I stop buying treat for chelsea. She likes pupperoni but now I only gives dog food rolls as her treat. I cut the dog food rolls into small pieces so she can have a lot of treat without making her full. Most of treats in the market contain BHA and other preservatives. Dog food rolls have no preservatives and much cheaper. The $4 dog rolls can last for at least 1 month. She likes it so much and good for training. See below.
