After Princess had her vulva nicked by a "butcher groomer" (<--I call her that due to the way she cut the hair actually) and I wasn't even told, I wouldn't put anything past anyone!
After months & months I have come around to trying a new groomer & I actually do like her. Princess was terrified to even go in there & the whole time the groomer and I talked (a looong time

) she shivered in fear. But as soon as she put her hand on Princess to caress her face Princess stopped
immediately. Also, when she was clipping her belly a time before Princess was so relaxed she almost fell asleep!
I was livid with the first one & would rather Princess look like a rag muffin with me grooming her myself. In time, and lot's of research and online review reading, as well as visiting with the groomer several times before, (it's a boutique, too), I decided to give it a shot. To each their own, but try not to lose all faith forever if you don't want to groom her yourself. The right one may just come along.

Just like in human medicine, or a restaurant or anything some are better than others. And some are much worse.
