Walk into any pet store or scroll any pet site in Australia and the supplement options are endless. Powders, chews, oils, tubs and treats, all promising a healthier, happier animal. The hard part is not finding a supplement. It is working out which ones are worth your money and your pet's daily routine.
Key takeaways
- Start with the goal, not the product, so you can ignore most of the aisle and focus on what is actually built for your pet's need.
- The single most useful label check is whether the key actives are quantified per serve by weight, which lets you compare pet supplements honestly.
- Match quality, weight-based dosing and an honest "support" framing, and treat hype, vague blends and one-size dosing as reasons to walk away.
At Innovet, we sell supplements, so we will be upfront: we think most owners are asking the right question and getting too little help answering it. This guide is the framework we wish every label made easy. It is about actives, dosing and quality, not packaging, and it applies whether you are buying for a dog, a cat, or both.
01Start with the goal, not the product
Before you compare brands, get clear on what you are actually trying to support. A supplement that is right for one pet can be pointless for another. Common, sensible reasons Australian owners reach for a supplement include:
- Everyday wellbeing, for a generally healthy pet, where the aim is a complete base of daily nutrition.
- Joint and mobility support, often for larger breeds, active dogs, or ageing pets.
- Skin and coat condition, for a dull coat or a pet that needs a little extra coat support.
- Life-stage or recovery support, such as a senior pet or one bouncing back after a procedure, ideally guided by your vet.
Naming the goal first means you can ignore most of the aisle and focus on the products actually built for it. If a single product claims to do everything at once, treat that as a reason to look more closely, not less.
02The label test: five things that actually matter
Once you know the goal, the label does the rest of the work, if you know what to look for.
1. Actives quantified per serve
A good supplement tells you how much of each key active is in a serve, by weight, so you can compare two products honestly. No guesswork.
2. Ingredient quality stated
Human-grade means ingredients held to the same safety and quality standards as human food. For a daily product, that standard is worth seeking out.
3. Dose matched to weight
A 4 kg cat and a 35 kg dog should not take the same serve. A weight-based routine means your pet gets an amount that suits them.
4. Honest about what it does
The best supplements describe themselves as nutritional support. Anything promising to cure, treat or guarantee an outcome is telling you to be cautious.
5. A format your pet will take
The best formula is useless on the floor. Powders, oils and treats all work; match the format to your pet's habits, not the marketing.
03Dogs and cats: what changes
The framework above holds for both species, but a few things shift between them.
Cats are smaller, often fussier, and very particular about texture and taste, so format and palatability matter more. Dosing should always scale to their lower body weight. Dogs vary enormously by size and activity, so a large, active or working dog has very different needs from a small companion dog. In a multi-pet household, a weight-based supplement that suits both species saves you running two systems, as long as you measure each pet's serve to their own weight.
04Supplement, treat, or both?
You do not have to choose between a measured supplement and a treat your pet enjoys. Many owners use both: a daily supplement as the foundation, and a functional treat for training, rewards or the days when a measured serve is a hassle. The rule stays the same for each. The treat should still tell you what is in every piece, by weight, rather than leaning on the word "supports".
It is about actives, dosing and quality, not packaging. Anything promising a miracle is telling you to be cautious.Innovet, on choosing a pet supplement
05Red flags worth walking away from
A quick way to sort the trustworthy from the hype is to put the green flags next to the warning signs.
Green flags
- Key actives quantified per serve, by weight
- Stated ingredient quality and sourcing
- Weight-based dosing across different pets
- Honest "nutritional support" framing
Walk away from
- Actives with no amounts, or a vague "proprietary blend"
- Claims to cure, treat or guarantee results
- One-size-fits-all dosing across wildly different pets
- Pressure and hype doing the work quantified actives should do
None of these guarantee a product is bad, but together they tell you the brand is selling a feeling rather than nutrition you can verify.
06Where your vet comes in
A supplement supports a healthy pet. It is not a substitute for veterinary care. If your pet has a diagnosed condition, takes medication, or is showing signs of being unwell, talk to your vet before adding anything new, and let them guide products aimed at recovery or a medical concern. Used this way, a good supplement complements professional care rather than competing with it.
07A confident starting point
If you want one clean place to begin, a transparent daily supplement is the foundation most pets benefit from, with targeted products layered on for specific goals like joints or coat. That is exactly how we designed our range: Health Boost+ as the everyday base, with Joint Health+ and Skin & Coat+ for focused support, all with the actives listed per serve by weight so you can choose with confidence.

Frequently asked questions
Do healthy dogs and cats really need supplements?
A complete diet is the foundation. Supplements add targeted support, for everyday wellbeing or a specific goal like joints or coat. Choose based on a clear goal, and check with your vet if your pet has a health condition.
What is the most important thing to check on a pet supplement label?
Whether the key actives are quantified per serve by weight. That single detail lets you compare products honestly instead of relying on packaging or ingredient order.
Is human-grade actually better for pets?
Human-grade means ingredients held to the same safety and quality standards as human food. For a product your pet takes daily, that consistency and quality is a meaningful advantage.
Can I give one supplement to both my dog and cat?
You can use a product made for both species, but measure each pet's serve to their own body weight. Cats also tend to be fussier about format and taste.
Should I tell my vet about supplements I am giving?
Yes. Especially if your pet has a diagnosed condition or takes medication. Supplements support a healthy pet but should fit alongside veterinary care, not replace it.
