Skin and coat problems are among the most common reasons UK dog owners visit the vet. Whether your dog has dry, flaky skin, excessive shedding, hot spots, or a dull coat, the right supplement can make a dramatic difference.
The key ingredients to look for are omega-3 fatty acids (EPA and DHA from fish oil), biotin, zinc, and vitamin E — all of which support skin barrier function and promote a healthy, glossy coat.

Frequently Asked Questions
How long before I see results from skin supplements?
Most dogs show improvement in coat shine within 3-4 weeks. Skin conditions like hot spots may take 6-8 weeks to fully improve. Consistency is key.
Can I give my dog fish oil from my own kitchen?
While plain salmon oil is generally safe, human fish oil supplements may contain additives unsuitable for dogs. Purpose-formulated supplements have appropriate EPA/DHA ratios.
Are there any side effects?
The most common side effect is loose stools when starting too high a dose. Start with half the recommended dose for the first week.
