we have lupis for our dogs, they are like a sled harnes but smaller. They have worked wonders with our lab Chester. Chester was never walked properly with my parents, they took him for runs, so his walk manners were horrible. When we got them after my parents separated (long story) we got lupis for the both of them and now Chester is learing manners. It tugs on their chest without hurting them and teaches them not to pull, we love them. Bobbie who is a terrier does not like hers so much but has gotten used to it and it is so nice to walk her with it.
