Complete, protein-based nutrition. My dogs love this...although I'm not sure the pibble actually tastes it, she inhales it so fast. ;) Regarding the other users who have had diarrhea issues: My gastro-picky GSD (is that a word? I think other GSD owners will understand!) has had this as well. Initially, I overfed this food, thinking that he needed to be eating the same amount as he had been eating the other stuff. You feed MUCH less of this product. It is nutrient-dense, and not all filler like other foods. If you over-feed, you increase the risk of unpleasant side effects. It's a bit pricey, and I haven't broken down the cost per day, but since you feed less it might be competitive with other brands if someone was inclined to "run the numbers".

Ex Output:
Positive

My 11 month old Welsh Corgi figured this out the first time she took it from my hand. However within a matter of hours she had the rope soaking wet and chewed mostly in half. The rope is now soft and not a useable tool to get the treat out. The knot was also too big and frayed to let any of the snacks out of the bottle. You should also know that the snacks this company makes are too big for the extra small bottle.

Ex Output:
Negative

Hi, I have to have black tea everyday. I have done it in the past 25 years and it's a habit of mine. Ahmad tea is one of my favorite brands and I highly recommend it if you like black tea. I think this is going to remain my favorite for the next 100 years or so :)
