Glad to hear she is feeling better, the poor little pet! As this conditions is brought on by an accumulation in the bloodstream of toxic substances that are normally removed by the liver it sounds like your Amber needs a complete detox. Have you considered trying Essiac for her? There is a woman in Melbourne that makes both tincture and capsules for animals so that it is easy to put it in their food or drink. Essiac is a blend of herbs and usually people take it for cancer maintenance or for a complete detox. There are now cases where it is being given to animals for a variety of disease with amazing results. If you want more info about it let me know and I will happily post it on here.
Wishing your Amber a full recovery.
