Help us save Blanco

Our Blanco is not doing good at all. We are in the process of running tests on him to see What is wrong.
so far all we know is that his liver has shrunken.
His skin is falling of his paw pads.
He gets bilisters that pops and get bloody all over - even in his eyes.
He has a gnarly infection in his ears that won’t go away and his ears are filled with pus.
We have for the past two months been running to the vet and are finally about to do a  biopsy to understand what is really going on. 

Neither one of us have the money to pay for it and we have already had friends helping us out and we are so grateful but it’s still not enough to cover for the rest. 
we are heartbroken. We want blanco to get through this and any help we can get will help. 
He has gotten severely worse in the past couple of days and we are really worried that he won’t make it. 

Even if you share this it helps. 

Thank you everyone
Terin and alex
