Thanks for spotting this. It's exactly a shop=pet_grooming + pet=dog. I corrected the tagging and added some details.

(I passed it by chance 2 days ago with Mapillary and the shop is still there: https://www.mapillary.com/app/?lat=52.4357172&lng=13.434931000000006&z=17.940755343834773&pKey=1731485580653417&focus=photo&x=0.7603262908559079&y=0.5062054349541161&zoom=0.7192429022082019)
