I too recommend the 2 dog coupler. I walk Simba and Nala with it. We got ours at PetsMart in the leash section. They have one in every color. We got a red one.

Also, if they pull at all - I recommend harnesses, which can also be found in the PetsMart leash section in different colors. Both of mine have one in black.
Simba is fine without his harness, but Nala like to pull. It's amazing the difference on the harness compared to a collar. They also don't choke theirselves on the harness.


Also, get Tori used to walking on a leash and good about not pulling. It'll make walking two dogs much easier.

Although, Since Simba and Nala are complete opposites -- when we're walking it's pretty good. Since Simba likes to go so slow and sniff everything, with Nala's slight pulling and wanting to just walk gets us much farther. They kind of control eachother for me.
