Help Sasha go MRI

Sasha is young dog who has been in a foster care for more than a year. He was just a puppy when he was rescued from the streets of Romania. There are days when he acts normally, feels good, plays and eats just like any other dog. But also he has bad days with lots of pain.
This is happening because Sasha is sick, it is not quite clear what it is: a tumor or a bone formation on his brain that causes the pain he feels and all the other symptoms, including the bad sight. Unfortunately, we have not managed to do an MRI, we had not the money to pay. It is very expensive here in Romania, 1000 RON (around £300).
He gets treatment (painkillers) every month without which it would be much worse for him, but until we know for sure what he's suffering from it could any time get worse. Nevertheless Sasha has a chance to live a normal happy doggy life with the correct treatment, but for that he needs to be taken to have an MRI. Let's help sweet Sasha having a happy life without pain, the life that any dog deserves to have!
