I've raised £1700 to pay for Brandi's operation

My childhood dog Brandi has a ruptured ligament in her knee joint and needs a potential life saving operation so she can get better soon and have a better quality of life. Unfortunately I lost my dad 6 months ago to motor neurons disease so my mum can't afford the treatment.
Shes been my bestfriend since I was 10 years old, she was a birthday present for me from my late father so she is one of the last things I have that reminds me of him. She's a beautiful border collie full of life, she loves walks and play time please help her enjoy the rest of her long life.
Shes only 12
Shes got sweet hazel brown eyes
Shes red and white with bits of black
Shes full of life
She loves adventures
She loves people
She loves cuddles
She loves her teddy
