Pineapple sunshine
Size: 7" XL-Large
Reviewing this after nearly 4 years. I got this for my dog (sadly has passed away), and this was one of her favorite toys. It didn't squeak but the shape and size was what she loved. Big enough she could chomp on in it and I didn't need to worry about her choking. Small enough she could carry it in her mouth when she wanted to play. This is a durable rubber/rubber-like material, I'd compare it to Kong toys, excellent for a dog who loves to chew and needs a toy that can endure their bite.

The only toy my dog has not destroyed.
Size: 7" XL-Large
This is the only toy my dog has not destroyed. He absolutely loves his pineapple, and has figured out a trick to get the treats out. He has destroyed kong toys left and right, the only damage he has done is he chewed the top off. We just soak and wash it, and refill it. It keeps him occupied and is a great treat.

Our Pup Loves It
Size: 7" XL-Large
Our fur baby usually prefers toys that squeak, but she LOVES her pineapple 🍍 toy! It’s the perfect size, its hardness is strong enough for her to chew but soft enough to flex in her jaws , and doesn’t have a bad odor. For the money, it has been a great value with how it can handle her strong chewing and not break apart.
