As of 3 AM this morning I was well aware that Shilo felt better. He climbed into bed, started nuzzling me with his nose and paw-pawing on my neck.
So the good news is the medication is working but the bad news is it MUST be his heart that is failing. :( And that breaks my own heart into a million pieces.
Late tonight, I will speak to the vet who will have the blood test results and instructions on what to do next.
PRAYERS for sweet Shilo.
