Comet’s kidney Stone Removal Surgery

Hi guys, I never thought I’d be starting a go fund me but this is an emergency. So my doggy comet has recently gotten sick, he went from a loss of appetite & blood in his urine to being unable to hold his pee.  Took him to the vet and 600 dollars later I found out that he has kidney stones & bladder stones. ): he’s going to need surgery for the kidney stones otherwise if they rupture he will lose his life he will also need to be on a special diet from now on to try to shrink the bladder stones. I’m a college student and have other bills I need to pay & after his current vet bill and future check ups I unfortunately won’t be able to afford this life saving procedure. Any bit helps if you can please donate to this go fund me! Thank you so much for reading his story.
