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.

Favorite treat of all time for our Maltese pup.
Pattern Name: Lollipop, Size: 0.53 Ounce (Pack of 4)
These are my Maltese dog’s favorite treat. I don’t know if it is the whole combination of shape, taster, tendon location, or that they are from a Turkey, but they are an absolute winner when we have them. Since they are quite expensive, we only get them on occasion. If they were less expensive, even by 10%, I would justify regular purchases of them to myself. I highly recommend them for any size, breed, or reason. They are an exceptionally wonderful treat for my pup. I think I have just found the reason for ordering another order of these Turkey Tendon lollipops for my best friend. Especially since he eats them quite quickly, even though he is only four pounds. And they seem to be quite digestible.
