I had Charlie trimmed last friday & I wasn't too keen on having him clipped as I might eventually show him so she just tidied his feet & legs up, took the fluff off the top of his head and trimmed the end of his tail (it was really long!
) & stripped some of his puppy fluff off the sides, as Maggie said, not all of it was ready to come out, as he's only 5 1/2 months but it does look alot tidier now & you can see his adult coat coming through.
I'm not experienced in the grooming area but I would have her hand stripped. I took Charlie back to his breeder as she's a groomer & it cost me £20 for a bath & trim, also she picked him up from the house & brought him back after. She normally charges about £25 - £30 but only charged me £20
Good luck with her trim on tuesday, looking forward to seeing some pics! She looks gorgeous in the picture you posted btw
