Sorry you & Charlie have had a disaster
Trust me, it'll grow back.
Max had to be shaved when we got him as he was in a bad state.
If you need any re-assurance I can post some pics.
(He looked like a dalmation at first but it has grown back lovely
)
He is now only trimmed with scissors & a coat king though.
Try not to be too upset, sadly Charlie is not the 1st & wont be the last with a bad experience at the groomers. But I'm sure he doesn't care what he looks like
