Rexy Bear's Medical Fund

Repost from original Facebook post:
I've been an absolute mess the last 24 hours and will probably continue to be for the next week or so. I took my best buddy into the vet yesterday because he's had a very bloated belly for almost a week now and anyone that knows Rex would probably just assume that my little trash bear ate something that he shouldn't have and ended up with a blockage, which is what I thought. I wasn't quite prepared for them to tell me that he has a mass on his spleen that has been leaking blood into his abdomen and it may or may not be cancerous. They also said that if it ruptures any time before surgery that most dogs bleed out too quickly to be saved. Fortunately his surgery to remove his spleen is not too far away. He goes in tomorrow morning to have the entire spleen removed and only after that can they biopsy the mass. It will take about a week to get the results back, but if it is cancerous the odds of it having already spread to the liver is pretty likely. So doggy chemo would be the next step... or do nothing and let him live out the rest of his life... but I'm not sure I could just let my best friend die. Even if it only got me one more year with him it'd be worth the debt (assuming it wouldn't put him through too much pain). Please send my little turd pup all the good vibes that it doesn't rupture before he has the chance to have surgery, for a safe procedure, for negative results on the biopsy, and for a speedy recovery. He and I would both appreciate the love through this really difficult time.

It's really, really difficult for me to ask for financial help like this. I feel very fortunate that I get to travel so much and do so many fun activities, but it's because I do it in extremely affordable ways, save for long periods of time, use frequent flyer miles, stay with friends or in my car, or foolishly put it on credit cards, it's definitely not because I have a lot of cash flow. And I definitely wasn't expecting such a major financial hit like this. I feel guilty for not putting away a little bit of money here and there for emergencies in my fur child's life or for not having pet insurance, but now I know. Preparedness is key. However, that still leaves me without funding in the current situation. I've talked with my vet and gone over all of the possible financial outcomes for all of the testing, xrays, and bloodwork done yesterday, all of the possible incidentals that may come with surgery tomorrow, and the cost of the biopsy. We haven't factored in any chemo costs because that's not a bridge I'm ready to cross yet, and I'm trying very hard to manifest that it's non cancerous. But with all of the immediate bills considered my vet said the low end estimate is $3,000 and that's really all I'd feel comfortable asking donations for since I'd feel absolutely awful if I raised more and ended up not needing it all. I just desperately want my puppy buddy to continue to climb into people's laps (even though he's absolutely not a lap dog), put smiles on my friend's faces, go camping with me, explore, get lost, snuggle with me on rainy days, give me all the kisses when I'm struggling, and be around for a very long time.
