I have a 92 lb Chesapeak and a 65 LB lab, they can't get enough of this thing. It has lasted about 2 years with some life left in it still. The girls play with it almost daily, they tug, shake and chew on it (both are under 3 years ols so this has been through puppy teeth) and it doesn't fall apart. They pull each other and play tug with us and it doesn't break. It is flexible enough for them to grab easily plus the large holes are great for us to grab as well. My girls chew through most other toys in 24 hrs, but this ball is having a 2nd birthday. Money well spent!
