Every dog has different nutritional needs. Where puppies require food and supplements that support their joint and bone development, senior dogs may need supplements to support age-related problems like cognitive and arthritis.
In this blog post, we will list down the best dog supplements in Australia based on their age and breed. This list has been prepared under the observation of top known veterans that ensures that the list is vet-approved.
What are the Best Dog Health Supplements?
The best supplement for dogs depends upon their age and breed. Based on their age you need to specify what problems they are going through and what are the possible developments in which they need extra support. If you understand these two, you will be able to find the best dog health supplements for your canine friend.
Dog Supplement for Puppies
1. Bone & Joint Development Supplements
Puppies grow at lightning speed, and their bones and joints need support to keep up. Large breeds like Golden Retrievers or Great Danes are especially at risk of joint problems later in life. At this stage, puppies need the best dog joint health supplements containing Calcium, Phosphorus, Glucosamine, Chondroitin, Omega-3 (EPA & DHA) that support bone and joint development. (Source: NIH)
You might notice your pup stumbling, avoiding stairs, or limping after playing. Calcium and phosphorus build strong bones, while glucosamine and chondroitin protect joints from early wear and tear. Omega-3s ease inflammation and keep movement smooth.
2. Brain & Cognitive Health DHA (from fish oil)
A curious mind is what makes your puppy so fun to train, but their brain is still developing. DHA boosts memory, focus, and vision, helping your pup learn faster and respond better to cues.
Vitamin E protects those growing brain cells from damage and stress. Whether you’re working on toilet training or teaching basic commands, a sharp, focused pup makes your day easier and their world safer.
The best Nutritional Supplements for Dogs must contain following ingredients for brain and cognitive health support - DHA (from fish oil), Vitamin E.
3. Support gut health and reduce diarrhea
You know that horrible feeling when your puppy has runny stools, won’t eat, or shows signs of tummy discomfort. Probiotics and prebiotics balance their gut bacteria, helping them digest food better and stay regular. Digestive enzymes make sure every nutrient in their bowl gets absorbed properly. Add pumpkin or fibre for bulk and gentle relief. Ingredients for gut health and reducing diarrhea: Probiotics, Prebiotics, Digestive Enzymes, Pumpkin/Fibre.
4. Immune System Boost Colostrum
A puppy’s immune system is still being built, which means they’re more prone to illness, allergies, and skin issues. Therefore, you need dog diet supplements. Colostrum delivers natural antibodies that act like Mum’s milk—protecting them while they adjust to their new world. Antioxidants like Vitamin C and E defend against environmental stress. Zinc and selenium help your pup bounce back faster from colds or post-vaccine dips. Ingredients in the supplements for aging dogs to boost immune system: Colostrum, Vitamin C, Vitamin E, Zinc, Selenium.
5. Skin & Coat Health Omega-3 & Omega-6 Fatty Acids
Scratching, flaky skin, or a dull coat can take the shine off your pup’s playful personality. Omega fatty acids nourish the skin from within, while biotin and zinc strengthen the skin barrier and reduce irritation. If you’ve ever watched your dog scratch until they’re raw, you know how helpless that feels.

6. Overall Growth & Wellness
Every dog is different. Some eat too little, others burn energy too fast. A good multivitamin ensures your pup doesn’t miss out on essentials. Lysine supports muscle growth, energy, and immune system. Try supplements that contain multivitamins and Lysine.
Senior Dog Food Supplements
1. Cognitive Health & Memory Phosphatidylserine
If your dog seems confused, paces at night, or forgets familiar routines, it might not be “just old age.” These ingredients help preserve brain function and memory. Phosphatidylserine maintains brain cell health. DHA and EPA support focus and reduce cognitive decline. SAMe supports mood and clarity, and antioxidants protect against age-related brain damage.

Glucosamine and chondroitin repair cartilage. MSM and turmeric reduce inflammation and pain. Hyaluronic acid improves joint lubrication.
3. Immune System Support Vitamin C & E
Age can weaken your dog’s immune system, making recovery from illness slower. Having Vitamin C, Vitamin E, Zinc, Selenium, Probiotics, Mushroom Complexes ingredients in supplements strengthen immune defenses, reduce inflammation, and support gut health, where most of the immune system lives.

6. Heart, Kidney & Liver Support Coenzyme Q10 (CoQ10)
Age puts strain on your dog’s vital organs. CoQ10, Taurine, L-Carnitine, Milk Thistle, and Omega-3s ingredients in supplements help regulate heart rhythm, support detox pathways, and fuel healthy metabolism, especially in dogs prone to heart or liver conditions.
