Hello and welcome to YT!
I searched for quite a while before I found a groomer that I was happy to bring Pebbles to. The groomer trims around her face and does her nails. She lets me stay in the room and hold Pebbles while she works. She finishes off by giving Pebbles a kiss on the top of her head and a treat
The best thing to do, I think, is ask around your area and then visit recommended groomers and explain what you would like done. I think it's important to visit before any work is done so you can check that you will be happy to leave your pup there and that they are happy to follow your instructions. Best of luck and post pics of the new haircut
