This toy lasted about ten minutes. First one i purchased had a rope tug, which my pup quickly chewed through, rendering the toy useless. I bought another one after i saw that they had changed the rope portion to a rubberized "rope" and it seemed like a better solution. Wrong! The rubber rope took my dog (who is not much of a chewer) about two minutes to completely chew into small pieces, again leaving her with nothing but a purple plastic jug. Product is a great idea if they can figure out what will work better as the "tug" mechanism, but as is (both versions) are just poorly made and a waste of $$$$.

We have a year old pug who will eat just about anything but these! Unfortunately he just would not go near them no matter how hard we tried to peak his interest.

I first got the variety pack to try all the different flavors, then I picked 2 and ordered them on Subscribe and Save (1 each on alternate months). It's much cheaper than the vending machine at work and they only have chips that are bad for you. These chips are crisp, delicious, and taste salty, mmmmmmm good! Each bag has 230 mg. of sodium. They only have 100 calories in a bag, and the amount of chips in the bag is ample for one serving, unlike other 100 calorie snacks where you get 7 almonds, or 5 crackers.... Now I can have chips every day at work for lunch, no guilt! The Salt and Pepper variety is absolutely delicious. The plain is great for dipping, and the barbecue is full of flavor. The salt and vinegar is very sour, if you like that type, and the cheddar and sour cream and onion varieties are good, just not my favorites. A very good deal on Subscribe and Save, chips delivered to your door, individually bagged and ready to take for lunch. Convenient! Nothing bad to say about PopChips!
