highest cal/cup for price/quantity

I needed a food with High calorie content, for a good price, and most importantly, a nice ingredient list. Diamond Naturals Extreme Athlete tics all of those boxes. I have two dogs; 1 mixed breed & 1 GSP. I used to feed my 58# mixed breed (1 3/4 cups daily) a very pricey brand - about $70 a bag, that would last her ~2months, but when I adopted my 66# GSP (3cups daily) last year we started going through food fast. My German Short Haired Pointer needs a lot of calories due to his activity level. He was eating through $140 a month on our previous brand of dog food - and frankly, through my pockets. I needed a food that wasn't going to break the bank and I prefer an ingredient list you can pronounce - price vs. quality vs. quantity - this food has it all. 2 1/2 40# bags lasts us about three months. *Disclaimer: neither of my two dogs are picky eaters & eat raw/dehydrated for breakfast, kibble is fed only during PM mealtime. Cons: I wish this food came in other proteins/flavors because my gsp has softer bowel movements with Chicken and firmer stools with lamb. My mixed breed has always done well with chicken so she doesn't experience soft stools with this product. Minus 1 star for lack of variety. Otherwise overall satisfied with this product (:

Has the look and feel of cheap food

My dog did not like this food. My dog used to run to the food bowl and not leave until the meal was finished, and rarely had stomach problems. Now she will leave the bowl after a couple bites and come back later. As soon as I opened the bag it seemed like lower quality food than what we were previously feeding. We have since switched back to our old food. would not recommend

Bad Digestion Over Time

This is one of those versions of dry food that over time gives your dog the runs. My other smaller dog did not seem to have this issue, but once I put her on natural food, the problem went away.

A Win for My German Shepherd

I have a German Shepherd that is very active. He's never still. On the large breed food, he wasn't thickening up. His vet told me he needed more protein. He likes this kibble, and his ribs are no longer showing. He is very fit on this food.

Stopped Eating

My dog all of sudden refuses to eat this food. but only since I started feeding him this last bag I received. I am worried there could be something wrong with the food. I found a few pieces that appear to look moldy.

Great experience!

Ordered a 40lb pound bag for a way cheaper cost than my normal trip to my usual dog food provider. My bully is healthy, definitely ordering again.

Great Food!

We have 2 really nice English Pointers that hunt and play hard. This food put weight on our smaller pointer/he needed it, and kept the weight on the larger one. We will cut their ration back during the off season but, the food seems to work well and they eat it up. We do put some hot water on it and let it soak for a few minutes, when it is really cold outside to make a nice bit of warm gravey.

Our dogs love this food

We switched to this dry dog food recently due to the main ingredients and recommendations we found. Our two wirehaired pointing griffons were very interested when the box arrived and they appear to enjoy it more than our previous brand.

Extreme Athlete is the best

Excellent dog food but I found it $4.00 cheaper at a store. In the past it was a great deal at $43 delivered because that was the same price to buy in stores. Now it's around $47.
