Honestly, I think my piggie had the lack of a good diet along with some stress. I 'rescued' her from a
pet store...she was their breeder's pig.
She was very skinny and loaded with lice. I think it took her system awhile to adjust, once starting a healthy diet and getting used to a new home.
First she had runny poops (had to clean her feet with an old toothbrush...yuck!) then we went in the opposite direction with a bowel obstruction! The vet treated her with Prilosec and Reglan.
Her teeth even went through a stage when they kept breaking, but now they're healthy and strong!
Sorry to go on...I do hope Olivia 'straightens' out!
