Mensch on a bench dog photo

My local pet store does pictures for holidays. $10 per picture and it goes to charity. I am not religious – I “celebrate Christmas” in the way that doesnt mean anything except we decorate, have dinner, give gifts. So really just the commercial aspects of it. The pet store is doing Santa photos and Grinch photos so I’ll definitely do those. And they have one day where they’re doing Mensch on a Bench photos at a location in a city with a strong Jewish community. I thought about buying a Hanukkah bandana and taking my dog for a photo. I don’t really do anything with the photos except post on my Instagram story and then put it on the side of my fridge. Is it offensive to do the mensch photos when I’m not Jewish? I’d just like to support. Thank you!
