[EX Q]: I have a pure breed GSD and had problems for years with upset stomach, eating grass and throwing up bile in the morning and then would not eat as her stomach was too upset.  It finally dawned on me that due to throwing up bile in the am was that the food was not staying with her.  I even tried feeding her before going to bed at night and still did not work.  I tried Evo and I could not believe the change.  She does not get us up at night to go outside.  She was having 3-4 bowel movements every day and now she has 1 or sometimes 2.  I have had her on the Evo large bites for almost a year now and she has not been sick once.  It is the higher protein in this food that stays with her longer and has made all of our lives so much better.  Thank you, thank you EVO!!!
[EX A]: OMG, What a life saver

[EX Q]: Both of my dogs had trouble with this formula, allergy wise.  It took me a couple of days to realize that their itching was related to the food.  Needless to say I won't buy this product again.
[EX A]: I won't purchase again.

[EX Q]: I love these crackers!  Perfect snack for when I need something salty/crunchy instead of potato chips or other greasy snack.  I eat them a lot to hold me over between meals.  The price on amazon is great compared to my local markets.  Highly recommended!
[EX A]:
Excellent snack
