I know this has been touched on before, but thought it was worth sharing my musings and having more valuable feedback.
I have five dogs, as most of you know. When we walk, my daughter walks two and I walk three. Two of mine are the rotty x shepherd pups, who are now four months old and out and about. They are doing beautifully off leash at the dog park and on bushwalks.
They tend to go haywire out on a leashed walk, zigzagging and so on. I have tried walking them solo, to give them a bit more of an idea of walking next to me on a loose lead, but they tend to cringe at any pulling on the collar (just a normal, thick webbing collar). To solve the group walk thing, they have normal harnesses and a double lead, which is like a V, with swivels, which then goes into one lead for me to hold. This has worked well as far as they are pulled towards each other, by each other and they seem much more relaxed with the whole body feel of the harness. Of course, as they have gotten more confident, they are starting to pull, which I want to avoid before it becomes a habit (they look like a really cute version of that three headed dog in Harry Potter, except with two heads, lol).
My first thought is to go with a couple of harmony, or balance harnesses, which supposedly avoid the pulling issue of normal harnesses. I would still use a double lead going into one. The other choice is the sporn style harness, but I tend to think they will find the tightening and loosening effect disconcerting (they stop if they feel nervous). I don't think a check chain or combo check and web chain is a good choice for them either.
I'd be really interested in what others think - especially what their experiences of walking/training multiple dogs has been. I am open to spending individual time with each pup of course. Compared to my other pup (five month old standard poodle), they seem 'slow' to get the walking on a loose lead at my side concept. It's probably down to me not having had dogs with this particular kind of response before.
Thanking you all in advance for your thoughts,
