He's really doing well. He was included in that remark from the vet last month, "I hate that diet. I really hate that diet, but I have to say they have the most gorgeous coats!"
In the end, I decided to find humans that could tell me what having Addison's actually feels like, and I understand why he does some of the things he does when he runs low on prednisone. One of them also helped me understand digestive issues that happen with some with Addisonians.
I finally figured out a protocol for him for when he starts getting indigestion if he runs out of his prednisone for the day, and it really does work. His indigestion is a rare thing except for that now that I've got him off of bone and on calcium supplements. I've actually got him on a tiny bit of bone again, 2# of meat with ground bone to 10# of meat without. He could probably still digest it the old way with the bone if I gave him more prednisone, but I'm not going to do that. Cortisol is REALLY important for digestion.
You really can't tell that there's anything wrong with him anymore once I finally learned when he needs prednisone, or is going to be in a situation that he will need more--like he needs 2.5 mg extra one hour before going to the vet's for his shot if he has an afternoon appointment, and I might as well give him 2.5 as soon as I get home if it's a morning appointment.
Five mg. every morning, and the protocol that works for his digestion if he runs out of that 5 for the day:
If he starts burping before 3 p.m., then give a little food and 1 mg.
If he's still burping by 5 p.m. give 1 mg with supper.
If he's still burping by 9 p.m. give 1 mg with bedtime snack.
If he starts burping before 3 p.m. with smell, then give a little food and 2.5 mg.
If he's still burping with smell by 5 p.m. give 1 mg with supper.
If he's still burping with smell by 9 p.m. give 2 mg with bedtime snack.
Since I've been following that, I've only had to get to that 2mg at bedtime snack twice. Learning all this has been a long time coming though. I have no idea why that low-dose protocol doesn't work for him, but it doesn't, and I just don't care anymore now that I have him back to "normal."
