Our testing protocols include checks for heavy metals, microbes, and other potential contaminants, ensuring that what reaches your pet is pure, safe, and nutritious.
how do I determine the right dosage of supplements for my pet based on their weight?
Determining the right dosage for your pet is crucial for the effectiveness and safety of our supplements.
Each product page on our website provides a detailed dosage chart based on your pet's weight. Simply locate your pet's weight range on the chart to find the recommended dosage.
It's always a good practice to start with the suggested dosage and observe how your pet reacts, then adjust as needed.
If you have any concerns or need personalised advice, we recommend consulting with your veterinarian.
can these supplements be mixed with any type of pet food?
Absolutely! Our supplements are made from single-ingredient whole foods like goat's milk powder and seaweed powder, making them a versatile addition to any pet food.
You can mix them with dry kibble, wet food, or even use them as a topper for a raw diet. However, we always recommend monitoring your pet for any changes or adverse reactions when introducing a new supplement to their diet.
And if in doubt, consulting with your veterinarian is always a good practice to ensure the suitability of the supplement for your pet's specific dietary needs.
how often should these supplements be administered? Is it safe for long-term use?
Our supplements are crafted from natural, single-ingredient whole foods, making them a wholesome addition to your pet's diet. They can typically be administered daily, but the exact frequency may vary depending on your pet's individual needs and the recommendations of your veterinarian.
As for long-term use, our supplements are designed to be a safe and nutritious part of your pet's ongoing diet.
what are the specific benefits I can expect to see in my pet after using your supplements?
Our supplements are crafted to support various aspects of your pet's health:
Goat's Milk Powder: Known for its digestive benefits, goat's milk powder can help promote a healthy gut flora, aid digestion, and provide essential nutrients like vitamins and minerals.
Seaweed Powder: Rich in vitamins, minerals, and amino acids, seaweed powder can support a healthy coat, skin, and overall well-being.
are there any known side effects associated with these supplements?
Our supplements are made from natural, single-ingredient whole foods, which are generally well-tolerated by most pets. However, as with any new addition to your pet's diet, there's a small chance of adverse reactions.
These could include digestive upset like diarrhoea or vomiting, especially if the supplement is introduced too quickly or in too high a dose initially. We recommend starting with a smaller dose and gradually increasing to the recommended dosage while monitoring your pet for any adverse reactions.
Additionally, if your pet has any pre-existing medical conditions or is currently on medication, it's always a good practice to consult with your veterinarian before introducing new supplements to their diet.
how long does it typically take to see improvements in my pet’s health?
The duration it takes to observe noticeable improvements in your pet's health can vary based on several factors including the specific supplement, your pet's initial health condition, and the consistency of supplementation. However, many pet owners report seeing positive changes within a few weeks to a month of consistent supplementation.
Digestive Health: Improvements in digestive health, such as reduced flatulence or better stool consistency, can often be noticed relatively quickly, sometimes within a week or two.
Skin and Coat Health: For benefits like a shinier coat or healthier skin, it might take a few weeks of consistent supplementation.
Joint Health: Improvements in joint health and mobility may take a bit longer, sometimes up to a month or more, as joint tissues take time to repair and regenerate.
It's crucial to follow the recommended dosage guidelines and maintain a consistent supplementation routine to see the best results. Additionally, every pet is unique, so what works quickly for one pet may take longer for another.
what is the shelf life of your supplements?
Generally, the shelf life of our supplements is around 6 months from the date of manufacture, when stored as directed on the packaging.
We recommend checking the "Best By" date printed on the packaging of each product to ensure you are using it within the recommended timeframe. It's also advisable to store our supplements in a cool, dry place away from direct sunlight to maintain their efficacy and quality over time.
what is your return policy in case I’m not satisfied with the product?
We stand behind the quality and effectiveness of our natural pet supplements.
However, we understand that every pet is unique and may react differently to supplementation.
Though we cannot accept returns on products once they are opened due to their natural composition, we offer a 30-day money-back guarantee from the date of purchase in case you are not satisfied with the product.
