Double Dog Leash

When my wife and I got our second dog this summer, walking them became a royal pain. Neither one will crap in the dog run, so they have to be taken out twice a day. We were faced with the choice of taking them separately (taking twice the time) or taking them together and dealing with the inevitable tangles as each one sees different squirrels or wants to go at different paces. This leash lets us walk the two dogs simultaneously with no tangles. Thanks to the riveted connectors, they can cross back and forth to their hearts' content, with no adjustment necessary on our part. It looks like several companies make these, but I couldn't find a link for the exact kind we use. The site below promises its version can accommodate three or more dogs.
