This can be a hit or miss. Believe it or not, my dachshund can tear through big dog toys, and he's had this one for almost 6 months now and loves it, chewing on it every day. He got to the stitching, but it still holds up well. Ordered another. I recommend this seller. PS - OCCASSIONALY WASH ALL THEIR TOYS!!!

Survived my dog… which almost nothing does!

Size: Medium, Color: Watermelon, Size: Medium, Color: Watermelon

I have a pit mix who is an expert-level destroyer of squeaky toys. Most “durable” toys last her maybe 5–15 minutes before the squeaker is gone. This one lasted a full HOUR of play (constant squeaking, chewing, and trying to find a weak spot) and she still didn’t manage to break it. That’s honestly unheard of for her. What I like: The flat shape makes it hard for her to get a good “kill grip” The squeaker isn’t easy to isolate and destroy It keeps her engaged instead of just ripping it open immediately She actually spent a lot of time just booping it with her nose to make it squeak, which she loves. I ended up putting it away before she could eventually destroy it, and I’ll be rotating it to make it last longer. It’s now a high-value toy in our house. If you have a dog that destroys every squeaky toy in minutes, this is absolutely worth trying. I’m already planning to buy more from this line.

Not for aggressive chewers

Size: Medium, Color: Carrot

This product is pretty strong, but my dog tore it apart in 5 minutes. The size is great, and my dog loved tearing it apart. I wish it lasted longer.
