Dumbbell sizing

After doing quite a bit of work to help Dragon learn to pick up his dumbbell straight (behind both canines, and not sticking out in front of one of them), I was concerned that he still wasn't consistently able to do it. I noticed that he was more reliable when the dumbbell was held in the air or laying on the carpet than on a hard surface, and I wondered if perhaps the bells were too short. I took a video:




And I captured some stills from the video:











Yes, it does look like he is hitting his nose against the floor as he picks it up. Poor guy! This dumbbell has bells that are 4 cm high, and the bit is 4 cm long. I have ordered a new one that is the same length but 5 cm high. Hopefully that will solve the "crooked pick-up" issue. (1 cm is a big difference when you're a tiny dog.)
