Necessary for a small dog.
These are great for a small dog! They can get their mouth around it unlike a round ball. My dog is obsessed with these. They are great for making him love a new guest to the house. All they have to do is squeak and throw the toy and they have a new friend!

Great for little dogs but squeaker breaks too easily
My Maltese is about 4.5 pounds and absolutely loves these! He got very excited to play with it right away. The shape is like a slightly flattened ball which is great bc he can pick it up in his tiny mouth. It’s actually quite cute to see him run with it back to me. When you throw it, the way it bounces and rolls is very unpredictable, which I think adds to the fun. Sometimes my pup drops it while running back and it goes rolling or awkwardly bouncing away from him which causes him to get more excited to chase it and grab it again. It’s been a highly entertaining toy for almost a week straight. The only downside is that the squeaker in it isn’t very durable. After a few days of playing and chewing to squeak it himself, the squeaker barely makes any noise. My pup isn’t an aggressive chewer at all so if your dog is an aggressive chewer, the squeaker really will not last.

G for small dogs
My Havanese absolutely loves these small toys, which we refer to as pucks. They are the perfect size for him. His previous favorite was a small green pig, but ever since we purchased these for his second birthday, he has shown no interest in the pig. They are easy to throw and fit comfortably in his mouth. I plan to purchase more. I would not recommend for strong chewers. My only complaint is I wish they all had happy or crazy faces instead of angry or sad ones.

my dogs really loved this toy. I would highly recommend this, but the squeaker is louder than normal so if noise bothers you, then I would not recommend.
