Great assortment at a low price!
Color: Multicolour20
Keeping a puppy engaged in toys can be rough but my puppy LOVES the assortment of toys that were included in this box! She is teething and the durability of the toys have held up well. The rubber materials are soft on her teeth and the rope toys appease her tug of war moments. Would 100% recommend for anyone looking for a good deal on toys.

Don’t leave your dog unsupervised with these!
Color: Multicolour20
Some of the toys I noticed break apart easily. I got these for my 4 month old puppy and they are definitely not chew resistant but he had so much fun playing with them. Some toys squeak. The toys are super cute but I don’t recommend letting your dog play with them without supervising because it can definitely be a choking hazard with how easily he tore them up. He normally doesn’t tear toys up easy so I won’t be buying again but he had fun with it while it lasted. Most toys had to be thrown away within 2-3 weeks.

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!
