So in late May/early June one of my pigs started acting really weird. She is normally very active and wheeks when I bring veggies and just gets really excited when I go to the cage. So I started to notice that she was not coming to the cage when I would bring veggies and she would refuse to eat everything except carrots, she had mushy poops and she was loosing weight. So I would see his happen like once a week and then the next day she would be fine and then it started happening more frequently so then i decided to take her to the vet. he said it was probably a bacterial thing so he gave me a gut stimulant t keep her gut moving (since she was barley eating) some critical care, and Baytril. She got better and is acting normal again but ever since this happened her weight fluctuates a lot and i know pigs loose weight when they get older but shes only 2 and a half so i highly doubt that's the problem. before she got sick she was about 1120 grams and when she got sick she got down to about 1000 grams. she started to gain it back again but after like a week of gaining it back she just started fluctuating. she can get as low as 930 grams and she can fluctuate like 50-60 grams in a day. i don't know if I should take her back to the vet because other than this she is acting fine and she has a yearly checkup in 2 months anyway. but I'm just really confused.
With all of the above.
