Old mare - problem ?

[HorseGirl1]

Hiya , I've noticed strange behaviour in my 22 year old mare lately .
Recently as the weather has been so warm throughout the day I've left her rug off but do rug her by night as it is cold , I've noticed a loss in weight . This thoroughbred mare has always been in good condition even throughout the winter ! This had me a bit worried as she's been on hay and feed throughout all year (I mean she doesn't have a shortage of feed) could this be a dental problem ??
Also in the past week or 2 she isn't eating Her hard feed, which consists of "simply natural feed" and beet pulp . She finishes all her hay and eats and Apple and carrots and grass. She was stabled by night through all the winter but out by day . Since spring has come she's out 24/7 with her 2 friends.

Another thing strange we have noticed with our mare is she'll lay down but within less than 5 minutes she up again . Seems like something must be irratiating her. She has always been a mare to lay down in the field take a nap relax for a lenghthy time so this is unusual for her .
Shes up to date with worming . She's going to the toilet fine and is drinking water .
If anything has a suggestion as to what could be the cause to one or several of these problems please reply 😄
Thank you very much all help approached and no Nasty comments please ☺️

Obviously you know your own mare and observe her closely. I think I'd be calling a vet to give her a check over and perhaps blood test to rule out any problems.

As my mare has got older, I have noticed she does things a bit differently too. However, not eating would have me worrying - food has always been very important to her.

Definatley check teeth, not so sure about the lying down and getting up, but she may be feeling a bit colicky on occasions? Zara lies down and sleeps now more than she used too, but dosn't roll a lot, but that is just my gir.

A full check over by your vet might be the go - our old girls are special and need a bit more TLC I'm finding out.

Echoing what NZJenny says, I'd be a little concerned that she has a bit of a rumbling colic - maybe due to a worm burden possibly?

If she has a dental problem maybe she isn't chewing her food properly due to inflammation of her gums and/or bad teeth and this is why she is losing weight as she is not getting the vitamins/minerals she needs?

I defiantly get a dentally trained vet look at her teeth and give her a general check over .
I should guess she having pain from somewhere pain takes wieght off some TB's so quickly it's alarming .
