Frequently Asked Questions

How will WS-01® help my dog?

WS-01® supports healthy weight by targeting the key drivers of weight gain. It helps your dog burn fat more efficiently, maintain lean muscle, and support gut health, all without changing their regular diet. Over time, this can lead to better energy, mobility, and overall wellbeing.

What makes WS-01® different from weight control dog food?

Most weight control foods require a full diet change and often use lower-quality fillers or reduced portions.
WS-01® works differently. It’s a targeted supplement you simply add to your dog’s existing food, delivering clinically backed ingredients at effective doses without disrupting their routine.

Is it safe for senior dogs or dogs on medications?

WS-01® is formulated with well-studied, dog-friendly ingredients and is generally safe for daily use, including for senior dogs.

If your dog is on medication or has a specific condition, we recommend checking with your veterinarian before starting any new supplement.

How long before I see results?

Many owners notice improvements in energy and activity within a few weeks.
For visible weight and body composition changes, consistent use over 6–9 weeks is recommended.

Can picky dogs eat this powder?

Yes! WS-01® is designed to mix easily with food and has a taste most dogs enjoy. In fact, a high percentage of dogs accept it without issue. For picky eaters, start with a smaller amount and gradually increase.

What if it doesn't work?

You’re fully covered by our 90-day satisfaction guarantee. If it’s not the right fit for your dog, we’ll make it right, no stress, no risk.

Do I need to change my dog’s food or reduce portions for the supplement to work?

No need. WS-01® is designed to work alongside your dog’s current diet. You don’t need to switch foods or drastically cut portions. It supports better metabolism and fat utilization, making your current routine more effective.

Will my dog lose muscle while losing weight?

No. WS-01® is specifically formulated to help preserve lean muscle while supporting fat loss. Ingredients like L-Carnitine help the body use fat for energy while maintaining strength and mobility.

Is WS-01® suitable for all breeds and sizes?

Yes! WS-01® is suitable for dogs of all breeds and sizes. The dosing is tailored based on weight, so you can easily adjust the amount to match your dog’s needs.
