Bully breed has not destroyed the toy yet
Pattern Name: Apple, Size: Large
Ordered this toy for my Doberman and beagle who destroy every toy they are ever given. The green rope on top of the apple toy lasted for about 24 hours, and the squeaker inside the toy lasted for about 3 days. But the overall body of the toy is still in tact and it has been over a month now. The dogs still play with it despite the squeaker not working. The body of the toy is definitely durable if you have a bully breed. Both my dogs really enjoy it. Edit: 7 months later and this thing is still going strong. My doby loves it. It is tough as nails. Changed review to 5 stars.

love love loved it
I am now 55 years old and i love shinny stuff, so i decided I wanted glitter for my hair. I found this and am in love. It is very fine glitter and it just goes on my hair every so subtly. It catches the sun just right and i sparkle just like my personality. Not too much too look crazy just enough to look nice. Looks good on the arms and legs too for a night of dancing.
