My neighbor has a labradoodle, and she is VERY high energy. I have had poodles and I now have labs, and this combination seems to lead to an extremely smart, high-energy dog. That can be lots of fun and that can be lots of trouble!
Have you considered looking into adopting a pet from a rescue group? If you aren't having any luck with the shelters, this could be a good option. I am a foster 'mom' for rescued labs, and the nice thing is that you get to see the dog in a home situation. The dog has been fully vetted, socialized, and get a little training. Most rescue organizations are breed based - you can try a google search to find one in your area!
Good luck! Whatever you do, I'm glad you're getting another dog
