My 2 German shepherds love these good quality last a good bit
Size: Large (Pack of 1)
I buy these for my 2 German shepherds. My male is a heavy chewer and he will spend time with this everyday until he starts to wear it down or makes it into a makeshift shank and I replace it Last about 3-4 months for aggressive chewers. Highly recommend (keeps them from chewing my stuff)
