This video shows tiny, three-week old Tebow learning how to walk and bark. Tebow is still working on his lower body strength, so he ends up dragging himself quite a bit. He’s certainly determined though. His bark sounds less dog-like and more bird-like, but he doesn’t let that stop him from practicing his vocal exercises. It’s hard to believe that he’ll grow up to be a large, imposing (but still cute!) Bulldog. The video is 5 minutes long and I only expected to watch about 15 seconds, but I ended up watching it all the way through…twice.
