Help save gunner from Kidney failure

This is my sweet boy gunner. For the past week he hasn’t been eating and excessively drinking water I took him to the vet and got a few medications for him he wouldn’t take his medication and it’s only been going downhill I didn’t know what else to do but i decided to take him back today for x-rays and some bloodwork.. when the blood work came back I didn’t know I would get hit so hard with my one year old dog has kidney problems. I was told with my budget which was very low that they would be able to send me home with some fluids that I would syringe in his back as well as a few more pills.. he will not take his pills and he hasn’t For the past week I was told that he could either have kidney failure or a Kidney disease that he was born with this is the worst thing I had to hear. I was also told since my budget was so low that the treatment they gave me will probably not work that he needs more immediate  serious care. He needs to be sent to the emergency vet where he can stay a while and monitored so they can figure out which one it is.. I do not have the funds to help him and I really need your help please consider donating to gunner to help us get us to the goal to get the help he needs..
