First about walking 3 dogs:
Lady usually has Lee in the left and Phod and Emma in the right, however she couldn't do that and take a picture if we were all in one hand so for picture purposes she put us in one. Walking 3 is different and we tend to go short distances (like 2.5 km instead of over 3). As for what happens when we decide to go different ways, which happens about 1x a walk, it includes a lot of swearing, tugging and calling our names. We haven't managed to pull her over yet. For the most part we aren't bad walkers.
Cause it was so nice we are playing outside a lot more. This also helps make up for the fact our walks are shorter.
