Thank you Rouen, very good points, I will remember those
. I guess if I think like saddle packs on a horse, I would on the right track with back packs on a dog?
With dogs you want the weight on the shoulders, not on the back. Their backs are not strong enough to withstand a load. You also dont want anything riding directly on their spine this is why a well made pack will sit more forward and have paniers on either side. A good pack also allows for proper movement.
Dingo's pack is a Kelty Chuckwagon. At the time I bought it it was the only one locally available.
You can see it sits forward, I'd prefer it to sit more on his whithers but it's not likely to cause him trouble where it is.
Ruffwear has put a lot of work into their designs, the approach is what I consider one step better than the Kelty.
You can see that pack sits on the dogs whithers, the weight is on the shoulders and supported by the front limbs. There also appears to be no interference with movement.
If you compare those two to the Outward hound style;
You can see the weight is on the dogs back, there is no structural support for the load where the pack is sitting. The position of this pack likely allows for a lot of play(side to side movement) as there is no support to stop it from swaying.
