Osiris and Riff Rat are an unusually trusting couple; the 3-year-old Dutch shepherd therapy dog lets the 3-month-old rat crawl into his mouth and clean his teeth – Dutch shepherds are famous for their obedience and train-ability. Riff Rat was rescued at about 4 weeks of age and nursed back to health with a syringe.
“Riff Ratt really likes licking the inside of Osiris’ mouth. I’m sure you all are wondering if we’re afraid Osiris will eat Riff – NOPE! Osiris has helped foster and care for dozens of animals and he is the gentlest dog I’ve ever met,” writes their owner on the @osirisandriff Instagram.
