Water consumption - too much?

Firstly apologies for multiple forum postings - the posts seem to disappear so quickly I'm never sure where is best to post and I don't know whether I'm being overly neurotic or whether I'm right to be concerned and in thinking dropping a line to the vet tomorrow is required!

Basically my mare (approx 520kg, 16.1hh, tbxid) seems to be drinking a lot at night....

She has started coming in at night for about the last week and whereas normally 1 large tub-trug of water (I'd guess approx 20L) would see her through the night she has been draining it dry. When checked around 2 1/2 hours after coming in it transpired she'd drunk half!!

So last night I gave her a second bucket and I'd say in total she drank approx 30-35L between 8pm last night and 9am this morning. She clearly didn't drink it all as although neither bucket was tipped she'd obviously done her trick of filling her mouth up, standing in her doorway, and "chewing" resulting in most of it falling out as the floor behind and infront of her door had a lovely puddle!

The only major change is that she's started coming in and this winters hay is absolutely gorgeous - very green, very dry, very soft and she loves it so wolfs it down (think half a bale small in 4-5 hours!) whereas normally she'd pace herself throughout the night.

She looks (and feels) well in herself, her coat is gorgeous, glossy and soft. No thick/wooley cushings type coat so I'm thinking that is unlikely?? She isn't looking uncomfortable at all or like she needs to pee, nor have I noticed her peeing excessively though her bed has been slightly wetter (which I'd expect if her water consumption has gone up by 50%!).

The only thing I'm not sure of is how much she's drinking in the field. It definately doesn't seem to be as much as in the stable. She shares her field with one other horse and between them I'd say they drink approx 20L while out (9am-5/7pm). When they were out 24/7 they'd drink approx 50-60L between them in a 24hr period. Water in the field is clean.

So ideas?? Am I being paranoid? Should I give it a week and monitor carefully given she is well in herself? Or should I ring the vet tomorrow and see what he thinks? (having a GP in the family I appreciate how irritating minor concerns are and don't want to end up wasting the vets time over something which may be completely trivial!)
 
My horse is like this occasionally, I wouldn't worry about it :) We can get super thirsty too from time to time!
She might not be drinking in the day so feels thirsty when she's in.
Unless you are worried about her health (and to me she sounds in lovely condition) I wouldn't worry! I would probably enquire as to why too. Is there something she's eating ? Maybe she has a lot of salt intake.
 
I would guess that it is because of her increased hay consumption. Does she have to be in a night? Could you put her back out for a few days to test this out? TBH if she's otherwise completely well, I doubt if the vet can suggest anything other than monitoring for a few days.
Good luck!
 
niagaraduval: She doesn't really have much of a salt intake, other than what's in her feed. They do have a lick in the field but it has sat there totally ignored for 6 months so I doubt that is the culprit. Nice to know she'd not the only one who drinks a lot.

She could stay out but I doubt it would be constructive as she would most likely pace like a loony and stress out all night as she doesn't like being on her own for any length of time (more than a few hours) and her field mate has to come in due to his weight. I'm erring towards the hay being the culprit - the irony is its the nicest, least dusty hay we've had in ages!
 
Though it is nice hay and not dusty, it is still a very dry thing to eat! You could try soaking the hay to see if she drinks less when the hay is dampened, but I wouldn't be too concerned if she appears fine in every other way.....
 
I agree with the others, she's probably eating so much she gets very thirsty as hay although very palatable is dry and if she is stuffing herself she will need more water. try soaking it and see if that reduces her water intake. One of mine will actually dunk his hay in his water bucket to counteract the dryness I suppose.
 
Unfortunately she point blank refuses to eat soaked hay, fussy madam! I could get some hayledge (which she loves) and try mixing that half and half with the hay so the combined water content is higher, but I had hoped we wouldn't be feeding hayledge for another few months....
