All of those are what I use.
The only extras are cookies that I purchase from members here.
I use two different cookies, one is oat based that I get from stacey wolf and 75% of my chins like them.
and the other is hay based and ALL my chins love them and they are from Essentia.
both cookies are broken up into smaller pieces as I would rather give them a small treat every day.
I do use herbs daily with my chins. all are organic and i make my own mix. thier favorites: peppermint, red clover, dandelion, rasberry leaf, hibiscus flowers, bee pollen & pink rose petals. given in extreme moderation, about 1/3 - 1/2 teaspoon total of the mix, which includes other things, so they really only get a small amount. you need to be very careful with herbs.
