Indestructible!!!
My puppy loves these toys and she hasn't chewed through them. That is a major win and shows how durable they are.

Not durable at all.
Not durable. My cocker spaniel puppy shredded the ropes in no time. They're cute, and for that I'd give a star, but cute does not support the point of having it. Would not recommend and would not buy again.

For Small Dogs
Wish it was longer. It would be good for very small dogs. I think medium dogs or larger need a longer toy.

My dog's favorite toy* (*see durability warnings*)
Style: Variety Pack - Large (3-pack)
This is a plush toy, so *if your dog is a destroyer of things, it'll destroy this toy easily/instantly* & if they're not destroyed right away, I'd definitely expect them to be destroyed eventually just given the type of toy it is- plus much of that depends on the way your dog plays. That said, this plush, multiple squeaker toy has held up really well for the amount of use it gets in our home. Because it contains 3 separate squeakers in it, these toys have been like heaven for my 3 year old, male, Toy Fox Terrier to play with- he freaks out when we squeeze more than 1 squeaker at the same time & I don't do all 3 at once bc I think his head might actually explode LoL 😋! Seriously, ever since he's grown out of puppy-hood, he's much less destructive with his toys now, so we are able to buy toys like these for him, have him go nuts freaking out on them & have them hold up pretty well/for a while before it's time for a replacement, yet since they're not very expensive, it's not terribly hard to replace them if needed (he's still using the last toy in the original 3 pack we got for him). It's great for fetching via a "flinging" motion (they're not heavy enough to actually throw) if you have a smaller dog who doesn't cover much distance too readily, but the best part of this toy is the elongated design of it, because it makes for a perfect "tug of war" type of playtime toy with my little buddy (tugging is a behavior which you may or may not want to encourage your dog to do depending on its disposition). Since my dog thankfully isn't really destructive & doesn't have issues releasing a toy from a tugging interaction anymore, these items have held up pretty well for a plush type toy, but again, if you own a dog known for destroying their toys, or anything else for that matter, these probably aren't going to work out well for you. Given they're pretty cheap to replace, for a throw ready, tug toy which has 3 different places for a dog to chomp on to make it squeak, they've turned out to be perfect for our smaller sized pup & have become a favorite toy of my little guy which he's always ready to play with, at any time, with anyone- he's got it ready to go a lot of the time when we get back home to him after being out. Again, you'll need to go with Kong or something similarly durable if your dog destroys things or is still a puppy who doesn't know better, but for an average amount of wear & tear they've held up really well while remaining at the top of my dog's favorite toy list. So recommended for sure, but just know if you've got a chewy character on your hands, despite all the fun they'd have with these, I'd get a more durable toy instead of this one as these plush toys, while good quality, will not hold up to prolonged abuse (as is the case with most plush toys sold). However, for an "average destruction" level dog, it seems well enough made to last a decent amount of time & they're a source of an enjoyable playtime for our dog & therefore for us as his owners as well! Definitely recommend for it's features, like 3 different squeakers, it's great design for a tugging style of play & it's overall good durability for a plush style toy. 👍
