What critics say

Reviewers praise
- Kibble is easy to chew and digest, with small-bite options for smaller mouths
- Free of artificial colors, flavors, and preservatives across the reviewed lines
- Dogs show good coat condition and steady energy on the food
Reviewers push back
- Not ideal for dogs with sensitivities to chicken or barley

- Costs more than many competing dog food brands
Reviewers see Hill's Science Diet as a trusted, vet-recommended brand that makes gentle, consistent food dogs tolerate well over years of feeding.
Reviewers praise
- High protein content from multiple named animal sources, including fresh meat, organs, and wild-caught fish, used across the full product lineup
- No artificial preservatives, dyes, or synthetic fillers — ingredients are described as clean and recognisable on the label
- Vacuum-sealed, resealable packaging across the range preserves freshness without chemical preservatives
Reviewers push back
- Limited retail availability — the brand is absent from many mainstream pet chain stores, requiring owners to seek out specialist retailers
- Resealable bag closure is faulted for being difficult to seal properly on first use
- Counterfeit product sold through grey-market online channels is a documented brand problem that complicates purchasing decisions
Reviewers across dog and cat content agree that Orijen is a genuinely premium, biologically appropriate pet food brand built on clean, high-protein ingredients and a long record of safety — though its limited retail footprint and premium positioning are consistent friction points.

Hill's Science Diet receives mostly neutral coverage with product announcements and reviews, though market headwinds in the sluggish pet category present a notable challenge.
Orijen's FreshPrey launch generates mostly positive coverage, but faces criticism over false advertising claims and premium pricing concerns.
