Hi everyone, thanks for all the suppport. My dad came home and we went to the vet.
The vet is sending out blood to be tested but he was able to do a test that showed his platelet, red blood cell, and white blood cell counts are extremely low. This explains his bleeding and lethargic behavior. Yesterday however, he was acting perfectly normal.
The doctor suspects one of two causes but have to get blood work results back
1) Some type of tick disease
2) An autoimmune disease that has developed and has reached its breaking point
They gave him antibiotics and steroids to try to treat both possible problems
The blood test results should be back tomorrow.
