BLD, so very glad to hear that Lex is on the mend.
Thank you for posting everything that happened - a big eye opener for folks hopefully about "worst case" unexpected disasters.
Also, thank you for being honest about your financial sits re Lex's surgery. I get exactly where you are coming from.
When my Rosie had bloat 5 weeks ago now, her diagnosis came at 2am with a vet saying down the phone "we have to operate now, or euthanase... and by the way, you are looking at $4K for this - can we have your credit card number for the deposit?" Yes, for that split second you do really have that horrible thought "$4K???!!!", but then you suck it up, and start figuring out just what has to give for the next 3/6/9/12 months in order to make it so.
So, thanks for sharing Lex's story, and so very glad to hear that he, like my Rosie, is on the mend!
