Some of you commented on my last post about if any of you have noticed any changes with Wellness food. This company is so awesome I just have to say that first of all. I called them and they told me that they have not had any formulation changes at all and don't plan to in the future. They are very satisified with their product and know that there is no room for change. Great to know. They also told me that since their food is all natural that the flavor, odor, and color will be different from batch to batch because they don't put any binders in the food to keep it uniformed looking, smelling, etc. Great to know too. So that is why this bag of food I bought smells a litte different. They checked the code on the bottom and was able to tell me when it was made and let me tell you its probably the freshest dog food I have ever bought. Just for calling in with my questions they are sending me free samples....again......and coupons. I don't know of any company that does this. So I would say Wellness is an awesome company. Just wanted to update you all and thank you for taking the time out and responding to my post!
