No angle for correct throwing
Size: 1-pack, Size: 1-pack
This item does not work. It is about ) inches tall. It’s tiny to bend over and pick up the ball. Has no angel for the ball to throw accurately. Ball goes downward. Would not recommend

Cute, fun treat that’s perfect for a dog’s birthday
Flavor Name: Boy, Size: 8 Count (Pack of 1)
This Thoughtfully Pets blue dog birthday cookie is such a fun way to celebrate a pup’s special day. The packaging is adorable and really makes it feel like a treat meant for an occasion, not just an everyday snack. The cookie itself feels well made and sturdy, and my dog was very excited about it. I also liked that it didn’t have an overpowering smell and didn’t crumble everywhere when broken into pieces. It’s a great size for gifting or as a little birthday surprise, and it definitely made the moment feel more special. Overall, it’s a cute, thoughtful treat that’s perfect for celebrating a dog birthday and bringing a little extra joy to the day.
