I purchased this new and used it once. I tried to use it on my dog, but I couldn't get him to open his mouth, so I gave up. Purchased and opened on 2025/09/17. Made in the UK, this is an oral care foam for dogs. Online retailer price: 3,850 yen ※ The following is a quote from the product description: ■ Dental Foam Cares with foam. Protects gums and oral mucosa with gentle foam. Controls plaque and tartar and freshens breath. When mixed with saliva, it generates enzymes that lift and dissolve tartar and plaque. No need to use a toothbrush. It's an easy care product that only requires massaging the muzzle. ■ How to use Apply one pump to each side of the gums, then gently massage the muzzle. No need to brush afterwards. It's safe to swallow, and there's almost no aftertaste. A gentle fragrance is faintly released when the foam is dispensed. ■ Ingredients Purified water, glycerin, monopropylene glycol, PGE40 hydrogenated castor oil, potassium sorbate, glucose oxidase, peppermint oil, sorbic acid, geranium oil, ascorbic acid, clove oil, copper chlorophyllin sodium Thank you for looking.
