I've never used it as them as they are not available here, but I know a lot of Ontario Toller people have used Tollden patties and seem to like them.
I feed Dance a lot of premade raw. It's convenient, I get a good deal on it, and she does just as well on it as she does raw that I prepare myself. And a few times a week I make sure she gets meals she actually has to work at and chew, but the bulk of her diet right now is premade (meat, bone and organ only). I don't really feed a lot of veggies and tend to stay away from premade that includes a lot of veggies, but lots of people have success and like feeding premade that includes veggies. The Tollden patties don't sound like they're overloaded in veggies either, which is nice. Some are kind of like feeding your dog a salad they're so green.
