Hi all, First day on this forum. Seems like there is loads of good advice here and lots of friendly helpful people. We are getting a puppy in the New Year and would like to train him to use an indoor toilet as well as go outside as we have a little boat and we want to train him to be ok overnight down in the cabin with us in the future. We've looked at portable toilets and they all seem to be covered with fake grass which looks like it could be chewed and swallowed - and therefore not safe? I've searched online for toilets which use a cleanable 'mesh' rather than a fake turf, but not found anything convincing. We could use a pad, but we would rather something we could clean and reuse to cut down on waste. Does anybody have advice on fake turf which cannot be chewed, or other options we could consider?
