As Biscuit is on a raw diet I find this a challenge as I want to keep the treats as natural as possible so tend to use good quality kibble, which lasts a while too. To buy a 1kg bag works out so much cheaper than the smaller packs of treats and I just keep a small handful in various coat pockets. I also buy liver treats and will sometimes give small pieces of cheddar or cooked meats such as sausage. He loves carrot, apple, blueberries and other fruits too. You are right though that there is a lot of choice!
