These don’t even last 24 hours and my puppy destroyed them. They did not hold up to his teething. I’m very disappointed

Adorable but not holding up well
Color: Green, Pattern Name: Puppy
They’re super cute, have a great variety, but my puppy whose 2 months old and only 9/10 lbs has chewed through the plastic parts already and it’s only been a week or so, they arnt holding up very well for larger breed puppies.

Fun for Pups and You Can Hide a Treat Inside!
These chew toys are fun for my pup! He especially loves that I can hide a treat inside, which keeps him interested and entertained. They’re a nice size for small dogs and puppies, and I also like the light colors because they’re easy to spot when they end up under the sofa because somehow they always do!
