Captain Beauregard T
Size: 1 Pound (Pack of 1)
Chik'n Chips are our dog's favorite snack! Beau is absolutely crazy about them.
If you really want him to do something, just tell him to "Sit" and give him a
Chik'n Chip. Or show him one and ask him "What do you do?".

The dogs love it!
Size: 1 Pound (Pack of 1)
