Well, 3 pups have arrived and now we have 2 more boys and another girl in our pack. I found this great Avidog Adventure Box and decided it would be a fabulous tool for their development. My next door neighbor helped and it turned out wonderfully! The pups can start using it when they begin to walk and explore~about 3-4 weeks. You can read all about it and get directions by just doing a computer search. I will post more pics and a video later, once these pups are ready to explore. Can’t wait!
