Sam's vet bills

Hello all my name is Justus and I am asking for help with my dog, Sam. About 2 nights ago (2/9/21) Sam had started throwing up and continued to do so throughout the night. Early the next morning before our car ride to the vet I also noticed he had trouble going to the bathroom and looked as if he were in pain and struggling to go. After a lot of testing, which included a CPL SNAP test, Giardia SNAP test, Radiograph Consult and Radiology - Abdomen. Sam still needs more testing done and to go see a specialist to figure out what's wrong. With a child on the way, my funds are limited without going into debt. Seeing my boy having this amount of pain and discomfort and not wanting to eat or drink really saddens me and I am trying to not feel hopeless. Sam has not only been apart of my family but he is also my best friend who I love so much. Receiving any help would mean so much to me that words could not explain and I would be forever grateful. The funds would be used to pay for the further testing needed to see what is exactly wrong with Sam(the vet said it could have something to do with his pancreas or his prostate) and to pay for any further treatment afterwards. Sam needs treatment as soon as possible. Thank you.
