutrition. Ruff Greens is a comprehensive all-in-one formula with 20+ vitamins, 15 probiotic strains, 20+ digestive enzymes, and Omega oils — all vegan and human-grade. Dinovite focuses primarily on skin and allergy support through probiotics, prebiotics, and Omega fatty acids. This guide compares them head-to-head on ingredients, price, and results.

Ruff Greens VitaSmart is a comprehensive nutritional supplement powder developed by Dr. Dennis Black, a Naturopathic Doctor. It is designed to address the nutritional gaps left by commercial kibble by providing a full spectrum of live nutrients in every scoop.
The formula is built around four pillars of canine nutrition. First, it delivers over 20 essential vitamins and minerals that are often destroyed during the high-heat processing of kibble. Second, it includes 15 strains of probiotics to support gut health and immune function. Third, it contains more than 20 digestive enzymes to help dogs break down and absorb nutrients more efficiently. Finally, it provides a balanced blend of Omega 3, 6, and 9 fatty acids for skin, coat, joint, and brain health.
Ruff Greens is manufactured in an FDA-registered, GMP-certified facility in the United States, and the formula is 100% vegan and made with human-grade ingredients. It is designed for all breeds and all life stages, from puppies to senior dogs [1].
Dinovite is a powdered supplement that has been on the market for over 20 years. It was created by a professional dog breeder and trainer, and it positions itself primarily as a solution for dogs with skin allergies, hot spots, yeast infections, and digestive issues.
The Dinovite formula centers on probiotics and prebiotics for gut health, combined with key ingredients like Zinc Methionine Complex, Vitamin E, dried kelp, ground flax seed, and yeast culture. These ingredients are chosen to target skin and coat health specifically, with Omega fatty acids sourced primarily from flax seed [2].
Dinovite has helped over 1,000,000 pets and offers a 90-day money-back guarantee on first purchases. It comes in four size-specific formulations for small, medium, large, and giant breed dogs.
The most significant difference between Ruff Greens and Dinovite is the breadth of the formula.
Ruff Greens takes a "complete nutrition" approach. The philosophy is that modern kibble is missing a wide range of nutrients due to high-heat processing, and a supplement should replace all of them. That's why the formula includes a full multivitamin and mineral complex, a diverse probiotic blend, a comprehensive enzyme profile, and Omega oils — essentially everything your dog's food is missing, in one scoop.
Dinovite takes a "targeted support" approach. The formula is built around the most common complaints pet parents have — itchy skin, allergies, hot spots, and digestive upset — and delivers specific ingredients to address those issues. It does this well, but it does not attempt to be a complete daily multivitamin.
| Ingredient Category | Ruff Greens | Dinovite |
|---|---|---|
| Multivitamin (A, B-complex, C, D, E, K) | Full spectrum (20+) | Vitamin E only |
| Minerals (Iron, Zinc, Selenium, etc.) | Full spectrum | Zinc Methionine Complex |
| Probiotics | 15 identified strains | Yes (count not specified) |
| Prebiotics | Yes | Yes |
| Digestive Enzymes | 20+ enzymes | Not a primary feature |
| Omega 3 | Yes (dedicated oil blend) | Yes (from flax seed) |
| Omega 6 | Yes | Yes (from flax seed) |
| Omega 9 | Yes | Not specified |
| Superfoods / Greens | Yes (superfood blend) | Alfalfa, Kelp |
| Yeast-Based Ingredients | No (100% vegan) | Yes (Dry Yeast, Yeast Culture) |
One notable distinction: Ruff Greens is 100% vegan and does not contain any yeast-based ingredients. Dinovite uses dry yeast and yeast culture as core components of its formula. For dogs with yeast sensitivities, this is an important consideration.
Price is where these two products diverge most dramatically.
| Product | Supply | Price | Cost Per Day (Medium Dog) |
|---|---|---|---|
| Ruff Greens VitaSmart | 28 days | $79.95 | ~$2.86/day |
| Dinovite for Dogs (Medium) | 90 days | $66.95 | ~$0.74/day |
Dinovite is significantly less expensive on a per-day basis. For budget-conscious pet parents, this is a meaningful advantage.
However, the price difference reflects the difference in formula scope. Ruff Greens includes a full multivitamin, a 15-strain probiotic, 20+ digestive enzymes, and a complete Omega oil blend — all manufactured in an FDA-registered facility with human-grade, vegan ingredients. If you were to purchase these components separately (a multivitamin, a probiotic, an enzyme supplement, and an Omega oil), the combined cost would likely exceed the price of Ruff Greens.
Dinovite delivers excellent value for targeted skin and allergy support, but it is not designed to replace a full-spectrum daily vitamin.
Ruff Greens also offers a free Jumpstart Trial Bag, allowing you to try the product before committing to a full purchase — a low-risk way to see if your dog responds well.
Choose Ruff Greens if:
Your dog needs comprehensive daily nutritional support. If you want a single product that covers vitamins, minerals, probiotics, enzymes, and Omega oils — essentially a complete nutritional upgrade for your dog's kibble — Ruff Greens is the more thorough option. It is also the better choice for dogs on a kibble-only diet where the nutritional gaps are likely to be broader, or for pet parents who prefer vegan, human-grade ingredients manufactured in an FDA-registered facility.
Choose Dinovite if:
Your dog's primary issues are skin-related — allergies, hot spots, itching, and yeast infections — and you are looking for a more affordable, targeted solution. Dinovite's 20+ year track record and 90-day money-back guarantee make it a low-risk option for pet parents focused specifically on skin and coat health.
Both Ruff Greens and Dinovite are legitimate supplements backed by real customer results. The right choice depends on what your dog needs.
If you are looking for a complete, all-in-one daily nutritional supplement that addresses the full spectrum of nutrients missing from processed kibble — vitamins, minerals, probiotics, enzymes, and Omega oils — Ruff Greens VitaSmart is the more comprehensive formula. It costs more per day, but it replaces the need for multiple separate supplements.
If your primary concern is skin allergies and digestive support on a tighter budget, Dinovite is a solid, proven option with a strong track record.
For pet parents who want to see the difference for themselves, Ruff Greens offers a free Jumpstart Trial Bag so you can try it risk-free.
1. Can I use Ruff Greens and Dinovite together? It is generally not recommended to stack two multi-ingredient supplements without consulting your veterinarian, as you may inadvertently over-supplement certain nutrients. Both products are designed to be standalone solutions, so choosing one that best fits your dog's needs is the better approach.
2. Is Ruff Greens or Dinovite better for puppies? Ruff Greens is formulated for all life stages, including puppies, and its comprehensive vitamin and mineral profile supports healthy growth and development. Dinovite also offers a puppy-specific formula. Either can work, but Ruff Greens' broader nutritional coverage may be more beneficial during the critical growth stage.
3. How long does it take to see results with either supplement? Most pet parents report noticeable changes within 2-4 weeks, particularly in digestion and energy levels. Skin and coat improvements typically take 4-8 weeks as new, healthier hair grows in. Dinovite specifically recommends allowing 90 days for full results, which is why they offer a 90-day money-back guarantee.
4. Are there any side effects? Some dogs may experience temporary digestive changes (softer stools or increased gas) when starting any new supplement. This is normal and usually resolves within a few days as the gut adjusts to the new probiotics and enzymes. Gradually introducing the supplement over 7-10 days can help minimize this.
