Great Toy For a Great Price
Color: Purple
My Aussie loves toys and plays with them as though she is a small child. She has a basket and will go to the basket and dig through it until she finds what she is looking for. Lately she has been using the bungee gecko as her toy of choice. She gets bored easily and will rip the stuffing out of most toys, the fact that this one has lasted 6 weeks or so is impressive with no rips, holes or missing limbs. Her favorite way to play is to come over to me and nudge me to play tug of war and we have broke many toys this way but so far we can play tug a war several minutes at a time and the gecko is still in one piece. For the price which is considerable less than some of her other toys I have already ordered a couple of replacements for the future. This is a great well built dog toy that has has a lot of give and can be stretched without ripping.

No longer as durable
Color: Purple
I have one of these that has made it through 2 dogs but now the bungee is stretched out. It's been such a well loved toy I recently got another one. They've changed the plush fabric. The old one was indestructible. This new one is much thinner and easily torn. I wish they would go back to the old plush fabric.

Great Toy!
Color: Orange
This has been a great toy for our 11 week old German Shepherd. She absolutely loves it. I can get out all of her toys and lay them out with the exception of her "Lizzy" and she will immediately go to her toy bin and get it herself. Needless to say it is her favorite toy. She has had it a week now and she plays with it a lot, chewing and squeaking. It's a pretty amazing toy to have held up this long already and to date shows no sign of wear or damage. Lizzy just keeps going and going.

This item came with plush missingand thread unraveling on one leg
Color: Blue
I bought this toy because my dog spent a week playing with the same toy from Zanies that belonged to a visiting dog. My dog was very gentle with this toy, which he loved, so we decided to find one for him. The toy that arrived had no Zanies label and missing plush on the bottom where the label should have been, plus other bare spots in the area that showed the white mesh beneath. It also had a long thread at the joint of a rear leg so I knotted it at the joint and clipped it to prevent my dog from pulling at it but it's apparent that the sewing is loose and wont last long. The color was also much lighter than the toy he'd been playing with that belonged to the guest dog but I figured it might just be from a different dye lot (it was not bought at Amazon but their local pet store.) I am not convinced this is a real Zanies toy. There were two labels in French and it said it was made in China. I am returning this toy and will get a replacement and see how it looks. If it seems like it will fall apart or is not the real thing I will return it immediately. If it has a label and is in good shape and sewn well at the seams I'll revise this review.

Fantastic Dog Toy!!!
Color: Purple
This is a great toy!!! My dog has lots of toys. But one of the problems is he has trouble getting the squeaker to squeak. He's an 18 lb terrier mix, and those squeakers are just elusive. Breaks my heart. This one, though, the squeakers (there are two) are in small areas (head and tail), that are easy for him to get his whole mouth around and squeak. They also don't move, which also makes them easy to squeak. So he's been squeaking up a storm since he got this! Other plusses: * The material is great (soft, furry material, that seems to be of good quality). * The toy expands and contracts, which is fun. * It's pleasant to look at. All in all, I'd say this is one of the best dog toys I've ever bought for my dog. Highly recommended!
