Help with Bolt's Medical expenses

My baby Bolt a year and a 1/2 old yorkie poo soooooo full of life the happiest little guy you've ever seen Is not doing well at all he is being kept at the ER Where they can monitor him 24/7 in Doggie ICU:( Unfortunately they're not sure what is wrong with him they are running all kinds of test an doing their absolute best to help my boy and figure out what is going on with him. He was perfectly fine at bed time one night and woke up Extremely ill ...NOT himself! I just knew something was wrong i rushed him to the vet where they rushed him to the emergency Room To find out that he is bleeding internally so now they are doing everything they can to figure out What is causing this ?! so that it can be stopped and he can be saved and he doesn't lose his little life at such a young age :(..... At the moment he is on IV fluids not able to eat or drink because he can't keep anything down :( Antibiotic and a medicine to help stop the bleeding or at least control it They have done a ton of blood work , X-ray , heart worm and tick scan , CBC test And a ultra sound but unfortunately still no Answers.... All I want is for him to get better and be home with his family but with wanting the BEST for your animal/fur baby comes Extremely large overwhelming bills :'( At the moment his bill is around $3000 and climbing every day ......So please If you can find it in your heart and donate something anything ......every little bit counts
