Bloodwork is back... kinda
The good news for the other dogs is that Jordie wasn't poisoned. They don't know what the cause of the HGE was, other than no poisons were present in the bloodwork.
I'm depressed, but relieved at that news. Depressed because I gave all four of the dogs a little piece of cheese I was eating (sharp cheddar) Wednesday night. Other than that, the only food he had was his standard wet dog food mixed with a little dry dog food. He's been eating that for years.
Thanks to everyone for their sympathy and support during this trying time.
God Bless!
