omg!
I've only just seen this thread and I have to say I can't blame you for being upset, I gasped when I scrolled down to the pics, they'd have known I wasn't happy if I'd collected them because I would have literally bawled my eyes out there and then.
When Bella had her first 'trim' I cried when hubby brought her home and in comparison she still had lots of hair, she just didn't look like my Bella anymore and for a few hours I have to admit I couldn't even look at her
I'd be really upset if they'd done that to me, don't let them get away with that, it's awful, a bad haircut would be bad enough but there is no excuse to scalp them like that, how can they call themselves professional groomers? Sorry if that all sounds harsh, your story has really wound me up
The good news is that it will grow back and if they're anything like Bella it will grow really quickly. Bella soon looked 'normal' again and I no longer let my groomer do her head (I do it myself when she comes home) but don't let it lie, I would expect a refund PLUS compensation and make sure everyone you know locally with a dog hears about this and doesn't use them.
