I am so sorry, @
lattiee.
I know it sounds easy to say, but the kindest thing to do for Boogies is let him go. Have your vet ease him out painlessly.
If the bladder stones moves and blocks his urethra like it sounds like it's about to, he will fade quickly and very, very painfully. I went through this in May with my baby Scooter. I took him to the vet after he peed blood twice. They were not certain at the time what it was, and wanted him brought back in the morning after putting him on antibiotics. His vet visit was at 5pm. I held him on my chest and he faded very quickly. I sent my wife out so she didn't have to watch. I hoped he would make it but he passed just after 9pm and it hurt very, very much to watch him suffer. Not nearly as much as it hurt him.
Again, I am so sorry. Boogs needs you to be as strong as you can be for him, but a bladder stone surgery is very risky for a male pig and if it lodges he won't survive it.
