Great selection of dog toys at a good price!
Color: 25 Pack (Value-Toys)
Lots of great toys for your little little dog at a reasonable price. Even comes with doggie poop bags. At any of my local dog shops just one of the ropes would cost me the same as the whole box of toys.

Excellent Variety Pack - Dogs Love These Toys
Color: 25 Pack (Value-Toys)
This 25-pack is fantastic value with excellent variety—ropes, squeakers, and different textures keep dogs entertained. They're colorful, well-made, and my dogs love them. The main downside is the chew resistance on the rubber toys isn't the best; aggressive chewers can break through them fairly quickly. That said, for the price and the sheer number of toys you get, it's still a solid buy. Perfect for rotation and keeping dogs mentally stimulated. Just know that heavy chewers might go through the rubber ones faster than expected.

Fantastic variety of doggie toys perfect for our little fur baby!!!
Color: 25 Pack (Value-Toys)
Fantastic for smaller dogs, our little chi-mix loves all of the toys, there's such a great variety and he's having so much fun chewing them and playing fetch with them. Even comes with many extra rolls of waste bags which is awesome. Highly recommended for the value and amount you receive!

SMALL DOGS ONLY!!!!
Color: 25 Pack (Value-Toys)
Every one of these toys are made for very small dogs. 🤣 They're almost too small for my 8 wk old border collies. Im still not upset at the order though as the pups will all be rehomed after this weekend. Was just bummed that every single one was made for SMALL DOGS. Am super happy with how fast shipping was.
