I'm not sure if this is a behaviour thing or a health-related thing or just a quirk, but my Pepper constantly grazes on grass whenever she is outside. She kind of looks like a sheep or a cow just munching away all of the time. I find it kind of strange. Most other dogs I've known, including my other sheltie Honey, only eat grass prior to being sick, but Pepper is very rarely unwell and just seems to really love it. I'm curious if anyone else has any experience with this?
