Pattern Name: Lollipop, Size: 0.53 Ounce (Pack of 4)
Need to make sure you are supervising your dog. With in minutes my small terrier had the stick end down her throat with the whole ring end in her mouth. Had to hold the stick end and let her chew on the ring end. Lasted about 20 minutes.

Natural healthy dog treats.
Size: 3.8 Ounce (Pack of 1), Style: Sweet Potato, Ring
Our dog loves these treats. They're also not filled with the junk like in other treats. These are one maybe 2 ingredients only. Better for our pup.
