thanks all! It's funny how serious he looks in this picture. I told hubby he was trying to look polished, when we know the very silly, rambunctious Marley all too well.
Teehee, after I posted it, I was wondering if anyone would notice the knots.
Yes, we put them there when we were training him months ago. If we would step on the leash to grab him or keep him in one spot, it'd slip from our feet. The knots helped us hold on the leash while doing whatever we were doing. Now they are just there but I guess if we ever need them we will have them.
