Itchy, flaky, or dull skin is one of the most common reasons UK dog owners visit the vet — and in many cases, the underlying cause is a nutritional deficiency rather than a disease. A skin and coat supplement addresses the gap between what commercial dog food provides and what an individual dog’s skin actually needs, delivering concentrated Omega fatty acids, biotin, zinc, and vitamin E directly to the dermal layer.
The critical insight from veterinary dermatology is the gut-skin axis: the health of a dog’s skin is directly linked to the health of their gut microbiome. Supplements that combine Omega oils with prebiotics or probiotics produce measurably better skin outcomes than Omega oils alone.
Key Ingredients for Dog Skin Health
- Omega-3 (EPA/DHA): Anti-inflammatory — reduces itching, redness, and allergic skin reactions. Best sourced from fish oil or algal oil.
- Omega-6 (GLA): Strengthens the skin barrier — reduces water loss and improves coat shine. Best sourced from borage oil or evening primrose oil.
- Biotin: Supports keratin production — essential for hair regrowth and follicle strength.
- Zinc: Repairs damaged skin, supports immune function at the dermal level.
- Vitamin E: Antioxidant — protects skin cells from environmental oxidative damage.

1. YuMOVE Skin & Coat Care Itching — Best Overall
YuMOVE (formerly YuDERM) is the UK’s most vet-recommended skin supplement brand. The “Itching” formulation combines enriched Omega-3 from algal oil, Omega-3 from golden flaxseed, and Omega-6 GLA from borage oil — targeting both the anti-inflammatory pathway (reducing itch) and the skin barrier pathway (reducing moisture loss). Developed with veterinary dermatologists. Liquid format mixes easily into food.
2. Pooch & Mutt Salmon Oil — Best Budget
The UK’s first ethically approved canine supplement company, Pooch & Mutt sources wild salmon oil rich in EPA and DHA. The pump dispenser makes dosing straightforward — one pump per 10kg body weight, added to daily food. Results typically visible within 4-6 weeks: improved coat shine, reduced flaking, and calmer skin.
