My dog loves this food, and she has maintained her healthy weight for many years.  The vet is very happy with her general health, coat, and teeth.  Having the 16lb bag sent directly to my home without any shipping charges is terrific!  The 16 lb. size is not available in my area.

I have an otherwise healthy and active 1 year old Rottweiler.  I switched her from Blue Buffalo to Canidae, as it came highly recommended by the holistic pet store I frequent (they are going to be the next to get an earful from me!!!).  Shortly after, I noticed her stool became loose, which is common when you change a dog's diet (I mixed the new food with the old for a week, gradually increasing the amount of the new).  I figured it would get better after a few days.  In fact, it became increasingly worse to the point where spots of blood where showing up in her stool.  I took her to the vet thinking at this point she must have picked up a parasite.  The test came back negative.  My vet thought it must have been something she ate and recommended I feed her chicken and rice for a week to even her out.  I did this and the problem was solved.  After a week I put her back on her regular food- Canidae- and the problem she was having before began to return, albeit gradually.  We have now started to see spots of blood again.  This convinced me it was not just "something she picked up," but the dog food itself.  Now I have learned there is actually a CLASS ACTION SUIT against this dog food maker for the exact problem I described- in some cases people's dogs even died.  I will NEVER purchase this brand again and am switching my dog immediately back to Blue Buffalo- this time no mixing!!
Negative

Melitta's Riviera Sunset Decaffeinated Ground Coffee turned out to be a good basic coffee - not bitter, not burned-tasting, a well-rounded mellow brew that tastes like real coffee. I had it this morning with almond milk, stevia and a pinch of cinnamon, and though I'd had a bad night and didn't even know if I could handle coffee, it was delicious and easy on a morning tummy. Besides brewing it alone to get a nice decaffeinated coffee for night-time drinking (especially in the winter), we've been mixing it with regular coffee in various blends, depending on our caffeine-related needs at the time.  The packaging is practical and easy to re-close and the grind is good for my automatic coffeemaker. I will buy this one again.
