Agree. Skip may have had a little slip that you didn't even notice and now he's being extra careful.
Our Mario was 9 when he had his LF amp and we got him 6 weeks later. He could not manage at all on our lamiate and we quickly put down non-slip carpet everywhere.
Joshi had her RF leg amputated when she was only 8 months old. We got her last July when she was 15 months and she has had zero issues with any of our laminate/hardwood flooring and the vast majority of the carpets were removed shortly after her arrival.
Perhaps it's an 'age thing'
Skip is older, as was Mario. Joshi is a carefree, not-quite 2 year old.
