It took Brittany almost 6 weeks to get the 'down' command, this week she finally got it, I had a few liver treats and had her sit and then down and down she went, finally clicked with her. She also refuses to sit on hard wood floors, our entire apartment is hard wood except for the run in the living room, so that's where I have her do it. But now she won't get up, she stays in the down thinking she will get more treats
