i am not to familiar with any of those brands but the most important thing with dachshunds is to make sure that its low in fat because they can become overweight fast and it is hard to fix and can lead to many more medical problems. Another thing to consider is that most dachshunds prefer smaller kibbles the breed is know to have bad teeth.
