Feeling v low,have had my new boy on trial for a bit and he hasn't been the most liveliest boy since i got him but as he is a sort of plod anyway i assumed it was him being a little foot sore,he started teetering a bit on rough ground so i got permission from his owner to get him shod as we are quite flinty up this way. Anyway last week i rode him out and he stumbled badly on a hack. I put him out for a couple of days as he seemed fine in the field on grass so assumed his feet were playing him up,sunday\monday his near hind looked stiff and he was a little unlevel so booked a vet appt for this a.m as was not happy with him,went to get him in for vet and saddler (wanted to check saddle wasnt anything to do with it) and when i got to the field i got 3 horses ready to go but he wouldnt move forward and when he did he really stumbled and was v unbalanced,in the end i let him go and he followed the other horses making his own way to the yard. Vet came and after various tests and trot ups etc he thinks its Ataxia (wobblers). I feel so awful as if its my fault, i had rang the owner last week to say he wasnt right on his feet and was throwing his head around when going down hill (they get worse when up and down hills) and she said 'oh well you knew he headshaked when you took him on' i said i wasnt worried with the headshaking but i know it not headshaking,my other horse is a severe headshaker and she doesnt do it at this time of year. So we left it that i would get shoes put on him and saddle checked and go from there. I left a voicemail on her phone after vet came but will try and ring in a min again to tell her whats happened today. The vet thinks because i have started working him it has surfaced,he said he would of had it before i took him on but and back then he sat in a field for 3 yrs rotting. I have formed a really strong bond with this horse and he is sweet in everyway,only just 5. I am getting my friend out on saturday who is a equine vet for a 2nd opinion as the man who came today isnt my normal vet. He thought he could have an infection in the spinal cord or a locked stifle or even a pelvis problem so at the moment its vague but he thought without doing v expensive things its more likely to be wobblers. I feel so down and i know the owner wont want to carry out further tests and my ins company wont cover him as i have had the cover out only a short while with them so his future looks bleak. I have put down a deposit on him but not paid the full amount yet, i know i need to send him back to the owner but it doesnt take away the hurt.
