Thankyou for your replies, what a stressful weekend :(
The vet saw Candy and her fears were confirmed: She is suffering from laminitis. I believe it was a combination of things: Firstly the Predisolone, which contains Quarterzone to help with healing - but apparently it can cause increased risk of laminitis (which she kindly told me after I had administered 60 predisolone tablets to Candy..) The tablets are usually prescribed to dogs for allergic reactions, and only perhaps 1-2 at a time. Candy was having 25 per dose therefore the medication was very potent.
The Vet stopped treatment immediently, and said that she wasn't too worried about Candy contracting laminitis therefore she didn't feel it nessesary to explain all the risk factors.
IMO, the paddock is FULL of lush green grass, Candy's got the classic 'build' (Stocky, short) of laminitis prone horses.. yet my Vet obviously didn't feel these warning signs were of merit? Candy was beginning to look sore on the Saturday (Vet saw her on Friday) and was certainly having a full blown attack by the Sunday (When the Vet saw her the second time). Therefore I believe it was primarily the medication prescribed to treat the skin condition that caused her laminitis, as well as the combination of lush grass (although she has been in that paddock for atleast 3 weeks).
I have never dealt with laminitis before, apart from the part-time treatment of a pony at the Riding School I used to work at. We have scinced moved Candy into a yard and am feeding her meadow hay. The vet wanted me to lunge her for 10-15min a day, however I have read that there is alot of conflicting ideas as to exercise a laminitic horse, or whether to increase or decrease blood flow to the hoof.
So I have decided to take her for light walks around the barn, rather then working her on the lunge. Thoughts?
One more thing: What exactly is the treatment for laminitis once the horse has been affected? I know the immedient step is to take away the cause of the problem, and perhaps prescribe some sort of pain relief - bute (Which the vet as not done..) but then what happens? How long does the healing process take? I will definately have to get a grazing muzzle for Candy.
The reason I described her symptoms as looking like she couldn't put one foot infront of the other was because I am inexperienced in treating laminitis and at first, to me, it looked almost pyschological. I just didn't realise the pain she was in :( But hopefully my vet can advise a good plan of action.. she mentioned that she could go back into the paddock on Tuesday depending on how she is..?
