Similarly, she explained, life would have been so sad for Nina if she’d lost Gus. “Nina's a bit more independent, but she would have lost her play companion,” Birster said.
“It was 1,000 percent worth it for us to keep them together,” she added. “And my husband and I are completely in love with them and can't imagine life without them!”
Life has been a joy ever since for Birster, her husband, and Nina and Gus. The four couldn’t be happier. “They're now 7 and 6. They go running with us, hiking, and we're constantly trying to figure out new puzzles to stump them because they're both so smart,” Birster said. “They're really fun and funny and have different personalities, but they absolutely go together and are a pair.”
