I can walk all 3 together or individually. These days I take the youngest on a long walk and when we get back all 3 go on a short walk.
If you got your dogs to walk on a loose lead you would have a better time than being dragged around. Personally I prefer a prong on a puller.
I think it's a big mistake not to let dogs get used to being separated. My boss & his fiancé got 2 puppies their about a year and a half now big time separation issues.
