This box of dog food was thrown over the corral gate where donkeys tore through the box. Dog food is not good for donkeys. Most drivers just place the box on my front porch which is less then 100 ft from this box was thrown. My driveway is a loop so the driver had to pass my front porch. Please don't ever do this again.!!!

I usually have good experiences with Hill's Science Diet products but my silver lab doesn't like the food so far. He has a sensitive stomach and sometimes seems to get bored with the same food. He is slow to eat this so far. I'm hopeful he likes it more in a few more attempts.

The ONLY one that worked

Our German Shepherd puppy, from day one, was never excited to eat her food (unheard of, I know). She'd take all day to graze on her bowl, and would often have gas and diarrhea. We tried so many different foods, which was exhausting because switching food can be such a process. Nothing helped with her stomach situation, and she still didn't care to eat. We decided to give this one a shot- and we saw an instant change. Her stools became firm and regular and she was incredibly excited to eat! After YEARS of zero interest in food, she's regularly eating on a schedule and is eating the moment it's served to her. We've stayed with it ever since and our now 6 year old girl remains "regular" and happy!

Remind employees to be careful when cutting the box or pallet of food , this second time now the bag cut and they put tape over the cut. I don’t want to give my dog anything that could be contaminated so I will feed this one to wildlife behind my home.

I have a dog that had diarrhea for a year. We tried the Hill's Microbiome prescription food which helped immensely to help her stomach get back on track. I then switched to this food and she continued to have great stools. We are no longer on this food, but I always keep a bag on hand in case one of my dogs has stomach upset. It's really easy to transition to and the dogs like the taste.
