Dog Food Ingredients to Avoid (And What NZ Brands Actually Put In the Bag)

Title tag: Dog Food Ingredients to Avoid (And What NZ Brands Actually Put In the Bag) Meta description: Not all dog food is created equal. Here are the ingredients that should make you put the bag back on the shelf, and what to look for instead.

Pick up almost any bag of dog food in a NZ supermarket and the front tells you a great story. Natural. Premium. Wholesome. Flip it over and read the ingredients list. That's where the real story is.

Most dog owners don't read labels because the terminology is confusing by design. This guide cuts through that. Here's what to avoid, what to look for, and how to spot the difference quickly.


Why Labels Are Designed to Confuse You

Dog food labelling in NZ follows relatively loose standards. Manufacturers aren't required to specify the source of every ingredient, which means terms like 'animal by-products' or 'meat meal' can legally cover a wide range of materials.

The ingredient list is ordered by weight before processing. Fresh meat is heavy because it contains water - after cooking it shrinks significantly. Once you know what to look for, reading a label takes about 30 seconds.


Ingredients to Avoid

Unnamed meat meal and animal by-products

Meat meal can be fine when the source is named: 'chicken meal' or 'lamb meal' tells you what's in the bag. 'Meat meal' or 'animal meal' without a species specified is a red flag. These are often rendered from multiple unspecified sources.

What to look for instead: Named proteins - chicken meal, lamb meal, salmon meal.

Corn, wheat, and soy as primary ingredients

These are cheap calorie sources used to bulk out a product inexpensively. Dog digestive systems are designed for animal protein, not grain. If corn, wheat, or soy appears in the first three ingredients, the food is grain-padded.

What to look for instead: Animal protein in the first position.

Artificial preservatives: BHA, BHT, and ethoxyquin

These synthetic antioxidants extend shelf life. BHA and BHT have raised concerns in animal studies. Ethoxyquin was originally developed as a pesticide. Natural alternatives like mixed tocopherols and ascorbic acid do the same job without the concerns.

What to look for instead: Mixed tocopherols, ascorbic acid, rosemary extract.

Artificial colours and flavours

Dogs don't choose food based on appearance. Artificial colours serve no nutritional purpose. Any food that needs artificial flavour enhancers to be palatable is compensating for low-quality base ingredients.

What to look for instead: Nothing. These ingredients simply shouldn't be there.

Added sugars

Corn syrup, glucose, and similar sweeteners appear in some dog foods to improve palatability. They contribute to weight gain, dental disease, and blood sugar instability. If sugar appears anywhere in the ingredient list, that's a flag.

What to look for instead: Palatability from quality protein, not sugar.

Salt as a primary flavour enhancer

Sodium is a necessary part of any dog's diet, and sodium chloride appears on most dog food labels for good reason. The concern is when salt appears prominently high in the ingredient list, suggesting it's being used in larger-than-necessary quantities to compensate for low-quality base ingredients.

What to look for instead: Sodium present in the list but not prominently placed.

Rendered fat from unnamed sources

'Animal fat' without a species is the most concerning version. 'Poultry fat' is a step better - it at least identifies the category of animal. Named single-source fats like chicken fat, salmon oil, or flaxseed oil offer the most transparency.

What to look for instead: Named fat sources. Poultry fat is acceptable. Anonymous animal fat is not.

How to Read the Guaranteed Analysis

The guaranteed analysis shows minimum protein, minimum fat, maximum fibre, and maximum moisture. Benchmarks for adult dogs:

  • Protein: 25%+ crude protein from quality named sources
  • Fat: 10-16% is a reasonable range. Lower suits dogs prone to weight gain or pancreatitis.
  • Fibre: 3-6% crude fibre supports good digestion and firm stools

Protein percentage isn't quality. A food can have 30% protein while most comes from plant sources or low-quality by-products.


What Good Ingredients Look Like

  • Named protein first: New Zealand lamb, cage-free chicken, wild salmon
  • Quality fibre sources: sweet potato, chicory root, beet pulp
  • Named fats: chicken fat, salmon oil, flaxseed
  • Natural preservatives: mixed tocopherols, rosemary extract, vitamin C
  • No added sugar, no artificial colours, no unnamed by-products

Happy Hour: What the Good List Looks Like in Practice

Happy Hour is a NZ-made, grain-free formula. Running it through the criteria above:

  • Named NZ protein sources: grass-fed New Zealand lamb as the primary ingredient
  • No unnamed by-products
  • Grain-free: no wheat, corn, or soy
  • Natural preservatives only: citric acid, acetic acid, mixed tocopherols, rosemary extract
  • No artificial colours or flavours
  • No added sugars
  • Functional additions: green-lipped mussel, manuka honey, prebiotics, chelated minerals

The Bottom Line

The pet food industry relies on most owners not reading labels carefully. Once you know what the terminology actually means, the quality differences become obvious. Your dog eats the same food every day. It's worth two minutes reading what's actually in it.

Frequently Asked Questions

What dog food ingredients should I avoid in NZ?

Avoid artificial preservatives like BHA, BHT, and ethoxyquin, as well as artificial colours, flavours, and fillers like corn syrup. Vague ingredients such as "animal digest" or "meat by-products" are also worth steering clear of. Look for named proteins as the first ingredient.

Is meat meal bad for dogs?

Not always. Named meat meals like "chicken meal" are a concentrated protein source and can be perfectly fine. The concern is with generic "meat meal" or "animal by-product meal" where the source is unknown. A named protein as the first ingredient is a good sign.

Are preservatives in dog food harmful?

Natural preservatives like mixed tocopherols (vitamin E) and rosemary extract are generally safe. Synthetic preservatives like BHA, BHT, and ethoxyquin are more controversial and best avoided where possible.

How do I read a dog food label in New Zealand?

Ingredients are listed by weight, so the first few ingredients make up most of the food. Look for a named protein (chicken, lamb, beef) as the first ingredient. Avoid vague terms like "meat by-products" or long lists of fillers and additives.

Is grain-free dog food better for dogs?

Not necessarily. Grains like rice and oats can be a healthy part of a dog's diet. Grain-free is a sensible option for dogs with specific grain sensitivities, but it is not automatically healthier for all dogs.
