<human>: My dog was washed and brushed by the groomer about a month ago but as I had my her at the beach and my mum was to mind her for the night I decided to book her in again for a wash and a brush. 

My dog is a rescued mongrel but seems to have a lot of Newfoundland in her and as such has a very thick undercoat. She is a year old and when she was rescued about 6 months ago they had to shave her, so her hair was only just starting to fill out and there are parts of her that where mostly filled in buy undercoat. When I collected her from the groomers they had used a bladed brush (furminator) to remove all of her undercoat completely, they have also given her a sore looking shaving rash around her back legs. She was very lethargic, didn't eat yesterday and had very watery poos. I took her to the vet who gave her antibiotics to help her diarrhea and cream to keep the wound clean.

I'm so upset and angry at the groomers for hurting her and for removing all of her undercoat which has really highlighted just how much weight she still has to gain and made her considerably less cuddly and healthy looking. I just don't know enough about grooming dogs to know if this is normal practice and if the groomer actually did me a favour by taking all the undercoat off her. I know she is such a timid and loving dog that she would not have complained about being hurt or moved around and got excited making grooming difficult.

I'm sorry if this doesn't read well, I'm unusually upset and angered by the whole ordeal but I dont want to fly off the handle if it's just me being an over worried new parent. I just feel like I paid money to have her washed and brushed, not washed and her undercoat shaved and her leg cut [here are some before and after shots, there are 2 of her sad rescue photos incase you dont want to see them](

Can you provide a brief overview of the text?
