Easily destroyed
Color: Green, Pattern Name: Puppy
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.
