If you’ve ever stood in front of a shelf full of pet food, you’ve probably asked yourself the same question many pet owners do:
If I’m already feeding a premium dog or cat food, does my pet really need supplements?
It’s a reasonable question.
Today, many commercial pet foods are marketed as “complete and balanced,” promising to provide everything a healthy pet needs for everyday nutrition. At the same time, the pet supplement industry continues to grow rapidly, with products designed to support joint health, digestion, skin and coat, heart health, immunity and emotional wellbeing.
So, who’s right?
Is premium pet food enough, or are supplements simply an unnecessary extra?
The answer isn’t as simple as yes or no.
For many healthy pets, a high-quality complete diet provides an excellent nutritional foundation. However, every pet is different. Age, activity level, breed, health conditions and lifestyle can all influence nutritional needs throughout life.
Rather than replacing a balanced diet, supplements are generally designed to complement good nutrition by providing targeted support where appropriate.
Let’s look at what “complete and balanced” really means—and when additional nutritional support may be worth considering.
What Does “Complete and Balanced” Really Mean?
Most reputable commercial dog and cat foods are formulated to meet recognised nutritional standards.
According to the U.S. Food & Drug Administration (FDA), a pet food labelled as “Complete and Balanced” is formulated to provide the nutrients required for a particular life stage, such as growth, reproduction or adult maintenance.
Similarly, the Association of American Feed Control Officials (AAFCO) establishes nutritional profiles that many manufacturers use when developing commercial pet foods.
These standards help ensure that healthy dogs and cats receive appropriate amounts of essential nutrients, including:
- Protein
- Fat
- Vitamins
- Minerals
- Essential amino acids
- Essential fatty acids
For most healthy pets, a complete and balanced diet is the best place to start.
However, meeting minimum nutritional requirements doesn’t necessarily mean every pet has identical nutritional needs throughout its entire life.
Just like humans, pets change over time.
A playful Labrador puppy has very different nutritional demands compared with a 12-year-old senior Labrador. An indoor cat that sleeps most of the day doesn’t require exactly the same nutritional support as an active outdoor cat.
Nutrition should always be viewed in the context of the individual pet.
Comparing Popular Dog and Cat Food Brands in Australia
Australian pet owners have more choices than ever before.
Some of the most recognised premium brands include:
Dog Food
- Royal Canin
- Hill’s Science Diet
- Purina Pro Plan
- Advance
- Black Hawk
- Ivory Coat
- Taste of the Wild
Cat Food
- Royal Canin
- Hill’s Science Diet
- Purina Pro Plan
- Advance
- Black Hawk
- Fancy Feast
- Wellness CORE
These brands are widely recommended because they formulate diets designed to provide complete daily nutrition for healthy pets.
That doesn’t mean one brand is universally “better” than another.
Each uses different ingredient sources, formulations and nutritional philosophies. Some focus on breed-specific recipes, while others prioritise high-protein formulas, sensitive digestion or weight management.
For example, Royal Canin offers breed- and life-stage-specific diets, while Hill’s Science Diet places a strong emphasis on evidence-based nutrition developed alongside veterinary professionals. Purina Pro Plan is popular among active and sporting dogs, while Australian brands such as Advance and Black Hawk are commonly chosen by pet owners seeking locally available premium nutrition.
The important takeaway is this:
These foods are designed to provide complete daily nutrition—not to “cure” health problems or meet every possible nutritional need throughout every stage of life.
Why Complete Nutrition Doesn’t Mean Every Pet Needs the Same Thing?
One of the biggest misconceptions is that “complete and balanced” means every pet will receive exactly the same benefits.
In reality, nutritional needs can vary significantly.
The World Small Animal Veterinary Association (WSAVA) recommends evaluating nutrition based on the individual animal rather than relying solely on breed or age.
Factors that may influence nutritional requirements include:
- Age
- Breed
- Activity level
- Body condition
- Digestive health
- Medical history
- Lifestyle
- Environmental stress
- Recovery from illness or surgery
For example, two Golden Retrievers eating exactly the same premium food may have completely different needs.
One may be a young, active dog competing in agility events, while the other is an older family pet beginning to experience reduced mobility.
Likewise, two indoor cats eating the same diet may differ in body condition, digestive health or stress levels depending on their environment and daily routine.
This doesn’t necessarily mean their food is inadequate.
Instead, it highlights why nutrition should be personalised rather than treated as a one-size-fits-all solution.
Can Premium Pet Food Replace Supplements?
For many healthy pets, the answer is yes.
If your dog or cat is eating a high-quality complete and balanced diet, maintaining a healthy body weight and receiving regular veterinary care, additional supplements may not always be necessary.
However, there are situations where pet owners—and veterinarians—may consider targeted nutritional support alongside a balanced diet.
These may include:
- Age-related joint support
- Digestive health
- Skin and coat maintenance
- Everyday stress
- Recovery periods
- Increased activity levels
- General healthy ageing
Rather than replacing premium pet food, supplements are intended to support specific wellness goals while allowing complete and balanced nutrition to remain the foundation of your pet’s diet.
Which Pets May Benefit From Nutritional Supplements?
A complete and balanced diet remains the most important part of your pet’s nutrition. However, just like people, dogs and cats go through different life stages that may bring different nutritional priorities.
The goal of a supplement isn’t to replace quality pet food—it’s to provide targeted nutritional support where appropriate.
Below are some of the most common situations where pet owners consider adding supplements to their pet’s daily routine.
Senior Dogs and Cats
As pets age, their nutritional priorities naturally change.
Older dogs and cats may become less active, experience changes in mobility or require additional support to help maintain healthy joints, muscles and overall wellbeing.
While premium senior pet foods are formulated for ageing pets, some owners choose additional nutritional support to complement their existing diet.
Common ingredients often used for senior pets include:
• Hydrolysed Collagen
• Bone Broth
• Calcium
• Glucosamine
• Antioxidants
• Omega fatty acids
For owners looking to support healthy mobility and connective tissues, Petmima Advanced Bone Broth + Hydrolyzed Collagen is formulated with collagen-rich ingredients designed to support healthy joints and everyday movement.

Active and Working Dogs
Dogs that regularly participate in agility, hiking, sporting activities or physically demanding work often place greater demands on their bodies than the average household pet.
Examples include Border Collies, Australian Shepherds, Labrador Retrievers, Kelpies, German Shepherds and other sporting or working breeds.
Although a complete diet provides the foundation for performance, many owners choose additional nutritional support to help maintain joint health and assist recovery following regular exercise.
Collagen-rich ingredients and bone broth have become increasingly popular among owners of active dogs because they fit easily into everyday feeding routines.
Pets With Sensitive Digestion
Digestion plays a major role in overall health.
Even when a pet is eating premium food, digestive upset can sometimes occur due to dietary changes, environmental changes, travel, stress, sensitive stomachs or antibiotic use (under veterinary guidance).
Many digestive-support supplements include prebiotic ingredients that help nourish beneficial gut bacteria and support a healthy digestive environment.
For owners looking for everyday digestive support, Petmima Digestive Balance + Prebiotics contains carefully selected prebiotic ingredients designed to complement a balanced diet and support healthy digestion.

Pets That Experience Everyday Stress
Stress doesn’t always look the same.
Some dogs bark, pace or become destructive, while some cats hide, groom excessively or become withdrawn.
Changes such as moving house, introducing another pet, thunderstorms, fireworks, travelling or veterinary visits can all affect a pet’s emotional wellbeing.
The American Veterinary Society of Animal Behavior (AVSAB) recommends reward-based training and appropriate environmental management for pets experiencing fear or anxiety.
Alongside good routines, enrichment and positive training, some owners also choose nutritional supplements that support calm behaviour as part of their everyday wellness plan.
One example is Petmima Relax & Calm + Ashwagandha contains calming-support ingredients including L-Theanine, Chamomile and Ashwagandha.

Picky Eaters and Everyday Wellness
Not every pet finishes every meal with enthusiasm.
Some pets are naturally picky, while others lose interest in food during periods of stress, ageing or seasonal change.
Although premium pet foods are formulated to provide complete nutrition, some owners prefer adding a daily nutritional topper to help support overall wellbeing.
Daily multivitamin supplements are commonly chosen by owners looking for broader nutritional support rather than targeting one specific area.
Petmima Complete Care + Multi Vitamin & Mineral combines essential vitamins, minerals and functional ingredients in a convenient food topper that can be mixed into your pet’s regular meals.
Rather than replacing a balanced diet, it’s designed to work alongside quality nutrition as part of an everyday wellness routine.
Choosing the Right Supplement for Your Pet
| Health Goal | Nutritional Support |
| Everyday wellness | Petmima Complete Care + Multi Vitamin & Mineral |
| Digestive health | Petmima Digestive Balance + Prebiotics |
| Joint health & mobility | Petmima Advanced Bone Broth + Hydrolyzed Collagen |
| Relaxation & emotional wellbeing | Petmima Relax & Calm + Ashwagandha |
Rather than replacing premium dog food or cat food, these supplements are designed to complement an already balanced diet by providing targeted nutritional support where appropriate.
Whether you share your home with an energetic puppy, an ageing senior dog, an indoor cat or an adventurous outdoor companion, choosing supplements based on your pet’s individual needs can help support long-term health and wellbeing.
In the next section, we’ll answer some of the most common questions pet owners ask—including whether supplements are safe, whether puppies and kittens need them, and how to choose high-quality products.
Frequently Asked Questions About Pet Supplements
Does my dog or cat really need supplements?
Not necessarily.
For many healthy pets eating a high-quality, complete and balanced diet, additional supplements may not be essential. According to the U.S. Food & Drug Administration (FDA), commercial pet foods labelled as ‘Complete and Balanced’ are formulated to provide the nutrients healthy pets need for their life stage.
However, nutritional needs can change over time. Senior pets, highly active dogs, pets with sensitive digestion or those experiencing everyday stress may benefit from targeted nutritional support alongside a balanced diet.
The best approach is to view supplements as part of an overall wellness routine—not as a replacement for quality pet food.
Can dogs and cats take the same supplements?
Some nutritional ingredients, such as collagen, bone broth, prebiotics and certain vitamins, may be suitable for both dogs and cats when formulated appropriately. However, nutritional requirements differ between species. Always choose supplements specifically formulated for your pet and follow the manufacturer’s feeding recommendations.
Can puppies and kittens take supplements?
Growing pets generally receive their nutritional requirements from diets formulated for growth. If your puppy or kitten has specific health concerns, consult your veterinarian before introducing any new supplement.
Are pet supplements safe?
Quality pet supplements are generally designed to complement a balanced diet. They should always be used according to the manufacturer’s instructions and should not replace veterinary diagnosis or treatment.
