My Dog is Not Doing Well

2 weeks ago he fell down the stairs and we brought him to the vet. After bringing him in we found out he had a bacteria infection in his liver potentially from a UTI. Weeks gone by and he started yelping on the way home from a trip. We brought him directly to an emergency vet. it looks like it has spread to the second kidney. The little g is currently in the hospital being taken care of.

please say a prayer.
