I have lost count of the toys I have bought for my boxers over the years but the Kong toys are the only ones they are not able to destroy. They are the toys they go back looking for time after time. They never seem to get bored of them. Excellent for chasing as they bounce around everywhere, and great for stuffing for hours of amusement, although my two are happy to chew them for hours with nothing in them!
Every dog owner should have at least one of these I have the small one for my Yorkie and she loves it, keeps her busy for ages. I stuff mine with dry biscuits and then a soft treat at the top to keep the biscuits in and this does the trick. fantastic!
