Please Help Mischief to walk again

Hi there. I'm trying to raise some funds for my female dog mischiefs knee surgery. I am a beneficiary of three children plus my beautiful girl mischief who I've had for 6 years. She's 10 years old. She has been the most loving loyal protector and best friend to me my 16 year old daughter and my two young boys. We all love the outdoors and Mischiefs happy place is out in the bush or running along the beach.

Sadly due to an injury to her leg she now cannot walk let alone run. She is miserable and after taking her to riverbank vets in otaki we were told that in order for her to be able to walk again she would need knee surgery at a cost of $4000.00 it is a huge amount for me to come up with, impossible on my own and I'm just asking for anyone who could please help me with donations so that mischief can have the life she enjoys back again.

I already have a $1000 bill for the initial x-rays injections sedation and inflammation meds which I'm paying off at $100.00 a week which is a struggle in itself for me and paying off the additional $4000 for surgery isn't an option. I'm asking anyone to please help me and my little family to get mischief the surgery she needs so she can come for walks again and get out and be happy in the bush and beach. Thank you every dollar helps. Any additional info needed from the vets I will happily supply as proof.
