Go to the shopMax Strength and Max Strength Plus are high-spec multivitamins and minerals combined with a powerful joint supplement. They're fed as a porridge — simply add water — and can be mixed into existing food or given as a standalone snack.
The Max Strength Plus also contains serrapeptase, a natural anti-inflammatory and pain reliever.
Hip & Joint Dog and Hip & Joint Dog Plus are pure joint supplements with high doses of essential joint ingredients. The Plus version contains serrapeptase in higher doses than Max Strength Plus. These supplements are best mixed into wet food for palatability.
The dog food market is full of confusing options — kibble, wet food, raw diets, supplements… At Winston and Porter®, we believe in transparency and science-led nutrition.
The Nourish + C range was developed after extensive research to cut through the confusion. Commercial dog food is often produced at high temperatures that compromise the nutritional content — reducing efficacy and bioavailability. Raw diets are great for protein, but widely recognised as needing supplementation to ensure balance.
Our supplements are suitable for all dogs and designed to complement any feeding regime:
"Let the dog food provide the calories… Nourish + C will take care of the essentials."
We use human-grade ingredients, no buffers or fillers, and optimum levels of vitamins, minerals, essential oils, and amino acids. Every ingredient has a job to do. We're not off-the-shelf — we're innovative, and we care about your dog's individual needs.
It depends on the size of your dog. Here's a handy guide:
🐕 Small dog (0–15 kg) — 4.5g per day (also suitable for cats)
🐕 Medium dog (15–40 kg) — 6.5g per day
🐕 Large dog (40 kg+) — 13g per day
These products are available in three sizes to suit your dog:
We also offer 5 kg and 10 kg sizes, supplied in brown paper recyclable sacks.
Every pouch or tub comes with an appropriately sized scoop inside, along with feeding guidelines on the label to help you get the correct amount for your dog or horse.
Don't worry — the scoop is definitely in there! It sometimes falls to the bottom of the container, so have a good rummage first. If you still can't find it, get in touch and we'll send one out to you straight away:
