Zeus medical bills

Hello Zeus is my son dog who is living with us while he is in the Army. He has been struggling with unknown lymphedema in his chest cavity he has been to the vet we need help to pay for his medical care. Zeus is a great Pit-bull very special to our family he loves the kids, is very easy going. When he retains fluid it is hard for him to walk and he is in pain. The vets at U of M have been great they just have no idea about what is wrong with Zeus until they are able to get a special CT scan and a larger surgical biopsy of the area.
