Worth it
Style: Charming Squeaky Dog Toys
My dog loved every single toy. He got so excited with how many they were that he didn’t know which one to play with lol. Great price for many toys and good quality and material.

My dogs love these toys!
Style: Charming Squeaky Dog Toys
My dogs (14 lb pug and a lab) love these toys! I give a couple to them here and there so the box lasts longer. The squeaker does go kind of fast and that’s a lot of the draw but it was a great price for all those cute little toys. They even threw in a few rolls of doggie waste bags. Great value! Will buy again.

Great quality- small squeakers
Style: Charming Squeaky Dog Toys
They are fine but they could be better. They are super cute- lots of cute shapes. All are about the size of an adult fist. The squeaker in each on is roughly the size of a nickel. I guess I had envisioned a bigger squeaker so more of the toy squeaked. They are fine though. They seem well made, no tags sticking out or loose threads. My dog has killed the squeaker on 4 so far today, but that’s the point and the reason I bought them. Oh and they don’t smell weird!! I have bought some that smell like they’ve been in the cellar for years- these do not. So honestly my only complaint- and it’s just personal preference- is I wish the squeaker was larger.

Good for small dogs
Style: Charming Squeaky Dog Toys
My dog (20lb chihuahua-pug mix) adores these. She's a plush toy serial killer, so the toys don't last long in my house, but with their pricing they are an affordable choice for being sacrificed. If your dog is more gentle, I can forsee these toys holding up very well for long term play and cuddling.
