Sunny is a 27-ish liver chestnut cob gelding. He's pretty much retired now because he suffers very badly from Summer Pasture Associated COPD and something like half his lung function has been lost. He also had one eye removed 7 years ago although that didn't stop him from winning at dressage competitions and being the safest hack for miles around. To watch him normally, you'd swear he was only 15. He has free range privileges at my yard and is loved by everyone. Great character, very food oriented!

2 days ago, my YO observed him laying down on his brisket in the field in torrential rain. All his field mates were sheltering with bums into the hedge. He stayed that way for at least 15 mins and was very slow to respond to the YO calling him to see if he was ok. The next morning (out overnight) he was very very slow to come in, barely able to lift one foot after the other but seemed ok when I got to the yard later. This morning I brought him in and again it was as if each foot weighed 100lb and he barely had the energy to move. He dragged himself into his stable and - so out of character - collapsed into a heap on his deep litter shavings bed. He was in just a no-fill rain sheet and was cold and clammy underneath. Appetite not affected, not colic, not eye problems, not chest problems, not lameness or laminitis. Maybe a little tucked if you looked hard. As often happens, I started remembering odd little out-of-character things that have occurred over the last couple of weeks. It seems as if he simply has no energy whatsoever, almost as if his blood sugar levels drop to crisis level. Long discussion with YO about either wait-and-watch or get the vet out. Sunny is very precious and anyway with the weekend coming up, I didn't want a crisis to develop when everything is more difficult so I called vets. Vet couldn't get out until after 6pm so I put Sunny back out for an hour or two. Unbelievably, by this time he was back to his old self, came marching up the grass bank to see if I had any food for him! Vet has been and his temperature was normal, no obvious anaemia (gums pink and capillary refill fine), chest the same as is normal for Sunny, heart rate normal. They've taken bloods to test for protein, glucose, white cell count, liver function, pregnancy ha ha, you name it.

This has happened on 3 mornings on the trot but he's always fine by the afternoon, although it was tea time ish that he was seen lying down in the torrential rain. Could he be borderline Cushings? Could he just have got very chilled? A virus he's struggling to shake off? Any owners of veterans got any ideas? I don't think this will be the end of it. My money's on some sort of metabolic disorder but god knows what. I'm very worried. Thanks for reading and large serving of Haagen Das Baileys ice cream if you've got this far x
 
Hi I'm afraid i don't know the answer to your question but we did use to have a very old horse on my yard that I helped to look after and he struggled a bit in his last few years (he was a 17.2hh ex national hunt racer who made it to 38 can you believe!) and the vet recommended giving him "Red Cell" to boost his immune system and perk him up, Equine America did start to sell a cheaper version too. If my horse is ever a bit poorly, I put him on it for a week and it really helps him with his energy levels but not in a heating type of way, it is not uncommon for him to look a bit weary at this time of year. I think it is mainly a very strong vitamin/mineral supplement - might be worth a try to see if it helps him. But good luck, golden oldies are so wonderful to be around, I hope he is ok.
 
If there isn't any reason not to I'd bring him in at night. My horse gets like this if she doesn't come in at nights all year!! It's a relatively recent thing (she's 24) and although she is perfectly tolerated by her field mates I wonder if she is a little rejected from the herd and noone will watch over her if she lays down to sleep so she won't but feels safe enough in her stable to lie down. Coming in during the day probably won't encourage sleep unless its a very quiet yard. Also second red cell and global herbs restore has amazing results.
 
My old boy when he was in his early thirties started to have funny episodes where he would just lie down in the field. Would be fine one minute and then didn't want to move. When he did get up he would look at me as if I was mad Each time the vet was called and everything was normal.
 
Thanks everyone. Bloods back and the only thing of note is, staggeringly, raised liver enzymes! I didn't see that one coming! Vets have sent blood to the lab to test bile acids so we should know a little more soon. Also, because of his age and the statistics, they've been again today to take bloods for Cushings testing. He's right as rain again today. Totally weird. Started him on Equivite but if he's got liver problems, I'll have to watch protein levels. A scary time but I'm reassured by Sam100's experience. Interesting too about Redcell but again, if there's liver problems I'll have to take care. And cm2581, yes that could be right about him wanting to be in at night and maybe rejected by field mates. He's got less and less reliant on being in the company of other horses over the last year or so. He has free range privileges most of the day and is quite happy to box himself into his own or any other empty stable and quietly doze there. Yes, it is a quiet yard but all the other horses are out overnight all year and they all thrive on it. But it might be time to bring Sunny in now, except he'd be on his own. I'm not changing anything (except Equivite) until we've got the other blood test results back. Worrying time though x
 
yes best not to change too much right now but bringing him in for a while would also help you keep an eye on him more, is he peeing & pooping enough, how much water he is drinking and how much he is actually sleeping etc. I have a few problems with my stallion right now and we have just taken blood to test for IR and PPID. This is the right time of year for laminitis so I am on the look out. I have brought him in at night and put a video camera in the stable so I can check on him at home. If he is feeling rough he won't bother about being alone and as soon as he is better you could put him back out and as the others have suggested give him some vit/min supplement.
Good luck
 
hope the bloods give you answers and that hes feeling better soon, i know locky who was 35 i use to look after had cushings and i put him on hormonise and that improved his glusoce level and liver and he went from pottery to running around with bea at times,
whats his coat like as poss could be cushings if hes started now shedding properly as that was the start of lockys cushings and drining more too which if you stabled for a night would give you an idea too as if hes sharing a fields its hard to moniter what 1 horse is drinking, he sounds a lovely old boy though
 
Have you checked to see if he has laminitis?, check his pulse behind fetlock. You don't want to start putting loads high protein feeds in him if it is. Ask the vet to check him first I would.
 
I wonder if at his age, he is getting stiff when he gets cold. The temp when we had the pouring rain had dropped quite a bit and it will get cold overnight so he may take the morning to warm up and get the old joints moving. You said he had a just a rain coat on, perhaps he needs a little more tlc and wrapping up now he's aged.
My TBx is 23 now and I keep forgetting he's that old cos he looks really good for his age. I've always tried not to be too soft with him over the early years but now I think he deserves more comfort and pampering.
Hope your blood tests are ok, good luck with your lovely old man.
 
My horse went lethargic in the summer and hasnt been right since. She is now on the mend hopefully. 3 weeks on we took bloods and she too gave us results we werent expecting. She too had high liver enzymes and also high muscle enzymes. They have reduced over 3 more lots of bloods and she is now almost normal parimiters. We also took allergy test from her as she had swollen glands and it showed a few allergens which is causing us hassle at the moment. We think the liver enzymes have been caused by either a reaction to something she is allergic to or that she has eaten something posionious. She still isnt right and had a reaction to something over the weekend so if off colour again.

Hope you get some answers from the rest of bloods. And your is back to normal soon.
 
Thanks everyone. Bloods back and the only thing of note is, staggeringly, raised liver enzymes! I'm not changing anything (except Equivite) until we've got the other blood test results back. Worrying time though x

Sorry to hear about your old horse. I'd put him on milk thistle for the time being if the vet is in agreement. It could be that he has long term ragwort posioning, apparently this can show in the liver even from many, many years previous to you having owned him.

Or it could be that he has a tumour or diseased liver which wouldn't be that uncommon I guess in a horse his age.

Big hugs, hope you get an answer soon x
