Our Story

We’re bacteria whisperers & dog worshippers


We’re dog people

Team TEEF! believes that dogs are truly amazing creatures who make our day-to-day lives exponentially better. Like most dog owners, we would do pretty much anything to help our fur babies live their best lives.

We’re determined to bring this product to all dog owners so that nobody has to see their pup suffer the pain and health issues that come with dental disease. We strongly believe TEEF! is a game-changer in dog dental care… and we hope you will, too!


It all started with a rescue dog

Saved from a shelter at 10 years old, Tinzley had multiple health conditions that all traced back to neglected dental care. Luckily, she was adopted by Dr. Emily Stein, a UC Berkeley and Stanford-trained scientist with an extensive background in microbiology and immunology… and a soft spot for older dogs.

She knew immediately that oral bacteria were the source of Tinzley’s eye and bladder infections, skin irritations and lack of energy. After 4 months of antibiotics, 21 tooth extractions and thousands of dollars in vet bills, Tinzley was finally healthy again. All these issues stemmed from the connection between the mouth and body.


The Research

Emily screened hundreds of ingredients until she found a combination that does what no other product does: create a healthier mouth! One that strengthens the good oral bacteria that protect against gum inflammation and tooth decay.
