Jack is a 25-pound bundle of high-octane joy with a bit of a comedic streak. At six years old, he manages to mix pure muscle with the energy level of a caffeine-fueled party guest, and yes, he’s got a vertical leap that would make a kangaroo jealous. He’s a walk enthusiast, lives for his stuffed toys, and tends to greet every day as if it’s his own personal Olympics. Jack guards his toys with unmatched seriousness, so homes with small children prone to sharing battles aren’t the best fit. But if you want a loyal, endlessly amusing adventure buddy who keeps things hilarious and unpredictable, Jack is ready to apply for the job. Give up your TV—you won’t need it with this entertaining rascal around. Let’s make it official, apply to adopt!
