Help BigChomp with Recovery from foreign body

Hello, my name is Tracie, and I'm trying to raise money for my 12-year-old son's 8-month-old puppy, who needs exploratory surgery. This is Big Chomp. He is going on day 5 of not being able to hold any food down. He can eat, but within 30 minutes, it's coming right back up.

I took him to the vet for X-rays yesterday, and they revealed that he has a blockage in his GI tract that isn't passing. The longer he has this blockage, the higher the risk of damage to the rest of his intestines. We have been giving him subcutaneous fluids to help keep him hydrated and hopefully help move things along, but it looks like surgery is going to be his only option. I have applied for Care Credit, Scratch Pay, and loans, but I was declined. I'm at a loss. My three sons suffered the loss of our other two older dogs last year due to traumatic accidents. But Chomp is still young and trying to be strong. He wants to eat and is fighting for his life. We want to give him the best chance, and that's surgery, but we need help. Anything is greatly appreciated and would help out so much. Thank you.
