The first ingredient in this dog food is corn. Corn is an inexpensive and controversial cereal grain. And aside from its energy content, this grain is of only modest nutritional value to a dog.

For this reason, we do not consider corn a preferred component in any dog food.

The second ingredient is chicken by-product meal, a dry rendered product of slaughterhouse waste. It’s made from what’s left of a slaughtered chicken after all the prime cuts have been removed.

In addition to organs (the nourishing part), this stuff can contain almost anything — feet, beaks, undeveloped eggs — anything except feathers.

On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh chicken.

In any case, although this item contains all the amino acids a dog needs, we consider chicken by-products an inexpensive, lower quality ingredient.

The third ingredient is animal fat. Animal fat is a generic by-product of rendering, the same high-temperature process used to make meat meals.

Since there’s no mention of a specific animal, this item could come from almost anywhere: roadkill, spoiled supermarket meat, dead, diseased or dying cattle — even euthanized pets.

For this reason, we do not consider generic animal fat a quality ingredient.

The fourth ingredient is beet pulp. Beet pulp is a controversial ingredient, a high fiber by-product of sugar beet processing.

Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.

We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most dog foods is entirely acceptable.

The fifth ingredient is soybean oil is red flagged here only due to its rumored (yet unlikely) link to canine food allergies.

However, since soybean oil is high in omega-6 fatty acids and contains no omega-3’s, it’s considered less nutritious than flaxseed oil or a named animal fat.

The sixth ingredient is lactic acid, a compound found naturally in many living organisms. It’s likely added here to adjust the pH of the product which (in turn) reduces the growth of unwanted biological contaminants.

The seventh ingredient is dried egg product, a dehydrated form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that have failed to hatch.

In any case, eggs are easy to digest and have an exceptionally high biological value.

The eighth ingredient is flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also rich in soluble fiber.

However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.

From here, the list goes on to include a number of other items.

But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this product.

With two notable exceptions

First, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.

And lastly, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Non-chelated minerals are usually associated with lower quality dog foods.

Hill’s Science Diet High Energy Dog Food
The Bottom Line

Judging by its ingredients alone, Hill’s Science Diet High Energy Dog Food looks like a below-average dry product.

But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.

The dashboard displays a dry matter protein reading of 30%, a fat level of 27% and estimated carbohydrates of about 35%.

And a fat-to-protein ratio of about 91%.

Near-average protein. Above-average fat. And below-average carbs when compared to a typical dry dog food.

Even when you consider the protein-boosting effect of the flaxseed, this looks like the profile of a kibble containing a moderate amount of meat.

Bottom line?

Hill’s Science Diet High Energy is a plant-based dry dog food using a moderate amount of chicken by-product meal as its main source of animal protein, thus earning the brand 3 stars.

Recommended.

However, with 27% of the total calories in this recipe coming from fat versus just 30% from protein, this food may not be suitable for every animal.

    It definitely still exists. I work at a shelter and we got a bag with our last Hill’s shipment.

    That was SOOOO hard to find. I mean, I had to read all the way down to the… wait… nope, it was the very first link when doing a Google search for “hill’s science diet high energy”.

    Before ranting and raving how about doing a little bit of research, that way you don’t sound like a fool?

  • Pattyvaughn

    There is one reason GREED nothing else.

  • Shawna

    You wrote “There is no reason for dog food manufacturers to spend milliions of dollars of product research and development if all they are going to do is slap together some waste products.”

    How many times can we “like” a post :).. Two BIG thumbs up!!!

  • Almostavet

    “In a nutshell, chicken by-products are those unsavory leftovers usually considered “unfit for human consumption”.

    In addition to organs (the nourishing part), this stuff can contain almost anything — feet, beaks, undeveloped eggs — anything except quality skeletal muscle (real meat).
    YOU need to check your ideas of “unfit for human consumption”!

    The following is taken from the AAFCO definitions!

    Chicken By-Product Meal – consists of the ground, rendered, clean parts of the carcass of slaughtered chicken, such as necks, feet, undeveloped eggs and intestines, exclusive of feathers, except in such amounts as might occur unavoidable in good processing practice.

    As you can see by products are what we here in the US don’t normally consume! Go to Southeast Asia or Africa and you will find people eating chicken necks, undeveloped eggs and the intestines routinely!

    There is no reason for dog food manufacturers to spend milliions of dollars of product research and development if all they are going to do is slap together some waste products.

    There is a lot of influential misinformation going around and opinions on a blog can be considered as such.

    The administrator of this site, who is the reviewer, could not possibly have time to update every food every time something changes. He has a list of new foods to update as well. People can read this website for information on how to find a good food & figure out for themselves if a food is of good or bad quality.

  • Nick

    if it does still exist, it sure isn’t in any pet stores. They have changed their recipes, regardless. I am not sure why people trust their vet for everything but diss food that vets researched and created…my dogs live until VERY old…feed homemade meals on occasion and feed Science Diet. The only thing to improve it would be to make it organic but that would probably triple the price. None of the brands but Castor & Pollux are organic USDA but some try to play it off as if they were…

  • Nick

    This does not exist anymore. Hill’s has updated their products. That is more than I can say about this website here, please update your reviews! And Hll’s does not use slaughterhouse waste…not all pet companies are equal.

  • Mary

    I buy dry grain free Science Hill, plus i give my 2 dogs, veggies, dry cranberries , boiled chicken mix everything together. they love it. they only get a cup aday of the mix. they are 6 pounds

  • JellyCat

    It’s just awful food as usual.

  • Lauren Monsey Nagel

    I think it’s pathetic that we pay for this stuff.

  • Hound Dog Mom

    It’s considered “high energy” because it’s higher in fat and protein and more calorie-dense than the other Science Diet formulas. It has 30% protein and 27% fat versus 25% protein and 16% fat in the original adult formula. It has 560 kcal. per cup while the original adult formula has 362 kcal. per cup. Some pet food manufacturers are beginning to add lactic acid as a preservative and to control microbial growth (i.e. salmonella).

  • Jerry

    Never saw lactic acid in dog food before, interesting.

    While the dry matter reading on this food appears ok I was surprised to see it get 3 stars based on the first 5 ingredients being indicated as controversial.

    Would be interested to see the company’s website to see what actually makes it “high energy.”
