Hello. One of my piggies has lost about half her body weight over the past 3 weeks, she has also lost all the hair under her chin. At the same time, she has started begging for food every time I go in the living room and she is definitely eating plenty. The vet has examined her teeth - they’re fine; no lumps and bumps; he’s also given her an x-ray which has shown nothing. He is lost as to what’s wrong with her, as am I. She’s happy enough and eating but she looks so dreadful, poor wee toot. I wanted to ask if anyone here has come across anything similar before and also, should I try to hand feed her too to increase her weight?
