My Jax is a a little over a year old. He’s vision impaired, but not totally blind, due to a congenital issue with his eyes. What worked well for him was confining him to a playpen with a grated pad holder during training. Because he’s small (just under five pounds) — which makes him more susceptible to injury — he’s in the pen whenever he can’t be supervised, so it’s easy to return him to the pen to go potty on a regular basis.
This is the kind of pad holder I use.

The best things about this style of pad holder are (1) he can’t chew on or rip apart the pad, which he loves to do, (2) it’s very stable, so it doesn’t slide around on the floor the way the first (flat) pad holder I tried did, and (3) it’s somewhat enclosed, so Jax very quickly learned where to go. On the down side, it’s not very large. It’s plenty big enough for Jax, but it would probably be too small for a dog over seven or eight pounds. And sometimes, when he’s pooping, Jax will walk a step or two too far and poop just outside the “box.”
