I am at a complete loss. We started Zoe on Vetsulin back in August. We followed directions and thought we were doing what we should be. Spot checks only at vet's and following her guidance, we did 2 weeks 1 unit 2x daily (no change); 2 weeks 2 units 2x daily (no change); 2 weeks 3 units (showed marked decrease of BG to 200's); very next day Zoe crashed. Emergency vet visit, two night's stay, and slow, slow recovery since. Following that crash on Sept 12th, we've been on and off again w/ injections because of Zoe's intermittent throwing up. Visited internist, ultrasound etc, and diagnosed w/ pancreatitis, possible IBS, dietary sensitivity.... Has been eating Royal Canin PV mostly w/ some Weruva for treats. He doesn't like eating at 12-hour intervals, and with his throwing up, that goes out the window as we try to get him to eat. Yesterday afternoon I gave him 1/2 dose of nausea med. He hasn't thrown up since. We've begun checking Zoe's blood sugar at home now - WHY WEREN'T WE INSTRUCTED ON THIS IN THE BEGINNING?! - and this morning's was 112, which we thought was too low to give him even 1/2 unit of insulin. I fed him about 1/4 can, and we've checked BG twice since, after four hours BG only went up to 233. Anyone have any ideas at all? We feel like our beloved Zoe has become a science experiment.
