They aren't cheap, but worth it IMO.
Not sure if you can get them shipped to the US yet or not, you can contact them and ask. Not all places in Canada are going to make them the same way, I can't speak for other brands.
I know Nothing Added has nothing but the highest quality. Drums are cut off, so no grease, no smoke flarouring, no preservatives. Just dehydrated, that's it. The pizzles don't stink either. I have not found one of their products my dog didn't love and that I was unhappy in any way with.
