Can anyone tell me if my dog is eating pellitory because she's feeling sick OR is the pellitory making her vomit. I've seen her eat this herb twice, once in the garden and once on a walk. On both occasions she's vomiting everything up and has obviously been in discomfort and been off her food. She's fine the next day. So is the herb the culprit or is it something else I've missed. I have pulled up all the pellitory from the garden as a precaution.
