The blood sample came back with normal blood sugar. ????
So, while the urine didn't indicate infection, we're treating him for bladder infection and doing everything possible to convince him to eat. So far I've fed him out of my hand, some roast beef and some spoonfuls of easy digest mush canned food.
The vet thinks he might have had a pancreatitis episode. This could have been random or from eating a food that upset him. Likely people food on Saturday. We had a party here so he must have eaten a scrap of something in the yard or house. I used to have a relative who didn't believe us when he was a puppy that he was super sensitive to people food and she would sneak him scraps and he would get sick. Since then we have been really super careful, though he would get bits of cheese for meds or a bit of turkey at Thanksgiving. Never hot dogs or chips or plate lickings. I am feeling super guilty for not checking the yard for scraps after feeding 12 under 9. I mean, I should have.
We will recheck his blood and urine in one week. In the meantime we will hand feed him whatever he will eat. Advice and prayers, again, are welcome.
