What to Expect in 12 Weeks?

Boost in energy & mood

Noticeable fresher breath

Improved gut health

Features 9 active ingredients

90% of dogs suffer from periodontal disease by age 2

Plentum is scientifically shown to target the root of poor oral health.

WHY THIS MATTERS?

In a 7-day, double-blind, placebo-controlled trial involving 10 dogs , those given the Canine Oral Health Postbiotic (COHP) showed a significant improvement in canine oral health. After just seven days, dogs given COHP had a 44% reduction in the microbes that produce volatile sulfur compounds (VSCs), the source of bad breath (p=0.08). Metagenomic analysis confirmed a reduction (p<0.01) in harmful bacteria, including a decrease in 7 potentially pathogenic taxa out of the 9 total taxa.

90% of dogs suffer from periodontal disease by age 2

Plentum is scientifically shown to target the root of poor oral health.

WHY THIS MATTERS?

In a 14-day clinical trial with 24 dogs, COHP was proven to significantly combat bad breath by lowering Volatile Sulfur Compounds (VSCs) 27% more than a placebo (p=0.004). This objective measurement was supported by human perception, as twice as many dogs on COHP showed improved malodor scores after 7 days. Furthermore, COHP promoted a healthier oral microbiome by reducing key pathogens like Porphyromonas cangingivalis, the most prevalent pathogen in early periodontal disease.

90% of dogs suffer from periodontal disease by age 2

Plentum is scientifically shown to target the root of poor oral health.

WHY THIS MATTERS?

In vitro studies have proven that it attacks the root causes of bad breath and poor oral health. The ingredient demonstrated a statistically significant ability to reduce the volatile sulfur compounds (VSCs) that cause bad breath by an average of 85%. Furthermore, it showed a near-complete disruption of plaque-forming oral biofilms by an average of 98%. In direct comparisons, COHP's ability to disrupt biofilms substantially outperformed other common oral health ingredients like zinc, spirulina, and brown algae

ADDITIONAL INFO

✕

Our Canine Oral Health Postbiotic (COHP) is validated by a robust, double-blind, placebo-controlled study using a "dirty tooth model," proving its effectiveness even without brushing. The trial employed highly accurate measurements, including objective Halimeter readings for VSC levels and advanced 16S rRNA metagenomic sequencing to analyze microbiome changes. Beyond its clinical efficacy, COHP is highly palatable for dogs and exceptionally stable, ensuring its potency through manufacturing and shelf-life in both wet and dry conditions.

How It Works

Every Ingredient Matters

One simple sachet, a dozen ways to support your dog! Plentum delivers targeted nutrition for 12 vital functions including digestion, fresh breath, and a strong immune system, all in one.

Fish Oil (Omega 3)

Fish Oil (Omega 3)

Skin, joint & cognitive health.

Fish oil is a rich source of Omega-3 fatty acids, specifically Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA). These essential fatty acids play a crucial role in reducing inflammation throughout the body, supporting cellular function, and promoting the health of various organ systems.

- Supports joint health.

- Supports cardiovascular health.

- Supports cognitive function.

Clinical studies

Canine Oral Health Postbiotic

Canine Oral Health Postbiotic

Healthy oral microbiome & fresh breath.

This patent-pending postbiotic is specifically designed to target unwanted microbes responsible for poor oral health in dogs. It has been scientifically proven to significantly reduce volatile sulfur compounds (VSCs), and disrupts oral biofilms by an average of 98% which causes bad breath.

- Promotes a healthy oral microbiome.

- Reduces bad breath compounds (VSC and biofilms).

Clinical studies

Colostrum

Colostrum

Immune function & gut health.

Colostrum, often referred to as nature's first milk, is rich in antibodies, growth factors, and other bioactive compounds. These components help to significantly boost the immune system, particularly in developing puppies or dogs needing extra immune support. It also plays a vital role in supporting gut integrity by fortifying the gut lining, which can reduce gastrointestinal issues and improve nutrient absorption

- Supports immune system function.

- Supports gut health.

- Supports skin health.

Clinical studies

Inulin

Inulin

Prebiotic; digestive health.

Inulin is a type of prebiotic fiber that serves as nourishment for beneficial gut bacteria. By promoting the growth of these good bacteria, inulin supports a healthy and balanced gut microbiome, which is essential for overall digestive health. It also helps with regular bowel movements and reduce instances of constipation, contributing to improved digestion

- Helps to maintain gut integrity.

- Supports digestive health.

- Supports normal bowel function.

Clinical studies

L-Glutamine

L-Glutamine

Gut lining & immune function.

L-Glutamine is an amino acid critical for maintaining the integrity of the gut lining. It acts as a primary source for intestinal cells, helping to repair and strengthen the gut barrier and reduce the risk of "leaky gut" syndrome. Beyond gut health, L-Glutamine is important for muscle recovery after exercise and supports the immune system, especially during periods of stress.

- Supports gut health.

- Supports muscle recovery.

Licorice Root Powder

Licorice Root Powder

Normal inflammatory response & digestion.

Licorice Root Powder contains compounds that exhibit anti-inflammatory properties, which can be beneficial for dogs experiencing inflammation related to arthritis or skin issues. It also acts as a digestive support by soothing the digestive tract lining, potentially helping with conditions like gastrointestinal discomforts.

- Supports normal inflammatory response.

- Supports digestive health.

- Supports immune system function.

Zinc Methionine

Zinc Methionine

Healthy skin & immunity.

Zinc is an essential trace mineral that, when complexed with methionine, is easily absrobed by body. It is crucial for maintaining healthy skin and a shiny coat, with deficiencies leading to skin lesions. Additionally, it is important for reproductive health and proper growth and development in puppies.

- Supports skin health.

- Supports immune system function.

- Supports reproductive health.

Selenomethionine

Selenomethionine

Antioxidant function & thyroid health.

Selenomethionine is an organic form of selenium, a powerful antioxidant that helps protect cells from oxidative damage caused by free radicals. This antioxidant support contributes to overall cellular health and can reduce the risk of various health issues. It is also important for maintaining healthy thyroid function, which regulates metabolism and energy levels.

- Supports antioxidant function.

- Supports thyroid function.

- Supports immune system.

Vitamin E

Vitamin E

Antioxidant function & skin health.

Vitamin E is a fat-soluble vitamin primarily recognized for its potent antioxidant properties. It protects cell membranes from oxidative stress, thereby supporting overall cellular integrity and health. In terms of skin and coat health, Vitamin E promotes a healthy skin barrier and a shiny, well-nourished coat.

- Supports antioxidant function.

- Supports skin and health.

- Supports immune system function.

Frequently Asked Questions

Advanced K9 Microbiome Care is more than just a supplement—it’s a simple, science-backed way to support your pup’s long-term health. Each sachet delivers advanced dental care for fresher breath, plus a postbiotic formula to support digestion, joints, and overall wellness—all for just $1 a day. 

Designed for daily use, it helps keep your pup happy, comfortable, and full of energy at every stage of life. Plentum’s products are developed for long-term benefits, so you can enjoy more tail wags, cuddles, and joyful years together.

Giving your pup their daily supplement is simple. Just follow the recommended serving size based on their weight, found on the packaging or below in the next question.
You can sprinkle it over your dog’s food or mix it into a meal whatever makes it easiest for your pup to enjoy. For the best results, use it consistently every day as part of their routine.
If your dog has any specific health concerns, we recommend to always check with your pet’s vet before starting a new supplement.

Many pet parents notice fresher breath, better digestion, and a better health within 7–14 days. Long-term benefits, like joint support and gut health, keep improving with daily use. No matter your dog’s age, it’s never too early or too late to start.

Our dog supplement works by supporting the good bacteria in their gut microbiome. It's normal for their stomach to take a few days to adjust as it adapts to this positive change.
If you notice any mild upset that continues for more than three days, we suggest giving half the daily amount for one week. This helps your dog's system ease into the new routine.
Refer our complete guide on how to introduce our all-in-one dog supplement.
