It depends on what couplers you buy, but a majority of them are made so that they will never get twisted or tangled. Are the dogs use to walking beside each other, do they both go the same pace and do they get along when they do so? I use a coupler for mine and I think it is a great training tool, it teaches the dogs to work together since they are connected. I got mine off of ebay and I am very happy with it!! |
