Mars’ Greenies dog treat brand is leveraging college basketball's biggest stage for a promotion focusing on canine dental health. 

The company is teaming up with the University of Connecticut Huskies (of course!) alongside alumna star player Diana Taurasi to “remind pet parents to care for their canine teammates and be the ultimate defense for their dog's oral health,” according to a release.

Even Jonathan, the costumed UConn Huskies mascot, will be sporting a custom Greenies Mouthguard as a reminder that champions needs to protect their teeth.

According to the Journal of Veterinary Medical Science, an alarming 80% of dogs show signs of dental disease by age 3, which if overlooked, can lead to pain, disease, and impact on their overall well-being.

Dog owners are being asked to take the pledge to “Be Your Dog’s Mouthguard.” They are invited to visit GreeniesBeYourDogsMouthguard.com to take the pledge. And if either of the UConn men's or women's basketball teams wins the NCAA national championship, pledge-takers will win free Greenies Dog Dental Treats.

"Defense is essential for winning championships, and that matters at home, too," said Mindy Barry, chief marketing officer, Mars Pet Nutrition North America, in a release. "If we can use this moment with the UConn Huskies to rally pet parents around their dog's dental care the same way they rally behind their favorite teams, we're doing something meaningful for dogs everywhere."

Greenies dog dental treats fight plaque and tartar buildup, freshen breath, and support healthy gums and teeth, which can help support oral and overall health, according to the company.

The brand is also offering the Greenies Canine Dental Check, an AI-powered tool that helps monitor a dog's dental health using a simple smartphone photo, to help pet parents stay on top of dogs' oral care between vet visits.
