We use the snowplow on our atv to try and keep something scraped for him. I keep telling my hubby I’d like to have a kids wading pool in the garage filled with dead leaves (his favorite thing to go on), so I can just let him out into the garage. hubby won’t go for it - yet. :)
That is a marvelous idea!
They do have litter boxes for dogs. Maybe one of those instead of the pool? You could still use the leaves instead of the litter.
