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.

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!
