Thank you so much, Marianne, this is very helpful info!

Based on what I've read on this forum, lysodren requires a loading time with ongoing maintenance after. Presumably that is dosed via weight as well? Any recommendations on what that would be if we took the lysodren route? Once again, Lola weighs 22-23 pounds.

My regular vet isn't familiar with lysodren and my dermatology specialist didn't feel too strongly about going with either vetoryl or lysodren - she just recommended that whichever vet I go with should be well-versed in the treatment they prescribe and test often. Reading through an overwhelming (and helpful!) number of threads here, it seems that on the whole, lysodren has been more helpful in clearing up CC than vetoryl for most dogs, so I'm more inclined to go that route.

My regular vet has been wonderful and has gone well out of her way to help diagnose Lola, and while she has been reading up on Cushing's treatment to ensure she is taking the correct route I am feeling like she isn't as well-versed in treating Cushing's as I'd like her to be, so I've found an internal medicine specialist (one who works closely with and is in the same building as the dermatologist) who treats many Cushing's cases and is equally familiar with both vetoryl and lysodren. I was able to get an appointment with him tomorrow, so we'll see exactly what he recommends - I'll report back on that here, stay tuned!
