If you need gluten free, non-dairy and no egg, pickings are pretty slim.  If you use a really sharp serrated knife and work carefully, you can split them successfully.  Great for mini-pizzas!

I have a 2 1/2 year old 60 pound German wirehair pointer.  We feed this food during hunting season due to his increased metabolic needs.  He burns so many calories, he eats 8 cups of this food a day (with zeal).  We use the large bites to help keep the tarter and plaque off of his teeth (and to slow his eating).  Due to the high quality of this food, he can keep up his energy, keep his weight up, and recover more quickly from scrapes/bumps from running the field.  Our vet's exact words were, "Your dog is an example of perfect health."  You may think the price on this food is high, but it is worth it.  You get what you pay for.  Also, consider the canned version of this food.  It is a nice way to feed/hydrate a dog after a long day hunting - just give them an hour to settle down first.  On a side note, we feed Diamond Naturals Beef and Rice in the off season.  We have no digestive issues transitioning from one to the other (we switch over a period of a few weeks).

If you like the flavor of green tea and like your beverage iced you will enjoy this beverage.  I like the taste of green tea and I also like the health benefits of green tea.  I mix this with ice water and splenda.  It is a refreshing summer beverage.  I like that it dissolves easily and is packaged in small packages.  It is convenient and easy to use.
