Toothpaste/Shampoo conglomerate Colgate-Palmolive make hundreds of millions of dollars selling pet foods made largely of rice and corn. Branding these ingredients with the word “Science” doesn’t necessarily mean right for your pet, it means they’re scientifically formulated within guidelines to produce a product for the highest markup possible. It’s a winning formula from a company who’s done incredibly well with products we use “every day”.

Our previous review was negative, so for this revised edition we’ll focus on a formula aimed at healthy, active adult dogs – Hill’s Prescription Diet Active Adult. Consider this the best of the bunch, so if this doesn’t stack up, the other Science Diet formulas probably won’t either.

The first ingredient in this product aimed at active carnivores is… corn 🤷

That’s disappointing, and an immediate insight into how the company makes so much money. Corn is one of the cheapest inclusions we can find in a pet food, and a very cheap way to boost protein levels in the food without using meat.

The fourth ingredient is also corn, labelled in this instance as corn gluten meal (or CGM). The 5th ingredient (Beet Pulp) won’t amount to much of the food, which suggests the first four ingredients are the majority of the product. The corn is potentially 50% of the food, possibly more.

The 2nd and 3rd ingredients are more species appropriate, a combination of chicken by-product meal and pork fat. These are better inclusions which make Active Adult a better formula than others in the range.

Moving on from the four main ingredients we find a long list of vitamins, minerals, oils, preservatives, et al. Dog foods need to meet minimum nutrition guidelines (usually based on AAFCO standards). On many pet foods you find “vitamins and minerals” listed, usually in the form of a pack/powder sourced overseas. With Hill’s you can expect better inclusions which have been hand picked to work with the formula.

Also with a large global manufacturer you can expect a higher standard of manufacture.

Overall this is one of the better Hill’s Science Diet formulas, but we can’t ignore the significant amount of corn. Many other Hill’s formulas use wheat and rice to keep production costs down, both of which are arguably worse than corn.
