For example, I have never come up with a good way -- other than age -- to stop a Basenji pup from lunching on shoelaces. If you have an idea let me know!
You could buy a pair of shoes with velco (sp) fastening, at least for use when you are with the puppy !
Or live in Sketchers as I do ! Excellent for the back and I'm sure they are not restricted to this country.
