Perfect for small dogs!
Flavor Name: Peanut Butter, Size: 55 Count (Pack of 1)
My toy poodle loves these little sticks. They are small and easy for him to chew, and he loves the peanut butter flavor. The twists are high quality, according to my pup! He gets one a day, and he looks forward to treat time. The snack is perfect for a treat because it does not keep him from eating his food.

Wonderful treat for my Corsos! They also easily break apart if they need just a small goodie 🙂 I've had these on Subscribe & Save for over a year now.

My dogs say these are five stars (and they’re the real bosses here)
Flavor Name: Peanut Butter, Size: 55 Count (Pack of 1), Flavor Name: Peanut Butter, Size: 55 Count (Pack of 1)
I was a little worried these treats might be teeny tiny, but they’re actually the perfect size for my 10 and 13-pound rescue Chihuahuas. They love them so much that if I even touch the bag, they come running like it’s the ice cream truck for dogs. The texture is great — chewy but not too hard — and they keep the pups busy for a little while. I also like that they’re rawhide-free and easy to digest. The peanut butter smell must be amazing to them because they act like it’s the best thing they’ve ever tasted (and honestly, judging by their excitement, maybe it is). I’ve officially learned that I’m not allowed to open this bag unless I’m ready to hand out treats immediately — no exceptions!

Dogs like them
Flavor Name: Peanut Butter, Size: 55 Count (Pack of 1)
My dogs like these, but they're not quite what I expected. They're very thin and oddly flexible. By advertising they were "rawhide free" I assumed they'd be a little longer lasting (like a rawhide replacement). It's not a big deal because they're not expensive, but they don't last long once I give them to my dogs. I don't like the smell much, but I'm pregnant and more smell-sensitive than most now. My husband doesn't seem as bothered by the smell, so they might not be too bad for most people. The smell isn't bad enough that I wouldn't repurchase, but I think I'd probably choose something else since they don't last long and I was looking for something to keep the dogs busy for at least a few minutes.
