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.

Perfect treat for my Dolcé!
Pattern Name: Bone, Size: 0.53 Ounce (Pack of 4)
My 14 pound Maltipoo LOVES these. It keeps her occupied for a good 30 minutes. Be sure to get the bone-shaped ones because little dogs will choke on the lollipop-shaped ones.

My dogs love these!
Pattern Name: Ring, Size: 0.42 Ounce (Pack of 10)
I have three very large dogs who absolutely love these treats. They are very picky because they’re very spoiled! But yes, they love these!

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.
