Medical help for our Puppy Jagger

Will you please pray for a Christmas Miracle for my dog? I'm so heartbroken my sweet dog who is only 4 years old became ill 3 days ago. He went from being his happy, fun, sweet, loving, barking, excited self to being on his death bed. I took him to the hospital last night they ran all bloodwork took xrays and found out his red blood cell count is low and he's only producing baby red blood cells. No obstructions or anything visible in the xrays. That was $600. And still no clear answer. They wanted to keep him ovet night and do a blood transfusion for $2000. I'm so devastated I don't have that kind of money. I brought him home praying for a miracle and for my oldest son who flys home tonight to get an opportunity to say goodbye. I am praying for a Christmas Miracle that this sweet dog who is nothing but pure joy to our family, and my 6th child will some how recover from whatever illness this is. I can't even come to terms with this I'm in shock please pray, send good vibes to my sweet puppy. Thank you!
