Perfect for a hound puppy
I have a difficult time finding plush toys that won’t immediately fall apart AND doesn’t have any secret squeakers. It’s bigger than I expected, his long hound mouth can barely fit the body inside - and it is very thick that it satiates the bite and catch component. He absolutely loves it, he will bounce it, chase after it and then pass out for a nap once he is done. He knows the toy by name and brings a lot of joy.. Highly recommend.

One of my dog’s favorite toys.
This is one of my dog’s favorite toys. She loves figuring out how to pull the crinkly part out of the rubber tube, and she loves chewing on the spiky rubbery tube. I have to replace this toy often because my dog also likes to pull pieces of rubber off of the tube. She doesn’t ingest the rubber; she just loves the act of pulling it all apart. I am still giving this toy 5 stars because my dog loves this toy and it keeps her busy.

not very sturdy for puppy chewer
The toy was large and it seemed to be made of good material, I was very excited to get this toy for my puppy, but the toy did not even last 24 hours. I was very disappointed. If you buy this product watch your puppy/ dog very carefully so they will not swallow any of the plastic or stuffing

Not good for aggressive chewers
My pup really likes the noises but it took him less than a day to destroy it. (He’s only 8 months old old)
