dog mouthwash – Complete Review 2025
The dog mouthwash from Arm & Hammer has quickly earned a reputation among pet owners for its ease of use and effectiveness. In this complete review, we’ll dive into how this product stands out in the world of pet oral care, focusing on both real results and what sets it apart from competitors.
This tool is a liquid dental rinse designed to be poured into your dog’s drinking water, making daily dog teeth cleaning a hands-off experience. According to PetSmart, the primary goal is to offer a gentle yet effective method for freshening your dog’s breath and helping reduce tartar buildup, no brushing required.
Thanks to the baking soda formula, it also helps maintain that fresh dog breath without detergents or harsh additives. The Arm & Hammer line is widely trusted for pet safe mouthwash options—making it ideal for families seeking a healthy addition to their dog dental care routine.

Key Features of the dog mouthwash
- No-brush convenience: This dental water additive can be poured directly into your pet’s drinking bowl, providing fuss-free dog dental care. No toothbrushes or flavor battles needed.
- Baking soda enhanced: Leveraging the signature Arm & Hammer baking soda, this model not only freshens breath but also supports tartar control for dogs—reinforcing everyday pet oral hygiene.
- Odorless & flavorless: Many dogs turn up their noses at scented products, but this tool’s odorless water additive formula ensures dogs drink without noticing any change in taste.
- Calcium fortified: Added calcium helps support strong tooth enamel and boosts the value of using this dental rinse every day.
Real-World Performance Testing
During testing, the dog mouthwash proved exceptionally easy to use—simply add one capful to every 8 ounces of drinking water as directed. Dog owners reported noticeably fresher breath within the first week, plus some reduction in visible tartar after three to four weeks of consistent use.
Because the solution is a pet safe mouthwash, dogs showed no hesitation about drinking their water. The odorless formula excels here, as it avoids the common pitfall of altered drinking habits that often occurs with strong-tasting dental rinse options.
Testing on older dogs indicated modest improvements in gum health, although heavy tartar remained (regular veterinary cleanings are still needed for severe buildup). While this product effectively supports daily dog dental care, it shouldn’t be seen as a substitute for professional cleanings.

One other benefit observed was better acceptance compared to traditional tooth brushing methods—especially for pets anxious about oral care routines. For stubborn odors or more advanced dental issues, you may want to consult your veterinarian.
How It Compares to Alternatives
Compared to similar dental water additives like TropiClean Fresh Breath or Nylabone Advanced Oral Care, this product stands out thanks to its dual-action baking soda and added calcium. It’s also less likely to be rejected by picky dogs, since it’s both odorless and flavorless—a big win for sensitive pups.
Price-wise, it’s mid-range, making it an attractive option for those wanting reliable dog dental care without overspending. Some alternatives offer larger bottles but may lack the potent baking soda formula that Arm & Hammer is known for.
According to Chewy.com user reviews, this tool consistently outperforms flavored dental rinses when it comes to acceptance and ease of use in multi-dog households.
Who Should Buy This Product?
This tool is a perfect match for busy dog parents who want to maintain their pet’s oral health without wrestling with brushing. It’s especially great for small and medium breeds who are prone to tartar, as well as for rescue dogs unaccustomed to traditional oral routines.
Elderly dog owners and those with physical limitations will appreciate the convenience of simply adding an odorless water additive to their dog’s daily routine. However, those requiring intensive tartar removal or dogs with advanced dental disease should consult a professional—this model is preventative, not curative.
