Yorkie “Chewy” needs surgery

Our 10 month old lively Yorkie “Chewy” needs to have an endoscopy and surgery after ingesting an unknown object. :( we've gotten 2 xrays for him and spent so much on the xrays itself that we can't afford for the surgery.. We've tried going to a charity veternarian and consulted with several vets as well.. The charity vet could not do the procedure since their endoscope is broken and private vets are extremely pricey. Please help Chewy get his surgery! We're grateful for any help at all! Thank you all in advance!
