Dog Oral Care: Gums Are More Important Than Teeth. Dentist x Veterinarian Developed Dog Oral Gel Certified as "Japan's First*"

AOI Co., Ltd. (Headquarters: Chuo-ku, Tokyo; Representative: Atsuya Mori), which operates the joint development brand "WANSER" by dentists and veterinarians, announced that its dog oral gel "WANSER Hagukismile" has been certified as Japan's first* gel/gel-type dog dental care product containing collagen and elastin.

◆ "Gums" that affect the healthy lifespan of dogs

While "tartar" and "bad breath" tend to attract attention when it comes to oral problems in dogs, from a dentist's perspective, the "gums" that support the teeth are the key to oral health. Approximately 60% of gums are composed of collagen, and veterinarians also point out the importance of daily gum care.

However, few pet owners are consistently engaged in dog oral care, and many owners feel they "should do it" but are unable to practice it. Furthermore, very few owners are aware of "gums" as a target for care, and the importance of gum care is not sufficiently known.

"WANSER Hagukismile" is a gel developed by a dentist who focused on "gums" in response to this situation. It can be applied with a brush or finger, or mixed with water or dog food. It is designed to be easy to use even for dogs that dislike teeth brushing.
