help my dog

Hi, this is Sasha, a 11 y/o cross breed born in a rescue home, my family brought her home back in 2005.
She is such a loving dog but sadly she has recently fallen ill.
Sasha is constantly gasping for breath and throwing up, she also has big lumps in random places, which are very painful for her.
Unfortunatly I cannot afford to pay for the vet bills on my own.
I would appreciate it if you could help me out by donating any amount. 
Thankyou.
(Roughly)
£50 for the checkup
£100 for the injections she needs
and the rest of the money for any operations, x-Ray's ect that she may need.
If not enough money is raised the money already donated will still go towards her.
Instead of it used for making her better it'll be used to put her to sleep. (costing £100-£200)
