Hi, I am not sure what advice to give, but I couldn't just read this and not say how utterly saddened I am for your mother. She must be so shocked and traumatised by what was a terrible end for her poor dog. She was trying to do such a kind thing after all the heartache and expense of the attack - please tell her i think that her dog was so lucky to have found such a beautiful kind carer, and to try and focus on the love and happy times they shared, rather than this sad ending.

No actions will bring her beloved friend back, but the grooming salon absolutely have to be made aware how serious their negligence is. I think a formal letter from the vet and perhaps yourself (as I am sure it would be distressing for your mum to have to relive this) would be at least a step to ensure this never happens to anyone else. In this age of internet reviews etc, it would be very easy to put any prospective clients off using their service, so they should be 100% willing to cover costs etc if they don't want negative feedback. Mistakes happen, but this has been enormously tragic and they must deal with it appropriately or face the consequences.

I just found out today that my Labrador has cancer and it is devastating to face losing him. Huge hugs to your mother, I feel and share her pain xxx
