Nutrition & Feeding

If you've ever stood in front of a shelf of pet food wondering whether to choose chicken, duck, salmon or something more unusual like turtle or insect protein, you're certainly not alone.

One question we hear regularly—whether at pet events or through conversations with customers—is, "What exactly is a novel protein?"

It's easy to assume that "novel" means better or more premium. In reality, the term has a much simpler meaning.

Understanding what a novel protein is—and when it may actually be useful—can help you make more informed decisions for your dog or cat. It also helps cut through the marketing language that often surrounds pet food.

In this guide, we'll explain what novel proteins are, when veterinarians may recommend them, and why they aren't necessarily the right choice for every pet.

What is a Novel Protein?

A novel protein is simply a protein source that your pet has not eaten before.

For many dogs and cats, common proteins include:

• Chicken
• Beef
• Lamb
• Fish
• Turkey

If a pet has been eating these proteins throughout its life, a different protein—such as duck, rabbit, venison, kangaroo, turtle or black soldier fly larvae—may be considered a novel protein for that individual animal.

The important point is that "novel" depends on your own pet's feeding history.

For example:

A puppy that has only ever eaten chicken may find duck to be a novel protein.

However, another dog that has eaten duck for years would no longer consider duck "novel" from a dietary perspective.

Why Do People Choose Novel Protein Diets?

There are several reasons why pet owners may choose a novel protein diet.

Suspected food sensitivity

One of the most common reasons is when a veterinarian suspects that food may be contributing to chronic skin or digestive problems.

In these situations, a veterinarian may recommend an elimination diet, where the pet eats a carefully selected diet using a protein they haven't previously consumed. This process can help identify whether certain ingredients are contributing to clinical signs.

It's worth remembering that not every itchy dog has a food allergy. Environmental allergies, parasites and skin infections are often much more common causes. That's why it's important to work with your veterinarian rather than changing foods repeatedly without a plan.

Dietary variety

Some owners also like rotating between suitable protein sources over time to provide variety.

While many healthy dogs and cats do perfectly well eating the same complete and balanced diet, others may enjoy different flavours if changes are introduced gradually.

Personal preferences

Some owners prefer certain protein sources for sustainability, availability or ethical reasons.

As long as the diet is complete and balanced for the pet's life stage, there can be more than one appropriate choice.

Does Every Dog or Cat Need Novel Protein?

No.

This is probably the biggest misconception we hear.

If your pet is healthy, maintaining a good weight, has normal stools and shows no signs of food-related issues, there is usually no strong reason to switch simply because a food contains a novel protein.

A high-quality diet using chicken can be just as appropriate as one using duck or another less common ingredient.

The goal isn't to chase unusual ingredients. It's to find a nutritionally complete diet that suits your individual pet.

Common Examples of Novel Proteins

Depending on your pet's feeding history, novel proteins may include:

• Duck
• Rabbit
• Venison
• Kangaroo
• Quail
• Goat
• Turtle
• Black soldier fly larvae (insect protein)

Not every ingredient will be novel for every pet.

That's why knowing what your dog or cat has eaten in the past is helpful when discussing dietary options with your veterinarian.

What About Insect Protein?

Insect protein, particularly black soldier fly larvae, has attracted growing interest in recent years.

It offers several potential advantages:

• Highly digestible protein
• Naturally contains beneficial fatty acids
• Smaller environmental footprint compared with some traditional livestock production

Because many pets have never eaten insect protein before, it may also qualify as a novel protein for some individuals.

Research into insect protein is growing, and current evidence suggests it can be a suitable protein source in complete pet foods when properly formulated. However, like any ingredient, it isn't automatically the best choice for every dog or cat.

Is Novel Protein Scientifically Proven to Be Better?

Not necessarily.

This is where marketing and science sometimes become mixed together.

Current research does not show that novel proteins are inherently healthier than traditional proteins.

Instead, they may be useful in specific situations, such as:

• Suspected food sensitivity
• Elimination diet trials under veterinary guidance
• Pets requiring an alternative protein source

For healthy pets without these concerns, there is no evidence that simply eating a novel protein leads to better overall health.

The quality of the entire diet—including nutrient balance, ingredient quality, manufacturing standards and suitability for the individual pet—is far more important than whether the protein is considered "novel."

How Should You Switch to a Novel Protein?

If you're changing foods, introduce the new diet gradually over about seven to ten days.

A simple transition could look like this:

• Days 1–2: 25% new food, 75% current food
• Days 3–4: 50% new food, 50% current food
• Days 5–6: 75% new food, 25% current food
• Day 7 onwards: 100% new food

A slower transition may be helpful for pets with sensitive stomachs.

If your veterinarian has recommended an elimination diet, follow their instructions carefully. Even small treats or table scraps can affect the results.

Common Misconceptions About Novel Protein

"Novel protein is always healthier."

Not necessarily. A complete and balanced chicken-based diet may be perfectly appropriate for many healthy pets.

"Every itchy dog needs novel protein."

Skin problems can have many causes, including environmental allergies, fleas and infections. Food is only one possible factor.

"The rarer the ingredient, the better."

Unusual ingredients don't automatically make a food more nutritious. Overall diet quality matters much more.

"Novel proteins cure allergies."

Novel protein diets don't cure allergies. They can be one tool that veterinarians may use when investigating suspected food-related reactions.

Practical Takeaways

If you're wondering whether your pet needs a novel protein diet, ask yourself:

• Has my veterinarian suggested investigating a food sensitivity?
• Has my pet eaten this protein before?
• Am I changing food because of a genuine need or because of marketing claims?
• Is the diet complete and balanced for my pet's age and lifestyle?

Keeping a simple record of the proteins your pet has eaten over the years can also be useful if dietary issues arise later.

Frequently Asked Questions

Is duck always a novel protein?

No. It depends entirely on what your pet has eaten previously.

Can healthy pets eat novel protein?

Yes. Healthy pets can eat novel proteins if the food is complete and balanced. They simply don't need one unless there's a specific reason.

Is insect protein safe for dogs and cats?

Current research suggests properly formulated insect protein can be a safe protein source for many pets. As with any diet, quality and nutritional balance are important.

Should I rotate between different proteins?

Some owners choose to rotate foods, while others feed the same complete diet for years. There isn't one correct approach for every pet.

Should I switch foods if my pet is doing well?

Not necessarily. If your pet is healthy and thriving, there may be little benefit in changing diets without a good reason.

Final Thoughts

Novel proteins have become increasingly popular, but they're often misunderstood.

Rather than thinking of them as "better" proteins, it's more helpful to think of them as different proteins that may be appropriate in certain situations.

Every dog and cat is unique. The best diet depends on their age, health, activity level, previous feeding history and individual needs—not simply whether the ingredient sounds unusual.

At Pineapple Pets, we've had many conversations with pet owners trying to understand the differences between protein sources. One thing we've learned is that people aren't just looking for unusual ingredients—they're looking for clear, trustworthy information. If this article has made the topic a little easier to understand, then we've achieved exactly what we set out to do.
