i do an herbal mix that includes rose petals, dried chamomile, oats, and several other herbs/flowes. my chins get a small pinch every night.
personally i love the goji berries. for 1 berry, the sugar content is actually quite low when compared to the content of a raisin. they also have some good benefits as well. that being said.....i only give my chins 1 goji berry maybe twice a week. i alternate between that and a couple other organic items, extra sticks, oat heads, home made hay cookies, etc.... i usually do this when i get home from work and do a head check!
