Penny mentioned gas meds for piggys. I use Infants Gas Relief anti gas drops. It contains simethicone 20mg in 0.3ml. I give 3.0ml at a time and repeat in 2-4 hours as needed. Simethicone is not absorbed so you can not overdose your piggy with it. I am not a vet. Cheers, Ann and the Rescued Piggys of Piggyville, Tampa Florida USA.
