Verified Review: User Experience

Hill’s Science Diet Perfect Weight

Many users saw improvement in their dog’s energy level and weight within just weeks. Though some did point out that they feel the product is pricey they could noticeably see the improvement in their dog and understood and appreciated the difference this made for their furry friend.

“I was recommended the Hill Science Diet Healthy Weight by my aunt. It’s been 2 weeks and our lady lab is doing amazing! Her energy level has skyrocketed, and she loves the food. That’s the big difference I can see with her in a short time, however my mom has already noticed her weight loss too (she does not live with me so doesn’t get to see her often.) I highly recommend it for your pets! “

Hill’s Science Diet Adult Sensitive Stomach & Skin 

There were many rave reviews about the improvement to their dog’s skin and digestion in a short amount of time. Negative reviews surrounded a formula change and not being able to slowly introduce the food back in. Any time you’re either changing your dog’s food or need to reintroduce a food that’s formula has changed, it’s recommended to do this gradually over a period of time so your dog has time to acclimate to the changes.

“Hills was recommended to start her off on but once I finished the sample bag I decided to try this one out due to the sensitivity. It’s been 6 months now and her coat has improved tremendously. Her confidence shows more now, and the food does not give her gas at all as opposed to other brands that I’ve sampled. Overall a really wonderful product and I cannot wait to see what another 6 months will do for my princess.”
