Oscar eye surgery

Please help. My dog needs emergency surgery due to an ulcer, I had saved up £500 already but that had to go on the treatments before and unfortunately hasnt worked, Target is £1800 for his eye to be removed so he can have a happy pain free life . Anything would be greatly appreciated as just want my baby better. He is my baby and I am trying to give him the best treatment for him. Times are very hard at the moment and I would do anything to make my baby better. I work 2 jobs to try and make ends meet but its just not enough Thank you for reading
