Otis the Handsome Hound on Instagram: "For those who don’t know Otis’s story yet ~ Otis was rescued from a research breeding facility where thousands of hounds are kept for laboratory use. 💔 After spending a year there, he was one of the lucky few to make it out — and now we’re on a mission to help end animal testing for good. Thank you for caring. Follow @otisthehandsomehound to join our movement of compassion. 🐾 #EndAnimalTesting #AnimalTestingAwareness #RescueDog #BeTheirVoice"
