Original Crunchy Dog Treats, 11-oz bag
Graded by The Sniff System
Hill's Prescription Diet Original Crunchy Dog Treats are dry treats for dogs, primarily featuring chicken and pork protein.
The formula has undergone AAFCO feeding trials, which is a strong indicator of nutritional adequacy. It also includes egg product and chicken liver flavor, contributing to diverse, bioavailable protein sources.
The formula is notably low in protein and fat on a dry matter basis. It's also a plant-protein-dominated formula, with whole grain corn as the first ingredient, and it lacks a declared omega-3 source.
Good fit for dogs whose owners prioritize AAFCO feeding trials for treats. Less ideal if you want a meat-first, high-protein treat.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. Good fit for active large sporting breeds, including the Labrador Retriever, navigating weight management. Caloric density is not declared, with crude fiber at 22% (above the catalog median, supports satiety). According to the Association for Pet Obesity Prevention's 2023 survey, 59% of dogs in the United States were classified as overweight or obese by their veterinary healthcare professional, representing an estimated 55 million dogs (APOP, 2023) .

At 44/100, this formula sits below where we look for everyday picks. The lift comes from AAFCO compliance, worth 8 points to the final number: AAFCO feeding trial substantiation for not stated. The ceiling on this score is 49, set because the guaranteed analysis falls below AAFCO's minimum nutrient profile. The cap isn't the binding constraint here. Protein quality would also need to improve to reach the next band.
