Unbelievable Value: Durable and Adorable! My Pup Loved Then Instantly!
Color: Multicolour20
My brand new pup LOVED THESE INSTANTLY! I He’s 10 months old and still in that “gotta chew on everything “ stage: those puppy baby teeth can really get itchy. I love that these toys nontoxic but they are definitely tough. When I opened the box I wasn’t overwhelmed with the small of chemicals. It’s a similar, clean feeling quality as something I would have purchased for my son back in the day. The variety of shapes and sizes is perfect. All the little nubs on the silicones are also in various sizes from larger to fine and really help him get those tough hard to reach slots. I would definitely give them an A+ on appeal and durability. My GSD played with one for 30’ minutes and it was still in tact. He can rip pretty much anything to shreds in under 5 minutes…I’d call this purchase a win-win. Can’t beat the value for the money. Material is quality. They’re cute and adorable. Can’t beat it!

This package is suited for puppies and it is priced right. 20 toys for 20 dollars and my little guy loves them. No outlet pet store will sell you this amount for the price. Great buy.

Color: Multicolour20
My puppy loves to pull the toys out of this box and he especially loves the rope he likes to chew on it and I just really like that there are different kinds of toys for him so he doesn't get bored. The rope only lasted a couple of months. He chewed the heck out of it.
