What are the best dog treats for training?

Across the reviewers we read, small, soft or freeze-dried single-ingredient treats dominate training recommendations because they can be doled out quickly and broken into tiny pieces. Freeze-dried beef liver (Vital Essentials) and three-ingredient freeze-dried bites (Pupford) draw the strongest specialist-community support on r/puppy101 and r/Dogtraining, while budget shoppers lean on bulk soft treats like Amazon Basics chicken bites.
