The joy my dog gets from these toys is priceless!
I have a 5 year old Rottweiler, Poppy, who will absolutely annihilate any toy within minutes. I’ve had them all… same outcome. Stuffing all over within seconds and the enjoyment is short lived.
I love these toys. There are several squeakers in them so once she gets ones out, she still loves the toy because she can find another squeaker. Also, because it’s long (yet substantially sized) she LOVES throwing them around and whipping them back and forth - something she does even after all the squeakers are gone. That alone makes this toy worth it. She typically no longer plays with toys once the squeaker or stuffing are removed but she will continue to whip these snake toys around and they’re durable. I don’t have to worry about her eating small pieces of cloth that is ripping off the toy.
Having said all of that…. I’ve ordered her a few over the last several months and found that these toys are her favorite above all else. I’ve also found them to be a good value for me.
But… if I could give these toys 25 stars, I would. My Poppy girl was recently diagnosed with hemangiosarcoma and will have about 6 more precious weeks with us, if we’re lucky. So, I ordered her two more. Because, she can have all the toys, right? And the pure amount of joy that lights up her beautiful face every-time she gets a new snake is priceless. I will absolutely continue to order them to make her remaining weeks as delightful as possible.
I will be forever grateful for the happiness these specific snake toys bring my baby girl and could not recommend them enough.

Not so great for aggressive chewers!!
EDIT: well it’s been two days. My boy (American Staffordshire Terrier) has broken one of the squeakers and has made a
Hole. Even tho he LOVES this toy and has been carrying it around the house it’s not for aggressive chewers. It’s pretty tough.. tougher than most but not Black Kong Tough. (Wykyk)

My little buddy loves it! (Loves it no more)
I ordered this in advance of the arrival of my 11 wk old Corgi pup. Not knowing what kind of a chewer I was getting, I wanted something that squeaked but did not have too many extremities to rip and tear at. I also didn't want too much stuffing to end up all over my house and in my buddy's tummy. It is soft and well constructed. I like that the snake is compartmentalized so that if one segment is breached, the others are not.
As it turned out, at this time, my pup is not a violent ripper (except for with paper and cardboard). After a week of testing, it is his favorite toy. It took him about two days to figure out how to squeak it and boy does he love it. It is the only toy he will haul around, which is hilarious because its bigger than he is. It is also the only toy that he will play fetch with. I'm also working on "leave it" with the with him.
Nemo chews a lot, but hasn't shown much interest in ripping at his toys, so after a week (if it were washed) it could probably pass as new. I also try to switch him over to a bone or rubber toy when he starts getting really excited. I am weary since my last dog was a lab who would shred her toys in seconds.
Nemo was ripping at the tag (something about paper) so I cut that off to prevent a seem getting opened up. I'm surprised that the tongue is still intact. The tongue and eyes are weak links and Nemo does like to chew on them.
Overall, I'm very pleased with this toy. My husband was skeptical and thought it a bit ridiculous, but even he has decided it was a good buy.
*Update*
Our original snake lasted 7 months. Nemo loved it. He would carry it around with him and squeak it till my husband and I went insane. He had mastered the rapid fire squeak. It was also the only toy he would reliably fetch. After 7 months my pup had punctured two of the squeakers and the fur was getting threadbare in some place. But overall we were very happy with the product.
Last week we had a guest GSP at our home and he demolished the toy within minutes. Shredded all of the squeakers and the casing. So we were forced to get Nemo a new one. Unfortunately they have since changed the design. There is now a piping that goes all the way around the snake (before it was blind stitched). Nemo has a thing about tags and edges, he works slowly and methodically to nibble them off. Once the piping was compromised, Nemo had easy access to the squeakers. This new version of the toy lasted only a few hours. I am extremely disappointed with the changes made. I have reduced my 5 star review to 1 star and will no longer recommend this product.

These really are durable and tough!
OMG! I have 2 large dogs. A 90 lb.golden retriever and a 75 lb. black lab mix. They LOVE to chew and every squeaky toy I have bought for them is demolished in less than 2-3 days! Even the KONG brand. I have spend hundreds of dollars on various dog toys, chews, squeaky toys, etc.None of them stood a chance! LOL
So, I saw these "stuffingless durable tough" snakes and decided to give it a try! Why not?
My husband even told me NOT to buy them as they would just be torn apart in days.
The snakes came and each dog got one. I ordered 2 of the same color in red. At first, they weren't quite sure what to do with them
as they are pretty long. Approximately 2 feet. They slowly began to trust that this was indeed a "toy" and began chewing on them and our golden retriever was tossing the snake up in the air and biting down on it as it fell to the ground. I also like the fact that the squeakers are a low volume and not so high pitched squeak!
Well, long story short, they have now had the snakes for 6 days and they are still intact and the dogs absolutely love them!!!!
I am so happy I finally found a dog toy that my dogs don't destroy!!! I will definitely be buying more!!
