“Customer Review: My dog absolutely loves this Kibble. He’s a Medium-Large sized dog but the difference that we notice while using the small breed variant is the size of the kibble. Easy for him to chew! Expensive but worth every penny! All of the 62 shipments Ive had so far have arrived in perfect quality, too!”
“Customer Review: Yes it cost a little more but its worth it! All 4 of my Chihuahuas have some form of skin or stomach issues. This food makes those outbreaks so much better. They are VERY picky and will even eat this dry. Ive decided to just feed it to them all the time now. Great Stuff!”

Customer Reviews
“Customer Review: I have been using this food for my 18yo chihuahua for a while and he likes it and it has helped him maintain his health. However, that being said, the handling of the cans of dog food leave something to be desired. Several cans were badly damaged from the last order. I had the same problem with Chew”

Complete Buying Guide for Science Diet Dog Food
Essential Factors We Consider
When evaluating Science Diet dog food reviews, we focus on ingredient quality, digestibility, life stage appropriateness, and real-world results. We prioritize formulas with real meat as the first ingredient, minimal fillers, and added benefits like prebiotics, omega fatty acids, and antioxidants. Veterinary endorsement and clinical research also play a key role in our recommendations.
Budget Planning
Science Diet is a premium brand, so expect to pay more than store-brand kibble—but the investment often pays off in fewer vet bills and better overall health. Wet food options cost more per serving but can be used strategically as toppers. Look for bulk discounts on larger bags or subscribe-and-save options on Amazon to reduce long-term costs.
