Maddie never wears a leash inside and very rarely ever wears
one outside either. When I take her to the vet, I carry her
in and then she just sits in my lap. When we're camping, she
only goes on a leash, if I can't watch her, otherwise I just
let her putter around checking things out.

Murph never wears a leash inside, but is always on leash
outside, except the fenced backyard. Anywhere else outside
and he's leashed. Just don't trust him enough not to chase
after something and not listen to me.

Oz wears a leash inside if I'm having people over, just during
the initial greeting, because I'm still working with him not to
jump on people. He just gets so excited when somebody talks
to him. He's mostly on a leash outside of the house and yard,
except sometimes if I feel the area's relatively safe I'll let him
off leash or I'll have him on a long leash but not holding it.

Edited to add: I'm paranoid about leaving collars on, especially
inside the house. Murph got his caught once and I saw the panic
and realized if I hadn't been home he'd have probably choked
himself to death. So collars only when I'm with them.
