Monkee-doodle loves that it has a crinkle sound when playing tug-of -war
Color: Crinkle Chicken (Yellow), Size: Large
Monkee-doodle likes this toy because it has a squeaker and it also has a crinkle noise maker inside. She loves playing with the toy and it’s easy to spot since it is bright yellow in color. It is suitable for dogs and doesn’t have any pieces that can come loose and harm your pet.

Love it.
Color: Bunny (Beige), Size: Large
Good quality and well worth the price. My dog loves it. The squeaky part is fun, and the crinkly, tear-resistant paper in the ears makes playtime even more exciting.

Good for small breeds and fun!
Color: Multi Squeaker Balls, Size: X-Small, Style: 4-Pack
I’m glad I found these for my 6 month puppies they absolutely love them super fun to play with. Although, the surface has come off due to my puppies biting it off. Look at the sizes as they have a few!

👍🏼
Color: Multi Squeaker Balls, Size: Medium, Style: 4-Pack
This dog squeak ball has been a big hit in my home and keeps my dog entertained for long periods of time. The squeaker really grabs their attention and encourages play, tapping into their natural instincts to chase and fetch.
My dog especially loves how it bounces and squeaks, making it perfect for both indoor and outdoor play. It’s lightweight and easy for them to carry around, even for quick games of fetch in the yard.
In terms of durability, it has held up pretty well so far. The squeaker may not last forever with heavy use, but the ball itself still stays in good shape. Overall, it’s a fun, engaging toy that keeps my dog active and happy.
