We have her on 1 scoop of Thyro L per day, which doesn't seem like much, but that's what the vet recommended, so there it is. Since she's started the Thyro L, she obviously hasn't lost any noticeable weight in 2 weeks, but her crest is sagging to the side of her mane now. It reminds me of the Killer Whales in captivity that have their dorsal fins to one side. Is this normal? It doesn't seem to bother her, but it does look rather odd. Just wondering if anyone else's horse had the same reaction to Thyro L.
