The Ad got me, the reality didn't
Style: Variety Pack - Large (3-pack)
Directly from the ad- "Exclusive Noisemakers - Each large toy includes 3 high-quality round squeakers to deliver more sound to keep your best friend entertained.". Now my neighbor bought this squirrel with three high-quality squeakers nearly a year ago. It's ragged and tattered I just recently sewed it up for him where he chewed the one leg odd, but those three noise makers are still squeaking. Whe I got my pup, I immediately went to buy one and they were no longer selling them, so I've been on a search for one or an equivalent. These are not. There's no stuffing to get all over the place when your pup breaks into it, a plus. However the squeakers weren't particularly loud and were silenced in a few hours. Two were dead and the remaining one was very well on its way. The toy itself was pretty much intact but that had more to do with the lack of attention from the dog than how rugged the toy is. He'll pick it up once in a while but it certainly didn't meet my expectations. The good thing is that there are three of them so I can give him some brief excitement in the future. Wouldn't buy again.

Strong Chewer Friendly Toy
Style: Variety Pack - Large (3-pack)
My dog is a rough chewer and these last a really long time (clearly since this beaver's face is long gone! The no stuffing is a win too for cleaning up afterwards.

More Durable Than Most
My puppy likes this. He ripped up the stuffing pretty quickly but the rope innards are strong. Both a tug toy and chew. I would prefer it unstuffed so 4 ⭐️ instead of 5.

My dogs favorite toy
Color: Ropiez Dragon
The dragon is pretty durable but I will say my dog chews off the horn the first chance she gets. There is no stuffing except for the horn. Holds up well in a tug of war and play. For an average to moderate aggressive dog it hold up for awhile. It’s not indestructible it will tear.

Very cute toy
I THOUGHT IT WOUKD BE BIGGER. it's about the size of 24 oz water bottle. Kinda small in my opinion. The dogs loved it but I've had it a week and it's already torn apart....my dogs are only about 3 months old so not very strong yet, so I would say it's like mid quality. I'll probably just sew the seam back together and call it good tbh.
