Help pay Finns giant vet bill

Long story short, Finn went into the vet with a urinary tract blockage. They got the blockage cleared but he passed nothing but blood for a few days and needed an emergency transfusion. At that point the bill was already $3000 and it was another $2000 for the transfusion to have him back home but all in $5000 is a ton of money I don’t have. Finns only 4, he’s got a long healthy life ahead of him now. Anything helps
