Saw a greyhound on an extended lead this morning jumping all over the place at the other side of the park - not a good idea!

When we adopted our girl we were advised NEVER to use an extended/extendable lead as in only 5 or 6 paces they can get upwards of 30mph and so could easily snap their neck when the limit of the line is reached. I suppose it depends on your hound, but knowing that ours can go from standing still to full-on zoom in the blink of an eye I wouldn't risk it.
