Is this hop/skip something to worry about?

My bichon started doing this little skip on every walk where he lifts his right leg. He started it after a short hair cut at the groomers so I assumed he was feeling the wind on his skin. But it continued and he’s been doing it consistently for months. Idk why I didn’t think it could be a problem I honestly thought it was a super cute quirk but I googled it and apparently it’s a hip problem? He’s never shown any sign of pain!

Has anyone had the same with their bichon before?
