Dogwalk Slat comparison

Here is a picture comparing my dogwalk slat from home with the dogwalks at the training field. The lower slat with the blue and white paint is mine from home. The picture to the left is our clubs new dogwalk. The slat is very high compared to my home slat. The picture to the right is the old dogwalk our club still has. I video taped her tonight on the old dogwalk. I didn't see any sips and I let her run the new dogwalk once and I saw a skip. (skip defined as holding her leg up). I'll try to post the video tomorrow, I'm to tired tonight. But I think this shows the difference in heights pretty well. Which could be why I'm seeing no skip at home and a skip at the training field. Ive been using the new dogwalk. ( click the picture if you want to see it bigger)
