I've raised £800 to help fund an operation for our husky Imalah

My imalah is 11 years old now and has grew up with my children she is an amazing member of the family, over the past couple of years she has suffered with seizures and just recently they have been more frequent the one she had about 6/8 weeks ago triggered a season which she had not had one of in quite a while . A few days ago she had another small seizure and I'd been noticing wet patches where she lay. I took her to the vet yesterday and after scanning her stomach they found she had Pyometra and her womb is full off puss she really is quite poorly it is life threatening and needs an immediate operation ,the vet wanted to keep her in and operate first thing but when I asked how much it was and if I could spread it over a payment plan as I am on benefits st the moment they said no and sent us home again strssing that the op needs to happen soon preferably no late than Friday. I spent the afternoon and evening on the phone with various charitys and they are all struggling and cannot help with something so large a lady from the RSPCA is going to speak with the vet on my behalf today to see if she can get them to help more but so far iv come across nothing I used to be with the PDSA for help with funding but they have stopped it all nation wide.
So if you could help in any way I would be so gratefull she has been the most amazing funny dog and we all love her so much
Thank you
