Thanks, Lisa. I'll see what my vet has to say. (I love that you always seem to have a holistic recommendation for things!!!) Danny actually likes the Denamarin, it doesn't have any side effects, it's recommended by our vet, and it helped Sunnie many years ago. I know rosemary has been linked to seizures so I've always avoided it to the extent possible...the concern seems to be all over the map but I've always erred on the side of "maybe not a good idea to test". It's already way down on the list of ingredients in the pups' food (and so many foods I've looked at).
