Obstructed bowel or stomach virus????

I would ask your vet if you can get it in a pill form. Personally I find liquids much harder to give, especially when they are as nasty tasting as metronidozole! Yuck!
Also, someone posted recently on a product called "pill pockets" (I think) that they got at Petco. It's a treat you put the pill in and they said it was really helpful for them. Maybe worth checking out?
