Re: Lameness - arthritis or laminitis?
I know you're what I would term an 'experienced' laminitic owner, so perhaps I'm teaching my grandmother to suck eggs !!
From my experience of laminitis and Cushings, they stick the front legs out to load their weight on their heels, as the toes are painful, which doesn't sound like your girl is doing.
Also if she's not moving much over night and so is stiff in the morning, that would perhaps indicate arthritis more than anything, as they tend to stiffen up easily if they don't keep moving.
Would it be possible to let her have 24/7 turnout, but limited to the yard, or on a small patch of ground with access to shelter so she can move around all the time?
And 2 danilon a day is quite a high dose for her to still be showing discomfort......
Hope this has helped, and that you can sort out what the problem is.
