How to choose the best dog food for your pet

Deciphering all the pet nutrition information on the internet can seem like an impossible task. It can range from confusing to completely contradictory.

We spoke to real pet nutrition researchers to understand what actually matters. Good news: it isnt as complicated as it seems.

The most important part of choosing a food is actually monitoring your pet, said Dr Teresa Hollands, senior lecturer in veterinary nutrition at the University of Surrey. If you're feeding your pet a particular brand of food, and they have plenty of energy and seem well in themselves, then you are on the right track.

Dr Nigel Kendall, lecturer in nutrition at the University of Nottingham, agreed: If your pet is on completely the wrong diet, then there will be physical signs.

Signs that your pet is eating a nutritious diet, and the right food for their needs, include:

• good overall health
• plenty of energy
• good sleeping habits
• regularly passing firm stools
• maintaining a healthy weight.

How to feed your dog the best and healthiest diet

As well as choosing the right food, you can also maximise the nutritional value of your pets diet by feeding them in the right way.

We spoke with Dr David Gardner, professor of physiology at the University of Nottingham, to find out more:

Choosing a complete food

Start by making sure you are feeding your pet a complete food, he said. Thats really important, but it isnt always clearly labelled.

Complete foods are designed to give your pet all the nutrients they need, so you can feed them the same thing every day without causing a nutritional imbalance or deficit.

Weighing your pet food

David also highlighted the importance of weighing your pets food every time you feed them.

Remember, you may not notice that you're overfeeding your pet if you increase the size of their feed very slightly each day.

Varying your pet food

If you want to take additional steps to ensure your pet is getting the best nutrition, David also suggested varying the food you give them, provided that this doesnt upset their stomach.

These changes could be as small as varying the flavour of food that you give to your pet.

If you buy a bag of lamb dog food one month, try the chicken next time, David suggested.

If you do want to try changing the type or brand of your pet food, remember to do so gradually. Your pet's meal should be no more than 25% new food for the first couple of days, increasing over the course of a week.

Dogs can be fussy, so know that varying your pet food is not essential. The main thing is that they eat and enjoy their food and that it's nutritionally complete.

Is wet or dry dog food better?

Both wet and dry foods can be nutritionally complete, meaning that they should contain all the nutrients your pet needs. That means there is no significant advantage to either food type.

David recommended feeding your pet a mixture of wet and dry food.

Evidence suggests that there are slight differences in the nutritional composition of wet and dry food. That means you are going to cover more nutrients if you mix them together.

If you want to feed your dog exclusively one type of food, then wet food does tend to be more appealing. However, it is often more expensive and it can predispose pets to dental disease.

In contrast, dry food is beneficial to dogs teeth and gums, and it is usually easier and cheaper to use and store. Just make sure that your dog has access to plenty of fresh water, as they will not be getting hydration from their food.

Can dogs be vegan?

Yes, provided you are careful about the type of food you give them.

There are commercial dog foods available that are vegetarian or vegan and nutritionally complete.

Some people may want to prepare homemade vegetarian or vegan meals for their dog, which is not typically recommended by experts.

This is because evidence suggests that homemade food (including meat-based diets) is typically not nutritionally complete even when people follow recipes labelled as such.

Is raw food good for dogs?

Raw pet food has become more popular over the past few years, especially for dogs, but experts don't generally recommend it.

I would not recommend a raw food diet due to the risk to human health, says Dr Heather Bacon, dean of veterinary medicine at the University of Central Lancashire.

Bacteria present in raw meat can include salmonella, listeria, campylobacter and E-coli. These cause significant illness in humans and animals, particularly young, old and immune-compromised individuals.

These can be spread around the house during food preparation and eating. They can also be passed from animals to humans if your pet kisses your face after eating.

All of these bacteria are destroyed when meat is correctly cooked.

How much should my dog weigh?

According to a 2022 survey by UK Pet Food, 50% of dogs (and 43% of cats) are overweight or obese.

Your pet being overweight can have a huge impact on its quality of life, including limiting their ability to exercise or sleep properly. According to the RSPCA, it also predisposes them to illness including:

• diabetes
• heart disease
• cancer.

How to if tell your dog is overweight

Dr Teresa Hollands recommends an easy method for checking your pets weight.

Create a fist with your hand, and feel your knuckles with your fingers, she said. If your pets ribs feel like that, they are underweight.

Then lay your hand flat, and feel your knuckles again. If their ribs feel like that, they are the perfect weight.

Finally, keep your hand flat, turn your hand over, and run your fingers over the pads on your palm at the base of your fingers. If their ribs feel like that, they are overweight.

Physical signs that your dog is overweight

• Very thin(more than 20% below ideal body weight) Ribs, spine and hip bones easily seen (in short-haired pets), obvious loss of muscle bulk, no fat can be felt under the skin.
• Underweight (10-20% below ideal body weight)Ribs, spine and hip bones easily seen, obvious waist and abdominal tuck, very little fat can be felt under the skin.
• IdealRibs, spine and hip bones easily felt, visible waist and abdominal tuck, small amount of fat can be felt.
• Overweight(10-15% above ideal body weight): Ribs, spine and hip bones are hard to feel, waist barely visible, broad back, layer of fat on belly and at base of tail.
• Obese (more than 15% above ideal body weight)Ribs, spine and hip bones extremely difficult to feel under a thick layer of fat, no waist can be seen and belly may droop significantly, heavy fat pads on lower back and at base of the tail.

How we rated dog food brands

To uncover the best and worst dog food brands, in July 2023 we surveyed 2,304 Which? members who had bought dog food recently, and asked all about their experiences with their chosen brand.

We asked them to rate the brand on various attributes including value for money, how their dog responded to the food, and its perceived wellbeing on the food.

Overall customer scores are based on how satisfied customers were with the brand overall and whether or not they would recommend it.

Review of Royal Canin Size Health Nutrition X-Small Dry Dog Food

Royal Canin Size Health Nutrition X-Small Dog Food receives the Advisors mid-tier rating of 3 stars.

The Royal Canin Size Health Nutrition X-Small product line includes the 4 dry dog foods listed below.

Each recipe includes its AAFCO nutrient profile when available Growth (puppy), Maintenance (adult), All Life Stages, Supplemental or Unspecified.

Recipe and Label Analysis

Royal Canin Size Health Nutrition X-Small Adult was selected to represent the other products in the line for detailed recipe and nutrient analysis.

Label and nutrient data below are calculated using dry matter basis.

Royal Canin Size Health Nutrition X-Small Adult

Estimated Dry Matter Nutrient Content

Brewers rice, corn, chicken by-product meal, chicken fat, corn gluten meal, wheat gluten, natural flavors, dried chicory root, vegetable oil, fish oil, psyllium seed husk, potassium chloride, calcium sulfate, monocalcium phosphate, salt, l-tyrosine, l-lysine, calcium carbonate, dl-methionine, fructooligosaccharides, sodium tripolyphosphate, l-arginine, choline chloride, vitamins [dl-alpha tocopherol acetate (source of vitamin E), l-ascorbyl-2-polyphosphate (source of vitamin C), biotin, d-calcium pantothenate, vitamin A acetate, pyridoxine hydrochloride (vitamin B6), niacin supplement, folic acid, thiamine mononitrate (vitamin B1), vitamin B12 supplement, riboflavin supplement, vitamin D3 supplement], magnesium oxide, trace minerals [zinc proteinate, zinc oxide, ferrous sulfate, manganese proteinate, manganous oxide, copper sulfate, calcium iodate, sodium selenite, copper proteinate], l-carnitine, rosemary extract, preserved with mixed tocopherols and citric acid

Fiber (estimated dry matter content) = 3.5%

Red denotes any controversial items

Ingredient Analysis

The first ingredient in this dog food is brewers rice. Brewers rice is a cereal grain by-product consisting of the small fragments left over after milling whole rice. Aside from the caloric energy it contains, this item is of only modest nutritional value to a dog.

The second ingredient 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 third ingredient is chicken by-product meal, a dry rendered product of slaughterhouse waste. Its made from whats left of a slaughtered chicken after all the choice cuts have been removed.

In addition to organs, this item can also include feet, beaks, undeveloped eggs and almost anything other than prime skeletal muscle.

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

The quality of this ingredient can vary, depending on the caliber of the raw materials obtained by the manufacturer.

The fourth ingredient is chicken fat. This item is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.

Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesnt sound very appetizing, chicken fat is actually a quality ingredient.

The next ingredient is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.

Although corn gluten meal contains 60% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like this can notably boost the total protein reported on the label a factor that must be considered when judging the actual meat content of this dog food.

The sixth ingredient is wheat gluten, another plant-based protein booster.

Although wheat gluten contains 80% protein, this ingredient would be expected to have a lower biological value than meat.

After the natural flavor, we find chicory root. Chicory is rich in inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.

Not only is inulin a natural source of soluble dietary fiber, its also a prebiotic used to promote the growth of healthy bacteria in a dogs digestive tract.

The next ingredient is vegetable oil, a generic oil of unknown origin. The ratio of omega-6 to omega-3 fats in any oil is nutritionally critical and can vary significantly (depending on the source).

Without knowing more, its impossible to judge the quality of an item so vaguely described. However, compared to a named animal fat, a generic vegetable oil cannot be considered a quality ingredient.

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 Royal Canin product.

With 4 notable exceptions

First, we find fish oil. Fish oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids. These two high quality fats boast the highest bio-availability to dogs and humans.

Depending on its level of freshness and purity, fish oil should be considered a commendable addition.

Next, this recipe contains fructooligosaccharide, an alternative sweetener¹ probably used here as a prebiotic. Prebiotics function to support the growth of healthy bacteria in the large intestine.

In addition, we find sodium selenite in this product. Sodium selenite is a controversial form of the mineral selenium. Sodium selenite appears to be nutritionally inferior to the more natural source of selenium found in selenium yeast.

And lastly, this food includes chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.

Nutrient Analysis

Based on its ingredients alone, Royal Canin Size Health Nutrition X-Small Dog Food looks like an average dry product.

The dashboard displays a dry matter protein reading of 24%, a fat level of 18% and estimated carbohydrates of about 50%.

As a group, the brand features an average protein content of 26% and a mean fat level of 18%. Together, these figures suggest a carbohydrate content of 48% for the overall product line.

And a fat-to-protein ratio of about 68%.

Which means this Royal Canin product line contains

Near-average protein. Above-average fat. And near-average carbs when compared to other dry dog foods.

When you consider the protein-boosting effect of the corn and wheat glutens, this looks like the profile of a kibble containing just a moderate amount of meat.

However, with 37% of the total calories in our example coming from fat versus just 21% from protein, some recipes may not be suitable for pets on a low-fat diet.

Our Rating of Royal Canin Size Health Nutrition X-Small Dog Food

Royal Canin Size Health Nutrition X-Small is a grain-inclusive dry dog food using a moderate amount of named by-product meal as its dominant source of animal protein, thus earning the brand 3 stars.

Recommended.
