You can easily clip another leash to each one. However, these will not be retractable, so you should probably take this into consideration.

I have two 80lbs dogs and they always like pulling me, but I've never had any issues with this double retractable dog leash so far.

These retractable double leash for dogs does not come with poop bags, but you can probably find a way to attach it to them.

Of course, using a leash to walk two dogs, two small, energetic, and dare I say - naught dogs, come with issues.
They do indeed get tangled at some point if I let my dogs really loose, which they tend to do as they keep running around. But It's my fault, really, not the leash's.
6- Can I attach a poop bag collection?
You can If you're creative enough, but these dual doggie walking leashes don't have a dedicated spot to attach poop bags.
7- How wide are the clips and the ribbons?
The clips are about 2 1/4 and the tapes are about 1/2 inches.
8- Is there a small double retractable dog leash?
There is no small version if that's what you're asking, but I use it with my small dogs no problem whatsoever.
9- Is this dual doggie pet leash heavy?
Not at all, or at least not any heavier than two leashes together. I walk my dogs pretty much every day with them and have never thought they were heavy.
10- How solid is the retractable function?
The retractable function is pretty solid and I didn't face any issues with them so far.
