Former "Bachelorette" and "Dancing With the Stars" champion Hannah Brown joined Cheddar News with veterinarian Dr. Callie Harris to discuss the importance of your pet's milestones. Brown also talked about her new puppy, Wally, and her partnership with Purina One. "Wally is an Australian labradoodle and is about eight months old now, so definitely still in his puppy phase," she said. "But every day he's learning and growing and it's new and exciting but also can be a little bit stressful."
