My pitty, puppy at the time came to me with bad tummy problems. Tried 3 different foods with no luck. Until diamond puppy food!! It was like omg this is the one. No more tummy problems at all!!! Fast forward he’s no longer a puppy so I switched to diamond pro89 had no problems switching it up in fact my 13 year old min pin loves it and he’s not acting his age lol ever since I started feeding him it too!!

We mix this with the Diamond Performance Formula and they really like it. Good food, good for them, and affordable. We buy a bag of each (total of 80lbs.) and mix them equally. This feeds all 3 of our dogs (38lb 9yr old Beagle, 82lb 14mth old Great Pyrenees/Pitt mix, and 120lb 3yr old Giant Schnauzer) for about 5 1/2 wks. This mix gives them beef, chicken, and pork! They will even eat this without any of the toppers. WOW!!

Pet sick

Our last bag made our dog sick, we had to throw the whole thing away right after receiving it. Luckily chewy was super helpful.

Great dog food

Not a ton of additives and the ingredients aren't processed. Our dogs love it. Also, the same price as our old dog food that was only 28 pounds. This is a 40 pound
