Indestructible dog toys
Color: Blue
These are indestructible toys. They do, however, hurt if the dog comes and drops it on your head while you’re sleeping. It is also quite scary when the dog drops it on the tile in the middle of the night. Be warned ;)

They are very hard to tear up! Definetly for aggressive chewers!!!
Color: Blue
Dogs love them!!! My 70lb bernese mountain/hound dog mix loves them!!! Taking her long time to chew through them!!! Unlike other chews which would have already been destroyed!!!!
