Finally!
I search constantly for toys without a squeaker and never seem to find one. My curious pup loves ripping them out so I stay away from them. But finally one that he loves but has no interest in tearing apart because it has no squeaker!! Win!

Squeakerless
It is very life like. Held up well but is starting to show some wear after 6 months. I attempting to repair a couple of holes that have shown up. The sqeakerless is nice but would love a noiseless squeaker. I would give 5 stars if I can patch the holes.

Almost 2 years now! Super strong and the puppers loves it. NO SQUEAKER!!!! YAY
Nov 2022 marks 2 years it's now near Oct 2022 unless this thing completely falls apart in the next month it's gonna easily make 2 years. I honestly see this going 3-4 years. There is little damage still. Just a tear near the ear that isn't spreading and the tail is still showing the tiny amount of white. This thing is a beast! Video is from almost Oct 2022. 1 year and 2 months on (last three pics are of it currently) and it's still holding up nearly perfectly. Bought this in Nov of 2020 Jan 2022 it's still around while all other toys are destroyed. This is completely worth every single penny. 6 month update: See pictures for the only damage to the toy so far. Note the tail is the place my girl tends to offer me to grab. She also gnaws on that area and the ears. The one ear has fur missing now. Eyes are still good to go as they are stitched rather than separate plastic eyes. However for 6 months of dog abuse, I'd say the toy is holding up quite well. I feel I'll get close to a year out of it maybe a bit more or less. The pupper girl always destroys her toys. This one has lasted quite a while compared to the others. I don't see this falling apart for a while. I believe we may get a year or more out of it. Well worth the price!

not for aggresive chewers
This premium priced toy did not last 15 minutes with my 14 month old 34 poundf Labradoodle. I had great expectations based on the description but the very cute squirrel toy did not last, First hole was through one of the eyes and the internal stuffing was then spread everywhere.

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.
