Best toy for big dogs
Style: 5 KNOTS
This is the toughest rope I have found. It is the only toy my Rottweiler doesn’t destroy in a day. It lasts over a week with her constantly carrying it around and tearing at it. She loves it.

Great dog toys!
Color: 4 PCS Ocean Series
My 3 dogs simply love them! Exactly as advertised. Arrived promptly. Squeakers in every toy. Well constructed as they are all still in one piece. :)

Labrador
Color: 4 PCS Ocean Series
I have three Labrador retrievers and a bulldog who all loved these toys. They were able to play tug of war without destroying them. This is quite amazing because the bulldog has extremely strong jaws. They play for hours with these toys and they have not become disinterested yet. I would recommend them for dogs who play together with their toys. They are especially enamored of the octopus and the clam. And to my surprise, my old chocolate female Labrador became particularly interested in the salmon. Each toy appears to have multiple squeakers and I think this is what gathers their interest. If you are looking for toys for multiple dogs these should fit the bill!

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!
