constipated, not eating old pot belly pig

Question
Our 16 Year Old pot belly pig is not eating her pig chow or anything but fresh veggies (mostly carrots)and won't drink unless we put cranberry juice in her water.  I gave her a lot of prunes yesterday and today.  She peed and pooped a lot but the poops were quite hard.  She spends the day in our back yard where there are a lot of acorns that she likes to eat.  Could this be part of the problem?

Answer
I would take her to a vet if she is not normal soon.
What we worry about is an intestinal blockage.
The acorns could play a role.
We would give her a third of a can of pumpkin to loosen her up.
But any time a pig's appetite changes, it spells possible trouble.
You have taken great care of her in order to be 16!
Good luck,
Pris
