I have a bitch with SLO I give her biotin tablet one per day , evening primrose oil and zinc she also has garlic and omega three fish oils ...no flare up for 4 years....she has horrible nails short but probably classed as normal length they dont cause her discomfort and she is stable on this treatment .
(she did loose a nail a few years ago which was when her diagnosis was made ) she has never been on steriods .
I personally think the biotin is the key .
