Urgent Help Needed for Smitty's Vet Care

I am sorry to have to ask for help, but Smitty needs it and I’ll do anything for him. This morning, when I took him out to do his morning business, I picked him up to bring him back inside, when he suddenly started having a massive seizure. This has never happened before and I was terrified. It went on for several minutes, at which point my roommate heard the commotion and we all rushed to the vet. Fortunately, on the way there, the seizure finally stopped. He is at the vet now, staying overnight for observation. As of yet, they do not know the cause. Up to now, other than being blind and having arthritis, he’s been exceptionally healthy for an older dog.

However, this unexpected vet bill is going to be about $900. If anyone is able to help contribute to this expense in any way, Smitty and I would be incredibly grateful. Thank you in advance to anyone who is able to help.
