Go dog toys are the best!
Size: Large, Color: Dinos Frills (Pink)
These are the only stuffed toys I buy for my Pittie because they are so well made. Even when she unstuffs them, she plays with them forever!

My dog loves these toys.
Size: Mini, Color: Gator (Pink)
Not a huge toy, nor is my dog. But we have lots of goDog toys. Practically indestructible and my dog likes to carry these in his mouth and bring them onto the foot of our bed. Brilliant colors and good squeaker but my dog is afraid of the squeak. Fair value for cost.

Our XL dogs love them. Highly recommend it!
Size: Mini, Color: Gator (Pink)
Our XL dogs love this! Highly recommend them! Highly recommend. Not for aggressive chewers but our big dogs don't destroy their toys. They cherish them. Great for play and cuddling. Not to loud either. Very cute.

When they said strong...
...they weren't kidding. Our pup would chew through everything she could get her sharks teeth into. Like my arms. Nothing lasted as long as a week or maybe two. But she has had Dino for months now. She loves him. He is the go to toy for when she wants to play tug. The material used to make this toy is every bit as strong as the seller claims. I will definitely buy from them again. And I will not wait for this one to rip. I may be waiting a long time. If your pup likes to tear stuff apart, feel safe in buying this toy,
UPDATE: 2/9/2023
Dino finally succumbed to the torture. His back ripped open and despite trying to repair him with ordinary thread he couldn't withstand the pressure, His stuffing was removed and spread all over the living room. Completely emptied he is still a good toy. Strong enough to withstand the forceful play of tug-o-war.
Only thing I would suggest is to use something stronger when closing his back. The rest of him is great. I will be replacing him soon.

Not so tough
Size: Mini, Color: Gator (Pink)
I bought this because I dog sit. The dog chews up every. Single. Toy. So I bought it since it was cheap and it can be in the “chunk” (the dog’s name) toy box. It is not durable at all. He tore it up just as fast as a cheaply made toy.
Chunk LOVES it! He would not stop playing with it. He loves the squeakers, it is a perfect size for him to throw it up in the air and chase it, and he loved ripping the legs off. It is good for my husband and I because there is little to no fluff.
However, it is the perfect size to drop behind the couch and not be able to get. So once he drops it behind the couch, he won’t get it until morning.
Now for my dog’s rating. My dog loves this toy too. He is much more gentle with toys (he has $5 Walmart toys we bought him back in 2020 in perfect condition that he plays with them every day). Before Chunk came over for the weekend, my dog Ted played with this. Ted is a larger small dog and chunk is a smaller small dog. And it is still the perfect size for both dogs.
