If you are searching for VetriScience Perio Support, you are probably deciding whether a daily dental powder could fit into your dog's routine, especially if brushing is a battle. Perio Support is one of the best-known dental powders sold in the US, and it takes an interesting approach built around zeolites and probiotics. This guide walks through what is on the label, what that formula is designed to do, where the evidence stops, and how it compares with a multi-ingredient brushless option like ours.
What is VetriScience Perio Support?
VetriScience Perio Support is a dental care powder for dogs and cats that you mix into food at mealtime. According to the product information sheet, it is intended for use between veterinary dental cleanings and is described as helping to maintain clean teeth and fresh breath. Retail listings also describe it as an everyday formula that supports gum health.
It is a supplement, not a medication. Like every powder on the market, it works around the edges of dental care. The foundation is still regular tooth cleaning and professional exams, a point the WSAVA Global Dental Guidelines (2020) make clearly.
VetriScience Perio Support ingredients
Here is the active ingredient panel as published on the product information sheet, per 2.5 g (about one teaspoon):
- Natural zeolites (500 mg): a mineral clay used in many supplements. It makes up the largest share of the formula.
- Proprietary probiotic blend (355 mg): six strains, including L. acidophilus, E. faecium, B. subtilis, L. casei, L. fermentum and L. plantarum.
- Cranberry powder (25 mg), yucca schidigera extract (7 mg), taurine (1.25 mg) and zinc as zinc ascorbate (0.8 mg).
The inactive list includes anise oil, calcium carbonate, Aspergillus fermentation extracts, fenugreek seed extract, silicon dioxide, vegetable fat and yeast fermentation solubles. Retail pages sometimes show a shorter or incomplete list, so always check the label on the jar you are actually buying.
How VetriScience Perio Support is supposed to work
The design logic is two-pronged. The zeolites are positioned as the part that interacts with plaque, while the live probiotic strains are positioned as a way to influence the bacteria that contribute to bad breath. Cranberry, yucca and zinc are included as supporting ingredients.
This is a reasonable idea, and it helps to know what is and is not established. Live probiotics for oral health are an active area of research, and results in dogs are still limited. The product page we reviewed does not cite a clinical study, and one retail listing uses the phrase "clinically tested" in the title without linking the data. That does not mean the product does not work for some dogs. It means you should treat the claims as a label-level description rather than as proof, and look for independent data before relying on them.
How to use VetriScience Perio Support
The information sheet gives weight-based amounts per meal: roughly 1/4 teaspoon up to 15 lb, 1/2 teaspoon for 16 to 30 lb, 3/4 teaspoon for 31 to 60 lb, 1 teaspoon for 61 to 90 lb, 1.5 teaspoons for 91 to 120 lb and 2 teaspoons over 120 lb. Mix it into food, and give it with or after a meal to reduce the chance of stomach upset. The sheet also notes that safety in pregnant or breeding animals has not been established. Directions can differ between listings and package sizes, so follow the label on your jar and ask your vet if you are unsure.
Pros and honest limits
What people tend to like: it is a powder you add to food, there is no brushing, and the strain list is easy to read. It is also made for both dogs and cats, which suits multi-pet homes. Cat owners who also need parasite control can compare options in cat flea and tick chewables and oral treatments.
The honest limits:
- The formula leans on one main mineral and a probiotic blend. It does not include an enzyme system, a prebiotic fiber, or a seaweed component.
- Probiotic counts and strains are listed as a proprietary blend, so you cannot see the amount of each strain.
- No powder replaces professional cleanings. Periodontal disease is common, as Wallis and Holcombe (J Small Anim Pract, 2020) reported, and bad breath that does not clear up deserves a vet exam.
- Brushing frequency matters. Harvey and colleagues (J Vet Dent, 2015) found that how often teeth are cleaned affected plaque, calculus and gingivitis, and a Swedish survey (Svärd and Enlund, 2023) found that only about 42% of owners brushed daily even after a periodontitis diagnosis. That gap is exactly why dogs who refuse the brush need a realistic option.
VetriScience Perio Support vs a multi-ingredient dental powder
Many dental powders rely on one or two headline ingredients. Our Pure Majesty Pets Dog Dental Powder was built as a layered formula, with each ingredient doing a different supporting job:
- Hydroxyapatite (15%), the mineral found in tooth enamel.
- Kelp, Ascophyllum nodosum (8%), a seaweed that was studied in dogs in a double-blind, randomized trial (Gawor et al., 2018) using edible treats.
- GOX/LPO enzymes (0.6%), the enzyme idea used in enzymatic toothpastes.
- Inulin (14%) and oral probiotic lysate (0.3%), a prebiotic and a postbiotic that does not rely on live organisms surviving in the bag.
- Zinc citrate (0.6%) and green tea (0.5%), both familiar in oral-care products.
- Pork liver (10%), so dogs actually eat it.

Neither product removes existing tartar, and neither replaces a vet dental exam. If you want to compare other well-known powders, see our reviews of Plaque Off, PetLab Co dental powder and Iron Paws, or our guide to the best dog dental powder.
How to choose a dental powder for your dog
Whatever brand you pick, look for a full ingredient list with amounts, a clear statement of what the product is for, honest wording that avoids cure or removal claims, and a realistic plan that still includes vet exams. Introduce any new supplement slowly. For a deeper look at the seaweed ingredient, read kelp dental powder for dogs, and for the brushing question, see dog toothpaste vs dental powder.

VetriScience Perio Support: FAQ
Is VetriScience Perio Support the same as Perio Support Pro?
No. They are separate products with different formulas, so check which one is on the label before comparing. This article covers the Perio Support powder.
Can VetriScience Perio Support remove tartar?
Tartar is hardened and generally needs professional removal by a vet. Powders are positioned as ongoing support between cleanings, not as a way to remove existing tartar.
How long does it take to see a difference in breath?
It varies by dog and by what is causing the odor. If breath stays bad after a few weeks, or you notice red gums, drooling or a loose tooth, book a vet exam rather than waiting.
Can I give a dental powder to a dog who already eats probiotics?
Often yes, but tell your vet about everything your dog takes, especially if your dog has a sensitive stomach or a medical condition.
Does a dental powder replace brushing?
No. Brushing remains the gold standard. A powder can be a practical add-on or an alternative for dogs who will not tolerate a brush.
The bottom line
VetriScience Perio Support is a widely available zeolite-and-probiotic powder, and for some households it is a convenient way to add oral-hygiene support at mealtime.
