A triple coupler???!

sorry, I'm just visualizing my three coupled together so closely.....
do your pups walk that well together? I have a coupler that I hook up to Archie and Abbey when we're going somewhere - like if we're going to be standing in line for something - but not for actual walks.
I also use it on their harnesses to teather them into their car seat.
For walks I use two four foot long leashes and put them onto a very large padded "D" ring. Then I have Tinker on a six foot long leash so when I have all three leashes in one hand, at least Tink has two feet more to spread out alittle.
When I tried walking Archie & Abbey on the short coupler, when one stoped to pee, the other would pull him/her over!
I so use step-in harnesses, but the ones that click shut are easier, I think.
