Not for small animals
I bought these for my ferret and even though it’s hard for her to pick up, they’re so cute and soft.

Squeaker Shenanigans!
I have four large dogs - 65-70 lbs, pittie babies. Three out of four love, love, LOVE squeaker toys. You can't keep a squeaker toy in my house to save your life. If it squeaks, it dies a quick squeaker death. We generally buy squeak toys at the Dollar Store. My going theory on toys is it has to last one minute per dollar I spend on it. Then I call it "worth the money." Right now, it is winter and where I live, so very cold. My kids can't get all their energy out by being outside, so we have to come up with creative indoor fun. I like these types of packs of toys, one for the value and two the quantity. I put all the toys in a box, and then my kids get to come up and pick one out of the box - they then run off for the squeaker toy of destruction fun! Squeak! Squeak! Squeak! Death. One kids goes right to hunting for where the squeaker is inside the toy, and the hunkers down to figure out how to get it out and kill it. She is usually the 60 seconds or less, 1st Place Squeaker Death Winner. The other two, will take their time and enjoy the squeaks and work the squeaker out until death finally takes it. My 70 lb boy, is kind of a baby, and after he neatly gets his squeaker out, he makes the toy his baby, and then carries it around proudly. Considering how large my kids are, these are well made and take the full minute for Squeaker of Death girl to get the squeaker out. The size is great, even for my larger dogs. I got nine toys for about $12 at the time of this purchase, and it was perfect. It did come with the storage bag...but not something that is necessary in this house. Although, it was actually quite nice, and I am sure I can use for something else. The Sun was a big hit, and despite not having its squeaker anymore, is still hanging around, days later. I will be buying this pack again.

Pom approved!
My pomeranian ONLY plays with small stuffies that squeak. She loves these and they are just small enough for her to hold and squeak. They are durable enough - but we will see when her big dog cousins come play with her, just how sturdy they are! They are very cute, soft, and squeak well. Good value for the pack of them.

He loves his new toy and it’s funny!
Ever since I got this toy he can’t seem to stop holding one! Every time I look at him he always is has one in his mouth no matter the time of day. As you can see in my pics he is super proud and happy to go for a stress reliever after a hard day of being a dog. It’s honestly very entertaining and funny to watch and never fails to make me laugh. This item is super durable, and squeaks as he chews on it! It’s worth every penny if you ask me, perfect size and like I said super entertaining and looks super funny! It’s nice and soft so it won’t cause any damage on teeth would give this toy 10/10!

We are still laughing! Great toy
Fun, Interactive, and Great Quality Dog Toy We purchased this dog toy and it has been an absolute hit in our home 🐶😄. As soon as we opened it, our dog was immediately interested. The main toy opens up and includes three individual “cigarettes” inside, which keeps the playtime going and makes it much more engaging. We’ve had so much fun taking photos and videos because he carries it everywhere: 🛏️ to his dog bed 🛋️ to the living room while we watch TV 🛌 to the bedroom to stay close to us The quality is excellent: ✔️ Durable, well-made materials ✔️ Strong stitching ✔️ Bright, attractive colors ✔️ Perfect size for carrying and playing This toy is not only interactive but also very original compared to typical dog toys. You can tell it’s designed to stimulate curiosity and keep dogs entertained. We are very happy with this purchase and would definitely buy from NestPark again. Highly recommended if you’re looking for a fun, unique, and durable toy your dog will truly enjoy 🐾💛.
