My girl is 13m, and has only had her nails clipped once at the groomers.. tbh she doesn't need to go to the groomers for her coat as she is double coated, and loved her nightly raking, and her coat is is good order.
Obviously in lockdown no one has been cutting nails. But hers don't look terribly long, she's not catching them on anything. We have a mix of good long walks every day.. some on pavements and a good romp off lead on fields. As a first time dog owner..exactly WHEN do they need doing? They look ok to me and she isn't clacking on the wood floor.
