This am he refused his meds and any food and was very lethargic. I called the vet and went straight to ER. Hans was extremely dehydrated with low body heat. They put him on fluids, gave pain meds and warming blanket. Hours later we got word from vet that Hans is doing better. Syringe feeding. They think there's an abnormality with his jaw and possible scurvy even though we've been giving a good veggie diet.
I'm happy he's doing better. Got vitamin C supplements for Chewie who seems to be looking for his roommate.
I'm glad I called the vet today and wishes I had kept to Fridays app. Fingers crossed he continues down a positive path and returns home.
When in doubt, call the vet!
