We're hoping to find a Boxer pup this summer. We have a foster terrier under a year, thinking maybe we'd adopt him. The pup is a handful and can even crawl up a Plexiglas gate, and get into another room. Separation anxiety is also an issue. Has anyone had these two breeds together in a household and survived? I'm thinking too smart, and too wired may be a problem, and I'm not getting any younger. Our Boxer would open drawers with his tongue when he was a puppy. We've never had a two dog household. Maybe just two Boxers.
