Ageing happens quietly.
The walks get shorter. The stairs take longer. It rarely happens overnight.
Grey Muzzles is the small thing you do every day about it.

Six things older dogs need most.
Joint mobility
Supports everyday movement, so walks, stairs and play stay enjoyable for longer.
Older joints work harder and recover more slowly. Daily nutritional support is aimed at comfortable movement and steady recovery after activity.
Ingredients
- Algal omega-3 DHA
- Natural astaxanthin
- MSM
- Turmeric with black pepper
Drawn from published work on omega-3 DHA, astaxanthin in dogs and joint comfort.
See the evidence →Healthy ageing
Daily nutrition made for the years that matter most, so your dog stays active and engaged.
Ageing is gradual. The formulation is built around the nutrients most studied for supporting dogs through it, given consistently rather than occasionally.
Ingredients
- Antioxidant-rich microalgae
- Natural astaxanthin
- Natural vitamin E
Antioxidant support is the most researched nutritional lever in healthy ageing.
See the evidence →Immune support
Supports your dog's natural defences, every single day.
Immune responses become less balanced with age. The aim is steady, everyday support rather than a short-term boost.
Ingredients
- Antioxidant-rich microalgae
- Brewer's yeast prebiotic fibre
- Natural vitamin E
Antioxidant-rich microalgae have been studied for their role in a balanced immune response.
See the evidence →Skin & coat
Supports healthy skin and a naturally soft, shining coat.
Coat condition is usually the first thing owners notice. It is also one of the clearest visible signals of nutrition.
Ingredients
- Algal omega-3 DHA
- Natural astaxanthin
- Natural vitamin E
Omega-3 fatty acids are the best-studied nutritional contributors to coat quality.
See the evidence →Gut health
Supports digestive wellbeing and a settled, healthy gut.
Nothing else works unless digestion does. Fibre and functional carbohydrates support slow, steady digestion.
Ingredients
- Prebiotic carbohydrates from microalgae
- Brewer's yeast prebiotic fibre
- Pumpkin and coconut fibre
Prebiotic fibre is widely studied for digestive comfort and microbiome balance.
See the evidence →Everyday vitality
Helps support energy and everyday wellbeing, for dogs who still want the walk.
Older dogs lose muscle more easily. Protein quality supports maintenance and recovery, not simply more protein.
Ingredients
- Quality proteins (chicken liver and chickpea)
- Naturally occurring taurine
- Algal omega-3 DHA
Protein quality, rather than quantity, is the focus of ageing nutrition research.
