Are these acceptable?

I've been looking into different treats, because who doesn't like spoiling their babies? How does the chin community feel about the following?:

dehydrated celery

broccoli, a rare baby carrot, and tiny pieces of sweet potato (my vet recommended these...)

dried parsley

carob beans

dehydrated leeks

dried bell peppers

dried bay leaves



I've found conflicting info on the vast majority of these on the interwebs, so I figured I would just ask you guys.
