Good value
Pattern Name: Ring, Size: 0.42 Ounce (Pack of 10)
This is a new treat for our sweet girl and she loves it! She’s a small dog so I break them in two and it’s just enough.

My Shih Tzu goes crazy for these!!!
Pattern Name: Ring, Size: 0.42 Ounce (Pack of 4)
My guy’s favorite treat. He sticks his nose on the bag and can barely wait for me to get it open. Doesn’t upset his digestion. Have ordered multiple times and will continue to do so.

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.
