Not good news - her test came back positive so we've started on Prasend (sp?). Looks like the vets initial thought was right - the mud fever was only a symptom along with her other itchyness - coupled with the fact that the sores would just not heal and she had begun to get more patches of raw skin further up her legs. So, I am really hoping that the treatment helps her to heal - and that the mite injection is also of some benefit. She is confined to the school all day with a net until her back legs are well enough to wear the mud boots (it says not to use them until all traces have gone). Seems so unfair - I guess at nearly 23 she is bound to have some kind of age related problems - just hope the drugs work and she can go back out with madam before long. I am trying to break her boredom by joining her in the school for long scratches - it seems to cheer her up! Does anybody else know about this drug Prascend and if it has affected appetite? Vet said she may go off her food.
