Effectiveness is often noticeable within a week, with fuller results after about 30 days of consistent use. Many pet owners have observed fresher breath and healthier gums during this period. Since it works gradually, patience and regular use are important to see benefits. Users should monitor for any signs of allergies or stomach upset when starting, as the instructions advise.

If you use a carbon-based water filter, it might remove the active ingredients, so adjusting your setup may be necessary to achieve the best results. The price is reasonable given the large 128 oz bottle, which should last a while depending on your pet’s water consumption, making it cost-effective for long-term oral care. This water additive offers a convenient, safe, and pet-friendly way to maintain dental health without the stress of brushing, making it a good choice for pet owners seeking an easy breath freshener and plaque fighter with consistent use.

It’s suitable for dogs of all ages and even cats, offering versatility if you have multiple pets.
