Help Koba get the medical help he needs

My name is Cassandra and I am trying to raise whatever I can to help my sweet nephew Koba! He is an American Bully, he's the most loving and kind doggo you'll ever meet, has never gotten aggressive towards anyone, loves to play with his brothers and family! Recently Koba has been having bad symptoms like bloating, nausea, diarrhea, no appetite, heavy breathing and shaking. We took him to the vet where they ran tests, we are still left with no answers and our wallet is drained.

There is a lot of more testing and imaging needed to find a diagnosis and treatment to follow. Unfortunately it is not something we can afford at the moment and we are trying our best at home with him but he needs professional help. Anything and I mean anything helps ! Thank you God bless !
