Not durable- NOT SAFE! Filled with CLEAR PLASTIC WRAP! See Video
Color: 4 PCS Ocean Series
My dogs tore right into these. They didn’t last 10 mins. Inside them, is clear plastic that my dogs were already getting into their mouths. That’s what makes the crinkle noises! CLEAR PLASTIC! This plastic could become an obstruction in your dog’s intestines if they eat that! That’s not safe for dogs and the fact that they are not durable either is a very bad combination! A dog toy manufacturer should know this! If you haven’t bought these, don’t. If you have, do NOT leave your dogs unsupervised with them. Unsafe! They are very cute and my dogs were enjoying playing with them, but they just aren’t durable, nor safe! I’d say they aren’t a very good value either considering what we paid for them. I’m rebuilding mine (taking out the plastic and the little squeakers) to try and make them safer, but I still will be supervising them with them for the short time that they will probably last. Don’t waste your money.
I just purchased these at Christmas- 2024 for my two Scottie Terriers. My dogs just played with these the first time today and it didn’t take 10 mins for them to be tearing pieces of clear plastic out and had it in their mouths. Smh That’s just so wrong. Why would they put that in there? I won’t be buying from this company again.

Great value and fun for dogs!
Color: 4 PCS Ocean Series
These squeaky dog toys are a great buy! The pack comes with a nice variety, and each toy keeps my dog entertained for hours. They are colorful, lightweight, and the squeakers work well without being too loud. The material feels durable so far, even with regular chewing. Perfect for small to medium dogs. Definitely worth the price—would buy again!

Love these toys!
Color: 4 PCS Ocean Series
My 1 year old pup loves these toys. The clam has been a big hit since it crinkles, has a squeaker "pearl" and a rope. He very proudly brings me this to play with him. Recommend!

Stitching can be weakened by continuous aggressive play.
Color: 4 PCS Ocean Series
Not as tough as touted. I will say that my dog loves the textures and sounds. Safely watching so that it does not shred when toy is ripped. Size was perfect for my 80lb dog. Pet has throughly enjoyed an enjoys the toys.

Tough toys for Chewers
Color: 4 PCS Ocean Series
My dogs love these toys, they are tough on toys so these appear to be well made. I don't expect them to stay in one piece but if they can last more than a week, they are perfect. So far, they have lasted three weeks so this is a record for toys. Cute, and funny to watch pups play with them. Squeaks once in awhile and really cool toys.
