Sadie is a puppy and she stops every few feet. It is a pain but she is learning and when she gets scared she stops and drops!
I have tried the coupler but because she stops so much chewy does try to drqg her so for now no coupler. i did try on day putting the leash on chewy and having the coupler on Sadie... that way I had complete control on chewy and Sadie was just coming a long but it is hard. I hope both your dogs are good walkers. If you have a puppy expect delays!
