Review: Hills Science Diet ZD is Life Changing for my Dog! - My dog was already 4 months old when I adopted her via a local rescue. She and sister had been taped into a cardboard box and thrown onto a landfill! Took the landfill awhile to discover them. Then only caught them when they realized they were returning to the box at night to sleep. Perhaps related to this, once I brought her home, it quickly became apparent she had allergies. Testing at 1 year of age revealed 39 strong reactions to all sorts of things, including several types of proteins, meats, most grains and/or ingredients typically found in commercial dog foods. She requires this hydrolyzed formula which is veterinary recommended and does not contain peas, rice, etc. So thankful it exists! Now 6, she is living her best life! She is one of the smartest, nicest dogs I have ever had! It also influenced me to choose to choose Hill’s cat food for the kitten I adopted :)
Review: It Really Works! - This is the only food that we can feed Syrie that she won't throw up. We've tried a whole bunch of other sensitive stomach foods but end up back with the Hills Prescription.

### ⭐⭐⭐⭐⭐ Product outstanding/ get Amazon to deliver
*by K***R on July 18, 2026*

Product was and is great. Using USPS to deliver is lousy. We have had to drive to pick up as they simply drop a slip and do not even come to door. Hopefully delivery is now changed.
