Start with the dog.
Six things change as dogs get older. Here is what we support, what goes in, and where the evidence sits.
Why does Grey Muzzles support 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.
What contributes
- Algal omega-3 DHA
- Natural astaxanthin
- MSM
- Turmeric with black pepper
The evidence
Drawn from published work on omega-3 DHA, astaxanthin in dogs and joint comfort.
Read the references →Why does Grey Muzzles support 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.
What contributes
- Antioxidant-rich microalgae
- Natural astaxanthin
- Natural vitamin E
The evidence
Antioxidant support is the most researched nutritional lever in healthy ageing.
Read the references →Why does Grey Muzzles support 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.
What contributes
- Antioxidant-rich microalgae
- Brewer's yeast prebiotic fibre
- Natural vitamin E
The evidence
Antioxidant-rich microalgae have been studied for their role in a balanced immune response.
Read the references →Why does Grey Muzzles support 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.
What contributes
- Algal omega-3 DHA
- Natural astaxanthin
- Natural vitamin E
The evidence
Omega-3 fatty acids are the best-studied nutritional contributors to coat quality.
Read the references →Why does Grey Muzzles support gut health?
Supports digestive wellbeing and a settled, healthy gut.
Nothing else works unless digestion does. Fibre and functional carbohydrates support slow, steady digestion.
What contributes
- Prebiotic carbohydrates from microalgae
- Brewer's yeast prebiotic fibre
- Pumpkin and coconut fibre
The evidence
Prebiotic fibre is widely studied for digestive comfort and microbiome balance.
Read the references →Why does Grey Muzzles support 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.
What contributes
- Quality proteins (chicken liver and chickpea)
- Naturally occurring taurine
- Algal omega-3 DHA
The evidence
Protein quality, rather than quantity, is the focus of ageing nutrition research.
Read the references →One unusual algae, chosen for a reason.
At the base of the chew is an antioxidant-rich microalgae. It grows in extreme heat and acidity, and to survive that it makes unusually high levels of protective compounds.
Alongside it we use algal omega-3 DHA, natural astaxanthin, MSM and turmeric, prebiotic fibre, natural vitamin E and quality proteins. Nothing is in there for decoration.
