I've raised £500 to My dog's ear surgery.

Hello I would like to ask for little help for my boy. He got ear hematoma which means he got blood in his ear flap and best solution is surgery and this cost around 500 £. Which I can't afford right now I wish I could but last few months I've spent a lot of money for unexpected things and this one came last and hurt me the most 🙁 So I just want to ask if you can help.. If not then I understand.. it's not your problem it's mine. I just trying everything what I can and maybe in this world are still some good people which will understand me. So please if you don't like it then leave it and if you would like to help I just will be very happy and grateful. Thank you.
